AlthoughorganizationsareintriguedbythepotentialbenefitsofaS&OPprocess,manyfirmsstruggletoaccomplishtheintendedperformanceimprovements.Accordingtopreviousresearchroughly30percentof S&OP initiatives fail to achieve the intended results (Milliken, 2008;Wagner, 2013). Difficulties inachievingcross-functional collaborationarebelieved tobe thebiggestobstacle inachieving improvedperformance(Ambrose,2015).SuccessfulS&OPrequiresagreatdealofteamworkandcross-functionalcollaboration(Braunscheidel&Suresh, 2009; Feng et al., 2014; Ambrose, 2015). Thismeans people with different perspectives andfunctional orientations need to reach alignment to achieve a common goal. This combination ofcollaborationandfunctionalconflictisgenerallyreferredtoasconstructiveengagement(Ambrose,2015;Olivia&Watson,2011).TheobjectiveofthisresearchistoproposeanewmodeloffactorsthataffectconstructiveengagementinaS&OPcontext.Accordingly,thefollowingresearchquestionisposed:

Withrespecttothisresearchquestion,anintegratedmodelisdevelopedthatincorporatesandbuildsonmodelsproposedinpreviousresearch.Theresearchworkwasinitiatedwithawide-rangingliteraturereview to locate gaps in the current literature, and identify relevant factors enabling constructiveengagement. Next, a case study was conducted to evaluate the model in a case organization.

The remainder of this chapter holds the detailed research description, projectscope,andprojectoutline.1.1ResearchdescriptionTheS&OPprocessisatoolforbalancingsupplyanddemandforthemediumtolongterm.Theprocessusuallyconsistsoffourmonthly-recurringmeetings(Milliken,2008;Olivia&Watson,2010).Manyarticleshavebeenwrittenaboutthistopic,withanoticeableincreaseininterestoverthelastfivetotenyears(Ambrose,2015).However,manyofthearticlesoriginatefrompractitioners’literature,whichseemstohaveatendencytodescribebestpracticecases,butfailtoidentifytheunderlyingfactorsofthesuccess.Specifically,thedevelopmentandearlyimplementationofaS&OPprocessislargelyundiscussed,whilethe potential benefits of S&OP and the different levels of maturity are discussed more extensively(Ambrose,2015;Thoméetal,2012).Inordertoachievetheintendedbenefitsanddevelopamorematureprocess, an organization has to start with a very basic S&OP process that is supported by the teammembers(Wallace&Stahl,2008).ThehighnumberoffailedS&OPinitiativesdescribedintheliteratureindicatesthedifficultyofestablishingevenabasicS&OPprocess,andprovidesthemotivationforfurtherresearchinthecrucialearlystagesofthedevelopmentandimplementationofaS&OPprocess(Singh,2010;Grimson&Pyke,2007).TheS&OPprocess isembracedbyagreatvarietyoforganizationsrangingfromfastmovingconsumergoodsproducerstocapitalgoodsmanufacturers(Milliken,2008;Olivia&Watson,2010).Thisresearchwillfocusoncapitalgoodsmanufacturers,sinceitisthoughtthatS&OPcanprovideanespeciallyvaluabletoolforthistypeofproducer.Recentdevelopmentshavegreatlyincreasedtheoperationalcomplexityformanufacturers(LaurentLimetal.,2014).Customersexpectacapitalgoodtomeettheiruniqueneedstoalargeextent.Thishasledtoanincreaseinthenumberofproductsamanufacturerhastooffer,andaresultingdecreaseinthenumberofsalesperproduct.Thishasledtocapitalgoodproducersoperatinginahigh-mix,low-volumemanufacturingenvironment.Forecastingisacrucial,ifnotthemostimportant,componentofS&OP(Wallace&Stahl,2006;Wagner,2013).ThemainintendedgoalofS&OPistostrikeabalancebetweensupplyanddemand,toachievemaximalrevenueagainstthelowestpossiblecost,resultinginmaximalprofit.However,forecastingsales

Lowoutputmeansforecasterrorsarerelativelylargeintermsofpercentages.Inmostorganizationsthesalesdepartmentisgiventhetasktocomeupwithaccurateandreliableforecasts.Thiscanleadtovariouslevelsofresistance.Since forecasts are almost inevitably wrong to some extent, sales manager might expect to receivecriticismwhenforecastsprovetobeinaccurate.ThiscandecreasetheirwillingnesstocooperateduringtheearlystagesofS&OPprocessimplementation(Milliken,2008;Grimson&Pyke,2007).Another characteristic of a high-mix, low-volumemanufacturing environment is the large number ofsuppliers.Atypicalfirmcanhavehundredsoruptothousandsofsuppliers,eachresponsibleforoneormorepartsthatmakeupthefinalproduct.Thesupplychaindepartmentisresponsibleformaintainingacloserelationshipwithsuppliers,andkeepingtrackofthecapabilitiesofthesupplier.Largeincreasesofthetypicalorderquantitymaynotalwaysbepossibleduetothesupplier’scapacity (Grimson&Pyke,2007). This again suggests the importanceof receiving accurate forecasts from the salesdepartment.Whendeviations fromthe typicalquantitiesare relayed to the supplier in time, the supplier can takeactionstomeetthenewdemandlevel.Atthesametimethesupplydepartmentshouldalsoclearlyandtimely communicate the limitations of the supply chain to the sales department. This is necessary toensurethatdemandcanbematchedbytheavailablesupplycapacities.CollaborationiskeytoachieveS&OPsuccess(Lapide,2004).However,typicallythesalesdepartmentiscustomer-facing,whilethesupplychaindepartmentissupplier-facing(Ambrose,2015).Thecontrastingfocuspointscancreatea tension field that impedesthewillingness tocollaborate.Lackingacommonunderstandingandlowlevelsofinformationsharingmakeitverydifficulttoachievetheoptimaloutputlevelsoftheorganization.Theinabilitytoachievecollaborationbetweendifferentfunctionalgroups isbelievedtobeoneofthemainreasonswhysomanyS&OPinitiativesfail(Milliken,2012;Wallace&Stahl,2008).Accordingtopreviousresearchroughly30percentofS&OPinitiativesfailtoachievetheintendedresults (Milliken, 2008;Wagner, 2014). The difficulties in achieving cross-functional collaboration arebelievedtobethebiggestobstacleinachievingimprovedperformance.InrecentresearchbyAmbrose(2015),aconceptualperformanceframeworkisdevelopedtoimprovethecurrentknowledgeabouttherelevantfactorsthatcontributetoincreasedperformanceinthecontextofS&OP.Eightvariablesaredescribedthatarethoughttoaffectthelevelofconstructiveengagement,basedonpreviousresearch.Thevariablesareacombinationoftheinternalteamfactorssocialcohesionandsuperordinate identity, and the external team factors top management support, centralization,informationquality,rewards&incentives,proceduralquality,andresourcesandtime.TheobjectiveofthisresearchistoproposeanewmodeloffactorsthataffectconstructiveengagementinaS&OPcontext.Accordingly,thefollowingresearchquestionisposed:

2. BackgroundandRelatedResearchA literature reviewwas conductedoverabroad rangeofpriorwork toassess the current knowledgeregardingS&OP,andtargetrelevantgapsintheliterature.Thefindingsarepresentedinthesub-sectionsthatfollow.First,S&OPprocessrelatedliteratureispresented.Next,theimportanceofconductingcasestudies about the S&OP process is discussed. Among several gaps in the current literature, the oneregardingthedevelopmentofacomprehensiveunderstandingofhowS&OPshouldbeimplementedwaschosenasastartingpointforthisresearchwork.Constructiveengagementwasidentifiedasthekeyfactorto achieve performance improvements associated with S&OP. Next, variables affecting the level ofconstructive engagement are explained using existing model of constructive engagement in a S&OPcontext,developedbyAmbrose (2015), andOlivia&Watson (2011).At theendof this chapter thesemodelsarecompared,andthemotivationforanewmodelisprovided.2.1SalesandOperationsplanning(S&OP)Intoday’sdynamiceconomicenvironmentcompaniesarefacedwithanincreasinglycompetitivemarket.Globalization, market uncertainty and increasing supply chain complexity raise challenges forcoordinationofbusinessprocesses(LaurentLimetal.,2014).Theproductionofcapitalgoodsbecomesincreasinglymorecomplexandresource-intensive.Ascompaniesmakeuseofglobalsourcing,longerorvariable lead times become more common. Therefore, more and more companies are turning theirattentiontotheoptimizationofthesupplychain.Supplychainmanagementisbasedontheconceptofformingtraditionallynon-coordinatedbusinessunitsintoaunified integratedorganizationalunitalongthesupplychaintocoordinatethebusinessprocesseffectivelyformsupplierstothecustomers(Fengetal.,2013).Salesandoperationsisaconceptrelatedtosupplychainmanagementwhichhasgainedalotofrecognitionoverthepastdecade.ArecentstudyofglobalmanufacturersbyProkopets(2012)shows70%ofthestudyparticipantshadimplementedanS&OPprocess.S&OPprovidesan instrument forboth thehorizontalalignmentofdemandandsupplyplans,and theverticalalignmentofbusinessstrategyandoperationalplanning.(Fengetal.,2013;Wagneretal.,2014).Thegeneralobjectiveismatchingthedemandandsupplyinthemedium-longtimehorizon.S&OPservesas a communication and decision making process that addresses volume and product mix and thecompany’skeyresources(Xuetal.2009).S&OPisamonthly-basedtacticalplanningprocess,whichisledbyseniormanagementandisorientedtowardsthebalancingofdemandandallthesupplycapabilitiesofproduction,distribution,procurement,andfinancetoensuretheplansandperformanceofallbusinessfunctionsarealignedtosupportthebusinessplan(Ling,2002;AberdeenGroup,2004;Bower,2005).AligningbusinessstrategyandoperationalplanningisrequiredforsuccessfulS&OP.Toachievealignmentseveralcoordinationmechanismshavetobeputinplace.Coordinationistheprocessofcommunicationanddecisionmakingamongasetofactorstoachievecommongoals(Malone,1987).Inthecontextofsupplychainmanagement,coordinationisrealizedwhenthedecisionsarebeneficialtothesupplychainasawhole(Gupta&Weerawat,2006).Thedecisionsaboutproductionandprocurementquantitiesto

The main goals of salesrepresentatives are to grow revenue andbe flexiblewith the customer requirements. This leads to apreferenceforawideproductvarietyandsaleswithafullspectrumofavailableproducts(Singh,2010).In contrast,manufacturingmanagersareoftenevaluatedand incentedbasedon theefficiencyof theproductionprocess.Thisleadstoapreferenceforanarrowproductscopeandlowinventorylevels(Olivia&Watson,2010;Shapiro,1977).Fromasocialperspective,salesmanagershavegenerallyalwaysbeeninvolved in the sales and marketing departments, while production plant managers have ascendedthroughproductionasforemenandproductionsupervisors.Theresultingdifferenceinspecificknowledgeleadstoadifferentwayinthinkingandcommunicating,andadifferenceinculture(Konijnendijk,1993,Shapiro,1977).FurtherchallengesregardingS&OPinvolvetheimplementationandapplication.AlthoughtheliteraturemakestheS&OPprocessappeareasytounderstand,manyorganizationsfacedifficultieswhentryingtoachievetheexpectedbenefits(Bower,2005).TheliteratureonlyprovideslimitedunderstandingofhowtheperformancecanbeimprovedwiththeimplementationofS&OP(Thoméetal,2012).Theseproblemsindicate that the literaturedoesnot currentlyprovide clearguidelines for the companies to follow toachieve a successful S&OP process. Especially methods to facilitate coordination between differentfunctionaldepartmentsareneeded.Thisisduetotheunderstandingthatawell-maintainedrelationshipbetweendifferentfunctiongroupsenhancesthefirmperformance(Flynnetal.2010).Previous literature reviews on the S&OP process have provided a better understanding and someguidelinesforpracticaluse.Thoméetal.(2012)conductedasystematicliteraturereviewtoofferempiricalevidenceoftheeffectofS&OPonfirmperformance.Thisreviewshowedthereisatleastpartialevidencethatcross-functionalplanningprocessescanminimizethenegativeeffectofcontradictingperformancemeasures on firm performance.

The company’s goalofimplementing S&OP was to achieve functional alignment and improve firm performance. It washypothesizedthatS&OPhasanintermediaterolebetweenthestructuraldeterminantsofcross-functionalalignmentandfirmperformancethroughthemediatingeffectsofproceduralquality,informationqualityand alignment quality. It was found that achieving alignment in the execution of plans can bemoreimportantthaninformationalandproceduralquality.In their literature review, Tuomikangas & Kaipia (2014) reiterate the need for empirical research tocomplementtheexistingmodelingandsimulationstudiesinthefield.Theirstudyrevealsthreearticles(includingtheonebyOlivia&Watson(2010)discussedabove)thatreportonthecasestudiesthatwereconducted.ThestudybyIvert&Johnsson(2010)describestheuseofadvancedplanningandschedulingsystems(APS)intheS&OPprocess.Thestudyreportsthatthiscombinationledtobenefitsregardingthelearningeffects,thesupportofdecisions,andtheplanningefficiency.ThethirdpaperbyCollin&Lorenzin(2006)focusesonhowcollaborativeplanningcanincreasetheagilityofsupplychains.Theirarticleisofamoredescriptivenature,anddescribesthelessonslearnedfromcollaborativeplanning.Itisarguedthatcustomers’demandcouldbebetterusedbysupplierstoachievemoreagilityandaligningsupplychains.Furthermore, they conclude that collaborative applications in information technology can bringmoreformalizationtotheplanningprocess.Fromthepreviousliteraturestudies,itcanbeconcludedthatthereisaneedforfurtherempiricalresearchinvolvingthesalesandoperationsplanningprocess.EspeciallyconductingcasestudieshasthepotentialtoprovidepractitionersvaluableinformationandgainfurtherunderstandingofS&OP.ResearchGapsThereviewoftheexistingliteratureinvolvingS&OPuncoversseveralresearchgaps,asreportedinstudiesbyTuomikangas&Kaipia (2014)andThoméetal. (2012).Twokeyresearchgapsareselected for thisthesisresearch.Theseare:
1. ThedevelopmentofacomprehensiveunderstandingofhowS&OPshouldbeimplemented2. Limitedempiricalresearch(e.g.casestudies)involvingS&OP.
Inthefollowing,weelaborateontheseresearchgaps.ThedevelopmentofacomprehensiveunderstandingofhowS&OPshouldbeimplementedAlthoughthechallengesassociatedwiththeimplementationofS&OParedealtwithwidelyinpractitionerliterature,thisaspectisalmostcompletelyabsentfromacademicliterature.CurrentacademicresearchoffersfewguidelineshowtomakeoptimaluseofthecapabilitiesofS&OP(Tuomikangas&Kaipia,2014).The lack of research on this topic seems odd, given the high implementation costs and high level of
13
expectedbenefits.ThestudybyGrimson&Pyke(2007)proposesaframeworktoassesstheS&OPprocessmaturityatanorganization.The five integrationstagescanhelpmanagers indetermining thecurrentS&OPmaturity,andchoosingstepstoimprovetothenextstage.Inthisresearchavarietyoforganizationsareinterviewed,rangingfromjob-shopproductiontohigh-volumecommodityproduction.ThisresearchhoweverdoesnotprovideguidelinefortheimplementationoftheS&OPprocess.FutureresearchshouldfocusonprovidingguidelinesformanagersintheprocessofimplementingaS&OPprocess.LimitedempiricalresearchinvolvingS&OPLimitedempiricalresearchintheformofcasestudiesabouttheS&OPprocessinthecurrentacademicliterature has beenmentioned on several occasions in this thesis.Most of the empirical evidence inpreviouspapershasbeengatheredusing interviewsandsurveys.Theuseofacasestudyoffersan in-depthlookintotheimplementationprocessatanorganization.Thiscanprovidevaluableinsightintothelessons and pitfalls of S&OP implementation that can provide guidance for organizations planning toimplementtheprocess.ResearchgapanalysisTheliteraturestudyprovidedtwokeygapsinthecurrentS&OPrelatedresearch.First,limitedempiricalstudiesthroughcasestudiesprovidedthemotivationforaresearchwithacasestudydesign.Second,since many companies seem to struggle at the development and early implementation stages, thisresearch focusses on the development of a comprehensive understanding of how S&OP should beimplemented.Thefocuswillbeonthefactorsthataffectconstructiveengagement.Thenextsub-sectionselaborateontheroleofconstructiveengagementinaS&OPcontext.2.2CrossfunctionalcollaborationThebalancingofdemandandsupplyactivitiesinvolvesandrequiresinputfromvariousfunctionalgroups.Sales,marketing,finance,R&D,manufacturingandpurchasingareinvolved,amongothers.ThereforetheS&OP process requires a cross-functional effort (Braunscheidel & Suresh, 2009). The collaborationbetweenthefunctionalgroupsoftenprovestobeachallengefororganizations.Themainreasonsforthisarethedifferencesinspecializations,prioritiesandincentives,astheyoftencauseconflictswithrespecttohowsupplyanddemandshouldbebalanced(Shapiro,1977).TheS&OPprocessrequiresahighlevelof collaboration in the SupplyChain (McCarthy&Golicic, 2002). In his researchpaperNakano (2009)categorizestheconceptofcollaborationintothreedimensions:
1. Sharingresources2. Collaborativeprocessoperation3. Collaborativeprocessimprovement
Sharing resources means the sharing of standardized information such as forecasts, and data aboutinventory, production and purchasing. Furthermore, customized information such as operationalconstrains, resources, and factors of demand fluctuation are used (Nakano, 2009). The collaborativeprocessoperationreferstotheinvolvementofforecastsintotheplanningattheManufacturingCenters.Deviationsbetweentheforecastsandtheplanningareexamined,andplansofactionareconstructedif

necessary. Continuous process improvements are required to stay flexible in the fast-changing globalenvironment.Therefore,organizationsmustincorporatecollaborativeprocessimprovement.Thismeansfirmshavetoimproveexistingprocesses,eliminateunnecessaryprocesses,andredesignorganizationalrolesandresponsibilities.The research by Nakano (2009) has provided findings that prove the positive effects of collaborativeforecasting and planning on the logistics production and performance (as depicted in the model,presentedinFigure4).Thelogisticsproductionandperformancewasmeasuredusingquestionnairesat65Japanesemanufacturingfirms.Theperformanceindicatorsincludedlogisticcosts,orderfillrate,anddeliveryspeed.Collaborative forecastingandplanningcanbedonewithsuppliers,withcustomers,orinternal.InternalcollaborativeforecastingandplanningistheintegralpartoftheS&OPprocess(andthetopic of this thesis). Although Nakano (2009) proves the positive effect of S&OP of the logisticsperformance, the research does not report how internal collaborative forecasting and planning isachieved.

2.3ConstructiveEngagementSuccessfulS&OPrequiresagreatdealofteamworkandcross-functionalcollaboration(Braunscheidel&Suresh, 2009; Feng et al., 2014; Ambrose, 2015). Thismeans people with different perspectives andfunctionalorientationsneedtoworktogethertoreachacommongoal.Thiscombinationofcollaborationand functional conflict is generally referred to as constructive engagement (Ambrose, 2015; Olivia &Watson, 2011). Themodel proposed in this thesis integrates and builds on twomodels proposed inpreviouswork;theS&OPperformancemodelbyAmbrose(2015),andtheplanningprocessqualitymodelbyOlivia&Watson(2011)S&OPPerformancemodelbyAmbrose(2015)The S&OP performance framework by Ambrose (2015) identifies internal team factors, contextualinfluencers, and environmental factors, and their effects on S&OP performance. The model of thisframeworkispresentedinFigure5.Theframeworkisbasedongroupeffectivenesstheoryandisvalidatedusingalargescalesurvey-basedresearch.Constructiveengagementispresentedasacentralfactorinthismodel,indicatingthecrucialroleitrepresentstoachieveimprovedS&OPperformance(Ambrose,2015).

Figure5:ModelofS&OPperformance(Ambrose,2015)
InternalTeamFactors:The internal team factors, social cohesion and superordinate identity, are necessary to achieve teamchemistryand constructiveengagement. These factorsdefinehowcomfortablepeoplearewithin theteam,andhowmuchtheyfeelpartoftheteam.Social cohesion can be defined as the strength of interpersonal connections between teammembers(Hogg,1992).Thepresenceofsocialcohesioncanstimulateexchangeofresourceswithinteams,andthuscontributetoimprovedcollaboration(Nakata&Im,2010).Superordinate identitymeasures thecognitivecomponentof therelationamember feels towardstheteam(Sethi,2000).Itdefinestheextenttowhichmembersarecommittedtosharedgoals,andhaveasignificantpart in thesuccessor failureof thecollectivetask (Nakata& Im,2010).Strongpresenceofsuperordinateidentitycanmitigatefunctionalbiasesanddevelopagroupidentity.Alackofsuperordinateidentitycandecreasegroupeffectivenessduetolowerlevelsofknowledgesharing.ContextualInfluencers:ThecontextualinfluencersaretheexternalteamfactorsthatdefinethecontextoftheS&OPteamwithintheorganization.Thesefactorsdescribethequalityoftheprocessandinformation,aswellasthesupportoftopmanagementandhowthistranslatestotheavailableresourcesfortheteam.Topmanagementsupportisidentifiedasacriticalcomponentforthesuccessofavarietyoforganizationalchanges (Li & Ling, 2006). Top management refers to senior level managers, who are involved withformulating the strategy and tactical moves of the organization. Topmanagement support becomesapparentintheappropriateallocationofresources,directinvolvementintheprocessandcommunicationfromseniormanagers.Informationqualitydefinesthedegreeofappropriatenessandusefulnessofinformationsharingfortheteammembers anddecisionmakers (Olivia&Watson, 2011).

ProceduralqualityisdefinedbyOlivia&Watson(2011)as“thedegreetowhichaprocesscontinuouslyensures that the rules of inference used to validate information, and to make decisions within andbetween functions, are appropriate and sound.” Procedural quality is a structuringmechanismwhichensuresorganizationalactivitiesaregovernedbyestablishedrulesandprocedures(Nakata&Im,2010).Rewardsand incentives refers to theextent towhich teammembersare recognizednot just for theiroperationaltask,butspecificallyfortheircontributionstoachievingteam-basedgoals(Ambrose,2015).Jointrewardsareawayoflinkingaworker’sincometooutcomesofcross-functionalteamwork.Aligningrewardsandincentiveswithteamgoalsisoftenfoundtobedifficulttoachieve.Thepersonalcontributiontowardsteamsuccessorfailurecanhardlybequantified,makingitdifficultforamembertoassessthefairnessoftherewardsystem.Still,committingteammemberstodevelopcommongoalsthroughalignedincentivesisseenasanimportantfactorforachievingcollaboration(Xieetal,2003).Thefactorcentralizationreferstotheextenttowhichthepowerofdecisionmakingresideswithuppermanagement.

In S&OP context,resources refer to having access to training and background information about the S&OP process(Ambrose,2015).Appropriate informationquality is another resource that can contribute to reachingteamgoals,andpromotingacommonlanguageandunderstanding.OrganizationsshouldrecognizetheimportanceofS&OPrelatedtasksandallocateadequatetimeformemberstoworkonthem(Wagneretal.,2013;Menonetal.,1997).Environmentalfactors:ThevariablesmarketturbulenceandtechnologyturbulencearefactorsthatarelikelytoaffecttheS&OPperformance (Ambrose, 2015).

Outcome:TheoutcomeofaS&OPprocessiscapturedbythefactorS&OPperformanceinthemodeldevelopedbyAmbrose (2015). The measurement of S&OP performance in the research by Ambrose (2015) wasachievedbyusingascaledevelopedbyWagneretal., (2013). In their research,Wagneretal., (2013)define the benefits of S&OP as “a vertically and horizontally aligned set ofmarketing, development,manufacturing,sourcing,andfinancialplansthatenabletheongoingbalancingofsupplyanddemand”.IntheresearchbyAmbrose(2015),theseS&OPbenefitsarelabelledasthefactorS&OPperformance.
PlanningprocessqualitymodelbyOlivia&Watson(2011)TheresearchbyOlivia&Watson(2011)reportsonasinglecasestudyatanorganizationwherecross-functional conflicts are overcome, by making use of a S&OP process. Functional conflicts betweendepartment mainly arise from misaligned incentives, which are common in many organization withdistinct sales and production functions. A process perspective is taken by Olivia &Watson (2011) toidentifytheprocessasamediatortosupportdifferentincentives,whilemaintainingtherequiredS&OPprocessoutcomes.Figure6showstheproposedmodelofplanningprocessqualitybyOlivia&Watson(2011)

OpenandTransparentProcessDuringtheircasestudy,Olivia&Watson(2011)observedaS&OPprocessthatwasopenandtransparent.Participantsweremotivatedtosharetheinformationoftheirrespectivedepartments,andtheprocessenabled each stakeholder to influence the outcomes of the process. By sharing and consolidating allrelevant information,stakeholders intheS&OPprocesswereexplicitlyconfrontedwiththeiropposingorientationsandincentives.Thisopenandtransparentprocessenabledparticipantstoreachalignment,and achieve improved performance. By motivating the participants, and enabling a platform forcollaborationandfunctionalconflict,constructiveengagementwasobservedbyOlivia&Watson(2011).Participant’sEngagementIn their model of planning process quality, Olivia & Watson (2011) identify the factor participant’sengagementasalinkbetweenperceivedbenefitsfortheparticipant,andthequalityoftheS&OPprocess.However, much more frequent in their paper is the term constructive engagement. Constructiveengagement is described as the active involvement of all stakeholders in collecting, validating, andadaptinginformation,andguardingoutcomesthatimpacttheirrespectivedepartments.Olivia&Watson(2011)observedthecrucialroleofconstructiveengagement inachieving improvedprocessquality,bypositivelyaffectingtheprocessattributesinformation,procedural,andalignmentquality.QualityofS&OPProcessOlivia&Watson (2011) identify threeelementsofS&OPprocessquality; information,procedural,andalignment quality. Information quality ensures decision making is enabled, by verifying theappropriatenessoftheformandcontentofinformation.Proceduralqualityreferstothedegreetowhichinformationvalidationanddecisionmakingarecontinuouslymonitoredforintegrity.Thethirdprocessattribute alignment quality refers to the degree to which organizational and functional goals aresupportedbyaprocess,andthattheactionsaresynchronized.Duringtheircasestudy,Olivia&Watson(2011) observed the positive impact of S&OP process quality on the quality of the S&OP processoutcomes.QualityofS&OPProcessOutcomesIntheirresearch,Olivia&Watson(2011)reportonthesocialandperformanceoutcomesofimplementinga S&OP process.

2.4AnalysisofexistingconstructiveengagementmodelsIn the previous section two models are presented that indicate the central role of constructiveengagement in a S&OP context. Themodel of S&OP performance by Ambrose (2015) identifies bothinternal and external team factors affecting constructive engagement. A positive relation betweenconstructive engagement is proposed, that can be impacted by environmental factors. The planningprocessqualitymodelbyOlivia&Watson(2011)aimsattentionattheperceptionsofS&OPstakeholders.InthemodelareinforcingstructureisproposedfromtheS&OPprocessoutcomesbacktoconstructiveengagement,flowingthroughtheperceptionsofprocessqualityandbenefitsofparticipatingintheS&OPprocess. The S&OP process is identified as a mediator that allows for improved performance, whilemaintainingmisalignedincentivesbetweendepartments.
While both models agree on the crucial role of constructive engagement to achieve performanceimprovement,somecleardistinctionsbetweenthemodelscanbemade.Tostartwith,theresearchwasconducted indifferentways.Ambrose(2015)madeuseofaquestionnaireapproachtoreachmultipleorganizations,operatingindifferentfieldsandindustries.Olivia&Watson(2011)madeuseofasinglecasestudyapproach,thatallowedtomakeobservationsandconductmorein-depthinterviewswiththeparticipants.
Thedifferentapproachesledtodifferentwaysofanalyzingandpresentingthefindings.ThefindingsbyAmbrose (2015) are analyzed quantitatively with a statistical approach. This allowed to make moregeneral statement about the findings of the research. The research by Olivia &Watson (2011) wasconducted at a single organization, making is harder to make general statement about the findings.Therefore,theirmodelwasputtogetherbycombiningfourpropositions,basedonthefindingsatthecaseorganization.
ThefocusofthetwomodelsprovidesdifferentviewsonthefactorsaffectingconstructiveengagementinaS&OPcontext.ThemodelbyAmbrose(2015)identifieseightvariablesthatareproposedtohaveadirecteffectonconstructiveengagement.Thesefactorsincludebothinternalandexternalteamfactors.AdirectpositiveeffectofconstructiveengagementonS&OPperformanceissuggested.InthemodelbyOlivia&Watson (2011) several factors are identified identically to themodelbyAmbrose (2015);constructiveengagement, information quality, procedural quality, rewards & incentives, and S&OP processperformance.ThefactorsocialcohesionproposedbyAmbrose(2011)differsfromwhatOlivia&Watson(2011)identifyasanopenandtransparentprocess.Whilesocialcohesionreferstotheextenttowhichpeople are working together, an open and transparent process refers to the willingness to shareinformation.CentralizationisdefinedbyAmbrose(2015)astheamountofdecisionmakingresidingatthetoplevelsoftheorganization.ThisconstructistheoppositeofwhatOlivia&Watson(2011)describeastheamountofinfluencetheparticipantsintheS&OPprocesshaveondecisionmaking,whichisreflectedinthefactorperceivedbenefitofparticipatingintheS&OPprocess.Superordinateidentityissimilar,butextends simply seeing benefits in participation, by feeling like a fullmember of the S&OP team. TwoexternalteamfactorsareidentifiedinthemodelbyAmbrose(2015)andareabsentinthemodelbyOlivia&Watson(2011),namelytopmanagementsupportandresources&time.ThefactoralignmentqualityreferstotheextenttowhichorganizationalandfunctionalgoalsaresupportedbytheS&OPprocess,andthattheactionsaresynchronized.ThisfactorispresentinthemodelbyOlivia&Watson(2011),butisnot

A reinforcing structure is presented, going from S&OPprocess outcomequalitybacktoconstructiveengagement,flowingthroughparticipant’sperceptions.ArelationbetweenS&OPperformanceandconstructiveengagementisabsentinthemodelbyAmbrose(2015).
ThesimilaritiesanddifferencesbetweenthesetwomodelsofconstructiveengagementinaS&OPcontextprovidethemotivationforanewmodel.Thecombinationofthesemodelsintoanintegratedmodelcanaddtotheliteraturebybuildingonfindingsfrompreviouswork,andvalidatingthenewmodelwithacasestudyapproach.Theresearchdesignthatisusedforthisresearchisexplainedinthefollowingchapter.

Ambrose(2015)functionedasthetemplate.Threeelementsfromhispaperwereusedforthisresearch:• TheS&OPperformancemodel (Figure5)• Thedevelopedquestionnaire (Appendix3–Questionnaire)• Thefindingssectionfromthepaper (Appendix2–Ambrose(2015)ResearchSummary)Thetemplateapproachusesexistingcodes.Forthisthesisresearchthecodeswerethevariablesaffectingconstructiveengagement,extractedfromtheS&OPperformanceframeworkbyAmbrose(2015).Thesevariableshavebeenexplainedinchapter2.3.Therelianceonexistingcodesimprovedthevalidityofthisresearch,sincethecodesarebasedonprovenconcepts.ThegroundedtheoryapproachwasusedintheAmbrosepaper(2015)todeveloptheS&OPperformancemodel.TheconceptsusedintheAmbrosepaper(2015)aremostlybasedonexistingliteraturethatincludestheapplicablequestionnaireitemswithquestionsandLikertscales.Sincemostoftheconceptsareoriginallydeveloped for new product development teams, Ambrose (2015) had tomake small changes to thewordingofsomequestionnaireitems.Asummaryofthemodificationsandthereliabilityoftheadaptedandnewlydeveloped scales is given inappendix4. Thequestionnairesenabledcomparisonbetweenrespondents’perceptionsregardingvariablesofconstructiveengagement.ThefinalelementoftheAmbrosepaperthatwasusedforthisresearchwasthefindingssection.Whereasthis research used observations, questionnaires and interviews to triangulate the findings, Ambrose(2015) strictly used the questionnaires. This approach made it possible to gather a large pool ofrespondents.A total of 101questionnaireswasused todraw the conclusions about the relationshipsbetweentheconceptsintheproposedS&OPperformancemode(Ambrose,2015).Thecasestudydesignistimeconsumingtoahighdegree,makingitimpossibletoaccesssuchalargenumberofrespondents.Furthermore, this single case research only represents the findings at one company, which leads to

limitationsregardingthegeneralizabilityofthefindings.Bycomparingtherichandcontext-dependingfindingsofthesinglecasestudytothefindingsoftheAmbroseresearch(2015)newinsightswerefound.Infact,Ambrosehimselfproposedin-depthinterviewsandcasestudyobservationsofS&OPteamsforfuture research (Ambrose,2015).Validating the findingsof theAmbrose research (2015) is suggestedusingastudyinafieldsetting,whereperceptionscanbecapturedfromentireS&OPteams.SelectionofFactorsinProposedModelIn this subsection the selectionof factors for theproposedmodel is explained.

3.3CaseStudyForthisresearchasinglecasestudydesignwasused.Themotivationforthisresearchdesign,alongwiththe benefits anddrawbacks of this design is presented in the following. A single case study design isdefinedasanempiricalresearchthatinvestigatesaphenomenonindepthandwithinitsreal-lifecontext(Yin,1989).Thistypeofresearchdesignisabletoprovideahighlevelofdetailandunderstandingofthecontext.Thismakes this researchespecially interesting for theS&OPprocess,whichhasnotbeenthetopicofanextensivenumberofpreviousworkincorporatingacasestudydesign.CasestudyorganizationThe case study organization for this research is a capital goodsmanufacturing firm. Four reasons arepresentedthatmakethisorganizationaviablerepresentativecaseforasinglecasestudy(Yin,1989).First,theorganizationsexperienceschallengesinachievingcollaborationbetweenthesalesdepartmentandthemanufacturingcenter,whicharequitecommonacrossawiderangeofindustrieswithasalesforcedriven demand (Shapiro, 1997). In addition the organization operates in a high-mix, low volumemanufacturing environment. This characteristic is of great importance to the business strategy, sincemakingmachinestostockcandriveupinventorycostsduetolowdemandfrequencyandalargeproductportfolio.Third,theprojectofferstheopportunitytofollowtheimplementationofS&OPfromaveryearlystage.Thedesignisstilldeveloping,andthedecisionmakingprocesscanbewitnessedfirsthand.Finally,theprojectmanagementandchangemanagementthatisrequiredforaprojectofthisscale,whichwillbring considerate changes. The first reason indicates a representative case, while the other reasonsindicateuniquecircumstanceswhichhavenotbeenextensivelydescribed inprevious research.Thesereasonssuggesttheappropriatenessofusingasingle-casestudyresearchdesign.In the section above several statement are made to argue the appropriateness of the selectedorganization forconductingacasestudy.However,several factorsprovidearguments toquestiontheappropriatenessoftheselectedcaseorganization.First,theS&OPwasintheearlystagesofworkingwithaS&OPprocess.Thelearningcurvethatcanbeexpectedwithanynewwayofworkingcouldinfluencetheperceptionsofpeopleinvolvedintheprocess.Closelyrelated,bytakingthequestionnairesduringtheseearlystagesrespondentsmayanswerbasedonexpectations,ratherthantheiractualexperiences.Besidesthestrengthsandflawsregardingtheappropriatenessofthecaseorganization,practicalreasonsplayedanimportantroleintheselectionofthecaseorganization.Apotentialcaseorganizationhadtoworkwitha S&OPprocess,bewilling to cooperate, andallow the research to takeplacewithin theirorganization.Thesepractical reasonsplayedan important role in theselectionofacaseorganization.Giventhelimitedtimeavailableforthisresearch,thechoicewasmadeforasinglecasestudydesign.Capitalgoodsmanufacturersareincreasinglyexposedtomarketchangeswhichdrasticallyincreasethecomplexityofoperations.Changesinthemarketareaproductoftheglobalizationoforganizations,andtheresultingincreaseincompetition.Improvedgloballogisticsandcommunicationhaveincreasedthecustomers’ willingness to look for the best deal on a global scale.

The high complexity associatedwith themarket of high-mix, low-volumemanufacturers gives rise toinformationasymmetry,whereanoptimalsolutionismightnotbefound,duetounwillingnessorinabilityto completely share information. Additionally, Information asymmetry is caused by the opposingfunctionalorientations,wherethesalesdepartmentiscustomer-facing;thesupplychaindepartmentissupplier-facing (Kraiselburd & Watson, 2007). A cross-functional effort is required to minimizemismatches,duetocomplexityinformationasymmetry,andcreateoperationalvalue(Lawrence&Lorsch,1967).However,differencesinspecializationarenotoriousforgeneratingconflictswithinorganizations(Shapiro,1977).
The case study organization decided to implement a S&OP process to facilitate the cross-functionalalignmentanddecisionmaking. Increased informationsharing initiatives include improved forecastingmethods,newmeetingsstructuresandaclearsetofproductionconstraints.Ahigh-levelrepresentationoftheS&OPprocessatthecaseorganizationispresentedinFigure9.Duringthedemandplanningphaseseparatesalesforecastsareunifiedinanunconstraineddemandplan.Thesupplyrequiredtomeetthisplanisinvestigatedduringthesupplyplanningphase.Inthisphasetheconstraintsofthesupplychainandtheproductionsitesaretakenintoconsideration.Inthedemandsupplybalancingphaseseveralscenariosarecreated.Ascenarioisanalyzedoncustomerimpact,andfinancialaspects.Oneormorescenariosarepresentedtotheexecutiveboard.IntheexecutiveS&OPmeetingtheproposedscenariosisreviewedandthe final plan is decided.

Figure10:ProposedmodelofFactorsaffectingConstructiveEngagement
4.1ConstructiveEngagementIn the literature the term constructive engagement refers to the combination of collaboration andfunctional conflict (Olivia&Watson, 2011). Constructive engagement plays a central role in both theproposedmodelsofOlivia&Watson(2011)andAmbrose(2015).Thischoicemakessense,asoneofthecorepropositionsoftheS&OPprocessisachievingformalizedcollaborationbetweenthefunctionsthatmanagesupplyanddemand(Wallace&Stahl,2008).

Constructiveengagement-CollaborationOnce sales and operations recognize and embrace their shared responsibilities, performance can beimproved through collaboration (Alexander, 2013;Wallace& Stahl, 2008). Collaboration is facilitatedthroughtherecurrenceofoneormoreS&OPmeetingsperplancycle,withthegoaltoachieveoverallalignmentand reach consensuson thedemandand supplyplanning (Stahl, 2010).Besides the formalformsofcollaboration,researchalsoindicatestheneedforinformalformsofcollaboration(McCormack&Lockamy,2005).Infact,highlevelsofinformalcollaborationaresuggestedaspreliminaryindicatorsofaS&OPprocessdonewell(Olivia&Watson,2011).Truecollaborationgoesbeyondthemeresharingofinformation, anddependson theworkers’ ability tobuild trust and relationship, and learn fromeachother’sexpertise(Ellingeretal.,2006).Constructiveengagement-FunctionalConflictGiventheirdifferentorganizationalorientationsandscopeofresponsibilities,conflictsareinherentwhensalesandoperationscollaborate(Shapiro,1977).Whileachievingcross-functionalcollaborationisacoregoaloftheS&OPprocess,thisdoesnotanimpliedabsenceofconflict(Ambrose,2015).Infact,theS&OPoffersaforumwherepresentingdifferentopinionsisencouraged.Thetermfunctionalconflictreferstothebeliefthatdifferentfunctionswillalwaysexperiencesomedegreeofdisagreement,butthatdisputescanalwaysberesolvedinafriendlyorevenconstructiveway(Morgan&Hunt,1994).Opendialogueandopenconflictresolutionsarementionedasindicatorsoffunctionalconflict(Mello,2010;Stahl&Wallace,2012).
4.2SocialCohesionThefirst internalteamfactor issocialcohesion,andconcernstheextenttowhichthemembersoftheS&OPteammaintaincollegialityandenjoyworkingtogether.Previousresearchhasidentifiedthepositiveeffects interpersonal social ties haveon exchangeswithin team (Cohen&Bailey, 1997;Nakata& Im,2010). Although social cohesion has not been studied extensively in an S&OP context, it has beenidentified as an important factor in facilitating communications between different functional groupswithinnewproductdevelopmentteam(Ambrose,2015;Moenaertetal.,1994).Dougherty(1992)statesthepositiveemotionsassociatedwithsocialcohesionarehelpfulinovercomingthenegativestereotypesthatpreservefunctionalsilos.Beingabletoseethevalueindifferentfunctionalperspectivesisbelievedto be a necessity for constructive engagement, given the cross-functional nature of S&OP teams(Ambrose,2015).However,highlevelsofsocialcohesioncanactuallyhinderthequalityoftheprocess.Sethietal.(2001)foundsocialcohesionbeyondmoderatelevelscanhampertheinnovativenessofnewproductdevelopmentteams.Moregeneralized,Souder(1998)suggestteampotencyislostthemomentpeoplebecometoocomfortablearoundeachotherandtheedgesarelost.Groupthinkoccurswhenthestrong desire for conformity is pairedwith insufficient investigation of alternatives (Janis, 1982). Thisphysiologicalphenomenoncausesthelossofcreativityandimpairscriticaldecisionmaking(Janis,1982;Sethietal.,2001).InthequantitativeresearchbyAmbrose(2015)aninverted-Uassociationbetweensocialcohesionandconstructiveengagementwasproposed.Thistypeofrelationindicatesincreasedlevelsofsocialcohesionleadtoahigherlevelofconstructiveengagement,butafteracertainpointthepositiverelationhaltsanddecreases.Thispropositionis in linewiththefindings intheliteraturethatsuggestmoderatelevelsofsocialcohesionaredesired,buthighlevelscanstiflecriticaldialogueandleadtodecreasedcreativityandevengroupthink(Janis,1982;Sethietal.,2001).Contrarytotheseexpectation,findingsofthequantitativeresearchbyAmbrose(2015)suggesthighlevelsofsocialcohesionaid,nothinder,thefunctionalconflictaspectofconstructiveengagement.Thissignificantrelationis inlinewithfindingsfromanewproductdevelopmentstudy,wheresocialcohesionissuggestedtopositivelyaffectperformanceinjoinplanning

4.3SuperordinateidentityThesecondinternalteamfactorissuperordinateidentity,andconcernsthecognitiverelationamemberfeelstowardstheteam(Sethi,2000).Itdefinestheextenttowhichmembersarecommittedtosharedgoals, andhave a significant part in the success or failure of the collective task (Nakata& Im, 2010).Superordinate identity has received little research in an S&OP context (Ambrose, 2015). However,previousresearchsuggestssuperordinateidentityplaysakeyroleininnovativeness(Sethietal.,2001),and cross-functional integration (Nakata & Im, 2010) in similar multi-functional teams. Despite theapparentadvantagesofsuperordinateidentity,existenceoffunctionalbiascanproveitdifficulttoformagroupidentityforS&OPteams(Alexander,2013;Wallace&Stahl,2008).Difficultiesespeciallytendtoexistwhendepartments fight over scarceorganizational resources (Mello& Stahl, 2011). Since S&OPteamsareexpectedtopersistindefinitely,achievingsuperordinateidentitydespitefunctionaldifferencesissuggestedtobeespeciallyrelevantinanS&OPcontext(Ambrose,2015).InthequantitativeresearchbyAmbrose(2015)apositiverelationbetweensuperordinateidentityandconstructive engagement is suggested. The findings confirmed a significant, positive effect on cross-functionalengagement.Thesefindingsareconsistentwithgroupeffectivesliterature(Nakata&Im,2010),andsuggestmembersthatvaluetheirmembershipandarecommittedtosharedgoalsaremorelikelytoconstructivelyengageinS&OPteams(Ambrose,2015).Thisleadstotheinclusionofthefollowingfactorandeffectintheresearchmodel:Proposed factor and effect:Superordinate identity,which has a direct positive effect on constructiveengagement.
4.4TopManagementSupportThe first external team factor is top management support. Top management refers to senior levelmanagers,whoareinvolvedwithformulatingthestrategyandtacticalmovesoftheorganization.Someresearchersviewthesupportofseniormanagementasthesinglemostcriticaldriverofsuccessforanysignificant organizational change (Balsmeier & Voisin, 1996; Li & Lin, 2006). Furthermore, topmanagementsupportisidentifiedasaprerequisiteforgroupeffectiveness(Cohen&Bailey,1997),andcross-functionalcollaboration(Wong,2012).InanS&OPcontext,sustainedtopmanagementsupportisreferred to as the singlemost important element required for a successful S&OP process by leadingconsultants(Boyer,2009;Grimson&Pyke,2007;Milliken,2008;Wallace&Stahl,2008).InthequantitativeresearchbyAmbrose(2015)apositiverelationbetweentopmanagementsupportandconstructiveengagementissuggested.Contrarytoexpectationsbasedontheidentificationinpreviousresearch of topmanagement support as a critical success factor, a non-significant negative effect onconstructiveengagementwasfoundbyAmbrose(2015).Theresultsfromthequantitativeresearchseemto indicatetopmanagementdoesnotdirectlyaffectconstructiveengagement,orS&OPperformance.However, Ambrose (2015) argues the timing of top management support should be taken intoconsideration. The respondents in the research by Ambrose (2015) had an average of 8 years ofexperience inworkingwith a S&OPprocess, andnoneof the respondentshad less than6monthsofexperience.Furthermore,Ambrose(2015)explainsthecrucialroleoftopmanagementsupportduring

thesettingupoftheinitialS&OPprocess.Thisprovidesthemotivationfortheinclusionofthefollowingfactorsandeffectintheproposedmodel:Proposedfactorandeffect:Topmanagementsupport,whichhasadirectpositiveeffectonconstructiveengagement.
4.5CentralizationThesecondexternalteamfactoriscentralization,andreferstotheextenttowhichthepowerofdecisionmakingresideswithuppermanagement.Centralizedorganizationsarecharacterizedbytheconcentrationofdecisionmaking locatedatthetopleveloftheorganization(Dewar&Werbel,1979).High levelsofcentralizationhavebeenfoundtoobstructthefairexchangeofinformation,andconstructivefunctionalconflict((Menonetal.,1997).Furthermore,lowautonomynegativelyaffectsgroupmotivationandtheabilitytogeneratealigneddecisionmaking(Trent&Monczka,1994).Ontheopposite,empowermentandincreasedautonomyare found tobedecisive for successful teams (Hollandet al., 2000).ResearchbyGuenter&Grove(2012)determinedemployeesaremorewillingtoparticipateincollaborativeplanning,whentheyperceivetheirrolesasimportanttotheoutcomes.S&OPliteratureidentifiesdecentralizationofdecisionmakingasakeysuccessfactorfortheS&OPprocess(Lapide,2004).In the quantitative research by Ambrose (2015) a negative relation between centralization andconstructive engagement is proposed. The findings indeed showed a negative relation approachingsignificance,meaninghigh levelsofcentralizationare likely tohaveanegative impactonconstructiveengagement.Thesefindingsleadtothefollowingfactorandeffectincludedintheproposedmodel:Proposed factor and effect: Centralization, which has a direct negative effect on constructiveengagement.
4.6InformationQualityTheprocessqualityfactor informationqualitydefinesthedegreeofappropriatenessandusefulnessofinformationsharingfortheteammembersanddecisionmakers(Olivia&Watson,2011).Comparedtointernalteamfactors,informationsharingandqualityhasreceivedfarmoreattentioninS&OPliteratureandresearch(Bower&Fossella,2013;McCormack&Lockamy,2005;Olivia&Watson,2011).Thesharingofinformationtoandamongteammembersisconsideredaprerequisiteforeffectivegroupcollaboration(Hackman,1990).However,littlevalueiscreatedwhentheinformationisoflowquality(Olivia&Watson,2011).Inparticular,theaccuracyofsalesforecastsisfrequentlymentionedasoneofthekeyattributesofS&OPperformance(Mello&Stahl,2011;Stahl&Wallace,2012).Olivia&Watson(2011)witnessedthefosteringofconstructiveengagementthroughinformationsharingintheirqualitativecasestudy.In the quantitative research by Ambrose (2015) a positive relation between information quality andconstructiveengagementisassumed.Thefindingsdidnotsupportthisrelation.However,furthertestingrevealedadirectpositiverelationshipofinformationqualityandS&OPperformance,butitdoesnotflowthroughconstructiveengagement.ThisfindingisinagreementwiththeproposedeffectofinformationqualityontheS&OPprocessqualityassuggestedbyOliva&Watson(2011).Thereforethefollowingfactorandeffectareproposed:Proposed factor and effect: Information quality, which is directly positively affected by constructiveengagement,andhasadirectpositiveeffectonS&OPperformance.

4.7ProceduralQualityTheprocessqualityfactorproceduralqualityreferstotheextenttowhichastructuredandformalizedapproachistakentocollaborativework.Astructuredapproachisidentifiedasanimportantpredictorofgroup effectiveness (Hackman, 1987). Furthermore, support was found for procedural quality as asupportingfactorforcross-functional integration(Nakata&Im,2010).ProceduralqualityhasreceivedconsiderableattentioninS&OPliterature(Ambrose,2015).ExamplesarethedescriptionsofthevariousstagesofmaturityoftheS&OPprocess(Grimson&Pyke,2007;Lapide;2005;Muzumdar&Fontanella,2006;Wagneretal.,2013). However, littlevalidationoftheroleand importanceofthisattributehasbeenprovided(Ambrose,2015).IntheirsingleorganizationcasestudyresearchOlivia&Watson(2011)proposetheattributeproceduralqualityasacriticaldeterminantofS&OPprocessoutcomequality.In the quantitative research by Ambrose (2015) a positive relation between procedural quality andconstructiveengagement isproposed.A significant relationwasnot found, contrary to the research’sexpectationsgiventhefrequentoccurrenceinS&OPliterature(Ambrose,2015;Oliva&Watson,2011).However, a direct association between procedural quality and S&OP performance was supported(Ambrose, 2015). These findings are in accordance with the findings of Olivia &Watson (2011) whoproposeconstructiveengagementcanactuallypositivelyimpacttheproceduralquality,nottheotherwayaround.Thesefindingsareanalogoustothefindingsofinformationalquality.Thisleadstothefollowingproposedfactorandeffectincludedintheresearchmodel:Proposed factor and effect: Procedural quality, which is directly positively affected by constructiveengagement,andhasadirectpositiveeffectonS&OPperformance.
4.8Rewards&IncentivesThefactorrewardsandincentivesreferstotheextenttowhichteammembersarerecognizednotjustfortheiroperational task,butspecifically fortheircontributionstoachievingteam-basedgoals (Ambrose,2015).Jointrewardsareawayoflinkingaworker’sincometooutcomesofcross-functionalteamwork.Aligningrewardsandincentivesisacorepropositionofgroupeffectivenesstheory(Hackmanetal.,2000).The underlying assumption is that joint rewards enlarge the perceived level of interdependence(Chimhanzi,2004).Ambrose(2015)notesmembersoftheS&OPteamonlydevotedafractionoftheirtimetotheactualprocess,andthustheprioritysettingmaybedifficultifnoteam-basedincentivesareinplace.WhilesomeleadingS&OPconsultantsidentifyteam-basedrewardsasasignofS&OPprocessmaturity(Wagneretal.,2013),othersindicatethedifficultiesofchangingrewardsystemstoalignwithS&OP(Grimson&Pyke,2007).Besides,Olivia&Watson(2011)foundintheirsinglefirmqualitativecasesstudy that constructive engagement could be achieved even when rewards and incentives were notalignedwithS&OPobjectives.Infact,thelackofalignmentcouldevenbeidentifiedasfuelforconstructiveengagement,withfunctionalconflictinparticular(Olivia&Watson,2011).InthequantitativeresearchbyAmbrose(2015)apositiverelationbetweenrewardsandincentivesandconstructive engagement is proposed. The findings from the research identified having team-baserewardsandincentivesasthesinglemostcrucialcontextualinfluencerofconstructiveengagementwithinS&OPteams(Ambrose,2015).Duetothis,thefollowingfactorandeffectareproposed:Proposedfactorandeffect:Rewardsand incentives,whichhasadirectpositiveeffectonconstructiveengagement.

4.9Resources&TimeResourcesandtimeisthelastexternalteamfactor.Appropriateresourcesandadequatetimearecriticalfactorsforachievingsuccessfuloutcomesofteamwork(Hollandetal.,2000).InS&OPcontext,resourcesrefertohavingaccesstotrainingandbackgroundinformationabouttheS&OPprocess(Ambrose,2015).Inorganizationswheretimeisscarceduetooverwhelmingresponsibilitieswithinthedepartment,S&OPcanbeviewedasalowprioritydistraction(Stahl,2010).ThecompletionofshorttermtaskisdeemedmoreurgentandeasytograspthanthelonghorizonoftheS&OPprocess(Mansfield,2012).ThiscanleadtothestructuralnegligenceofS&OPmeetings,orfailuretoproperlyprepare(Boyer,2009).PractitionerliteratureexplicitlymentionsstructuralmeetingsasakeysuccessfactorforS&OP(Lapide,2004).AnotherunderappreciatedaspectisthetrainingofteamswithinanS&OPcontext(Ambrose,2015),despitethesuggestedimprovementsineffectivecollaboration(Donnellon,1993).Onelastaspectofresourcesistheavailability of suitable IT facilities. Although general agreement states that sophisticated IT is not anecessity for initial success (Grimson & Pyke, 2007; Wallace & Stahl, 2008), research indicated thattechnology can improve theefficiencyof information sharingand thus improve facilitate constructiveengagement(Olivia&Watson,2011;Wallace&Stahl,2008).InthequantitativeresearchbyAmbrose(2015)apositiverelationbetweenresourcesandtimeallocatedtotheS&OPprocess,andconstructiveengagementoftheS&OPteam.Thefindingsdidnotsupportthisrelationwith significance. Itwas assumed that factors such as developing superordinate identity andaligningrewardsandincentiveshadabiggerimpactonconstructiveengagementthantheavailabilityofresourcesandtime.However,Ambrose(2015)arguesthattheavailabilityofadequateresourcesandtimecanplayanimportantroleintheinitialstagesofS&OPimplementation.Thereforethechoiceismadetoincludethefactorresourcesandtimeinthemodel.Thisleadstothefollowingproposedfactorandeffect:Proposed factor and effect: Resources and time, which has a direct positive effect constructiveengagement.
4.10S&OPPerformanceConstructiveengagementispresumedtoleadtohigherlevelsofcommitmentsandincreasewillingnesstoimplementtheplansresultingfromtheS&OPprocess(Olivia&Watson,2011).Sustainedconstructiveengagement is identifiedbyAmbrose(2015)asacritical factorsforthesuccessoftheS&OPinitiative.Ambrose (2015) defines the following formal definition, which includes aspects of collaboration andfunctionalconflict:“ConstructiveengagementistheextenttowhichS&OPteammembersproactivelycollaborate,includingvoicinganddefendingtheirrespectiveinterpretations.HavingthislevelofengagementisviewedasthelinchpinthatconnectsteamandcontextualinfluencestothedesirableoutcomeofS&OPperformance.”Although empirical research on S&OP performance is scarce, descriptions and indicators of a well-functioningS&OPcanbefoundinpreviousresearch(Ambrose,2015).Reducedfinishedgoodsinventoryismentioned(Dougherty&Gray,2013),aswellasincreasedforecastaccuracy,minimizedsupplychaindisruption,improvedreturnonassets,andincreasedcustomersatisfaction(Wagneretal.,2013).IntheirresearchOlivia&Watson(2011)proposeapositiverelationbetweenconstructiveengagementandthequality of the S&OP process outcomes, flowing through the quality of the S&OP process, includinginformationqualityandproceduralquality.Therefore,thefollowingfactorandeffectisproposedfortheresearchmodel:Proposedfactorandeffect:S&OPperformance,whichisindirectlyandpositivelyaffectedbyconstructiveengagement,flowingthroughProceduralQualityandInformationQuality.

Furthermore,areinforcingstructureis includedintheproposedmodeltomeasuretheeffectofS&OPperformanceonconstructiveengagement.Previousworkhasindicatedhowpositiveprocessoutcomescanleadtoincreasedconstructiveengagement(Keatingetal.,1999;Shibaetal.,1990).IntheplanningprocessqualitymodelbyOlivia&Watson(2011),thequalityoftheS&OPprocessoutcomesissuggestedtoaffecttheperceptionsoftheS&OPteammembers,whichinturnaresuggestedtohaveadirectpositiveeffect on constructive engagement. Ambrose (2015) defines the factor rewards and incentives as theextenttowhichmembersofaS&OPteamreceiverewardsandincentivesbasedonteam-basedS&OPgoals and objectives. This suggests the factor S&OP performance can affect the factor rewards andincentives, which in turn is believed to increase constructive engagement (Ambrose, 2015; Olivia &Watson,2011).Hackmanetal.(2000)identifyaligningrewardsandincentiveswithteam-relatedgoalsasacorepropositioningroupeffectiveness.Peopletendtopursuebehaviorthatisrewarded,andthesameholdsforgroups(Glaser&Klaus,1966).Thislineofthoughtisconfirmedbyscholarswhoacknowledgeagrowingtrendofrewardingworkersbasedonteam-basedgoals,inadditiontoindividualgoals.(Arndtetal.,2011;Bamberger&Levi,2009).However, previous work does not always provide evidence a relation between incentives and theintendedperformanceenhancementsispresent.ArecentstudybyDriedonksetal.(2013)suggeststeam-based rewards positively affects group effort, but a positive effect on overall effectiveness was notsupported.Inadifferentstudy,sharedrewardssystemswerefoundtoimproveinformationsharing,butnottheconnectednessbetweendepartments(Chimhanzi,2004).Furthermore,Grimson&Pyke(2007)acknowledgethedifficultythat isoftenencounteredwhentryingtochangerewardstructurestoalignwithteam-basedS&OPgoals.Still,therewardingofS&OPteammemberstoachieveteam-basedgoalsisadvocated(Singh,2010),andis identified as a sign of S&OP processmaturity (Wagner et al., 2013). Ambrose (2015) describes anexamplehowasalesdepartmentcouldbeincentedtonotonlycareaboutsalesandrevenue,butalsoabouttheassociatedcost,suchasinventoryandscrapcosts.Thisexampleillustrateshowincentivesaimto increasecollaboration. In theworkbyOlivia&Watson (2011) theeffectof incentivesof functionalconflictisdescribed.ItcanbeconcludedmoreresearchisneededtodeterminetheeffectofincentivesoftherelationbetweenS&OPperformanceandconstructiveengagement.TomeasureifS&OPperformanceaffectsconstructiveengagementbasedonthe incentive landscape,thefollowingfactorandeffectareproposedintheresearchmodel:Proposedfactorandeffect:S&OPperformance,whichhasanindirectpositiveeffectonconstructiveengagement,flowingthroughrewards&incentives.

Topmanagement support is alsomentionedasaprerequisiteforgroupeffectivenessandcross-functionalcollaboration(Cohen&Bailey,1997). The research by Ambrose (2015) suggest top management support does not directly affectconstructiveengagement,norS&OPperformance.However,theperceptionspresentedintheinterviewsand theobservations indicate topmanagement supportplaysa crucial role in theS&OPprocess. ThisbecomesmostlyapparentintheavailableresourcesandtimeallocatedtotheimplementationofthenewS&OPprocess.
5.2.5CentralizationInterviewresultssuggestthattheS&OPteammembersperceivedvaryinglevelsofcentralization.Multiplemembersmentionthatdecisionswerealreadymadeinprincipalonahighlevel,andthatonlythefine-tuning was left for the members. However, these viewpoints were more about the implementationprocess,thantheactualS&OPprocess.DuringtheactualS&OPprocessmembersareinfactempoweredtomakedecision.However,whencostsareinvolved,orissuescannotberesolved,topmanagementdoeshavethefinalsayinthesematters.Participant2(S&OPProjectTeam):“SomeformiscentralizationispartoftheS&OPstructure.Themonthlyprocesscontainsasectionwheredecisionsaremade,andwheretopmanagementisinvolved.TheS&OPteamsupportsthesedecisionsbymakingpropositionsandinvestigatingdifferentscenarios.Itispossibletoalignwithintheteamandreachabalancebetweensupplyanddemand.Ifdecisionscanbemadeonthis level itwillhappen.Butwhenalignmentcan’tbereachedorwhencostsareinvolveditwillbeescalatedtohigherlevels.”

Participant9(Sales):“I think themembers in the S&OP process have a certain level of autonomy. Some things have to beescalatedtohighermanagement.Whenfor instancewewanttostart looking into leadtimes,thiswillhave an impact of the inventory levels. This off course has to be informed and accepted by highermanagement.Theconsequencesoflargedecisionsarefeltbythewholeorganization,sotopmanagementshouldbeinvolved.”Observations about the level of centralizationweremostlymade by reviewing the flowcharts of theproposedS&OPprocess.Topmanagementmakesthefinaldecision,andsolves issuesandescalations.However, observations confirmed that the S&OP team is empowered to make decisions.

The findings by Ambrose (2015) indeed showed anegativerelation,meaninghighlevelsofcentralizationarelikelytohaveanegativeimpactonconstructiveengagement.Theopinionspresentedintheinterviews,andtheobservationsdidnotindicatehighlevelsofcentralizationattheresearchorganization.Althoughlargedecisionsandescalationscanbesolvedbyhighermanagement,theS&OPteamhasautonomyandcanmakesmallerdecisions.Inadditiontheyfulfillanimportantroleinpreparingthescenariosanddecisionsthatarepresentedtohighermanagement.

5.2.10S&OPPerformanceSince the S&OP process was not fully implemented at the research organization at the time of thisresearch, it was not possible to report on the S&OP performance improvements. Therefore, theparticipantscouldonlyreporttheirexpectationsaboutwhichperformanceimprovementsthenewS&OPwouldbring.Fromboththeopinionsprovidedintheinterviews,andobservedduringthecasestudyitbecameapparenttheparticipantswereexpectingperformanceresultscloselyrelatedtotheperformancemeasuresoftheirrespectivedepartments.Forinstance,participantsfromthesupplychaindepartmentemphasized the decrease of inventory as an indicator of success, while participants from the salesdepartment indicatedmeasures of success included higher sales, and shorter order fulfillment times.Theseobservationsare in linewith the researchbyOlivia&Watson (2011),who identify the relationbetweentheperceivedbenefitsofparticipating intheS&OPprocess,andtheperceptionoftheS&OPprocessoutcomequality.5.2.11AnalysisofpracticaluseInthissectionthepracticaluseoftheproposedmodelisanalyzed.ThemodeldevelopedinthisthesiscouldbeusedbymanagersduringtheimplementationofaS&OPprocess.Chase(2013)statesnavigatinga successful S&OP journey is 60% change management, 30% process, and 10% technology.

Without top management support it would be impossible to attain the requiredresourcesandtimeforaprocessredesignofthisscale.The two informantsexpects some levelof centralizationwillalwaysbe required in theS&OPprocess.Although the S&OP team is empowered tomake create and propose different scenarios for decisionmaking,theenddecisionsinvolvinginvestmentswillalwaysbemadebytopmanagement.Otherdecisionscan bemadeon lower levels in the organization.Unless issues are escalated to highermanagement,centralizationwillnotdecreasethelevelofconstructiveengagement.InformationqualitywasidentifiedexplicitlybythetwoparticipantsasapotentialriskforthesuccessandoutcomeoftheS&OPprocessredesign.Decisionmakingisbasedontheprovidedinformation.Thismeansthe quality of information will have an important role in the S&OP process.

The input from the exploratoryinterviews,documentation,observationsandtheresultsfromthequestionnairewereusedforthefinalinterviews.Inaddition,thefindingsofthisresearchbymakinguseoftriangulationoutsidetheresearch.ThefindingsfromtheresearchbyAmbrose(2015)wereusedtocompareandvalidatethefindingsofthisresearch.Thesedifferentresearchinstrumentsmayprovidecomplementaryorcontradictoryresults(VanAken et al., 2007). Contradictions occurwhen interviewees act or say something other than they do.Therefore using only a single instrument is likely to yield unreliable results. This thesis research usedtriangulationtominimizetheinstrumentbias.Respondentbiaswasminimizedbyselectingmembersofdifferent functional departments that were affected by the implementation of a S&OP process. Thesecondwaytoreducetheriskofrespondentbiasistousealargenumberofrespondents.Forthisresearchasampleoftenpeoplewasselected.Thebiasofthesituationwasminimizedbycarryingoutthestudyatdifferentmomentintime(VanAkenetal.,2007).Thisallowedtheresearchertomakeobservationsindifferentsituations,andbecomemoreawareofthecontextinthecasestudyorganization.ValidityThethirdmajorcriterionforthequalityofresearchresultsisvalidity.Aresearchresultisvalidwhenthewayitisgeneratedprovidesgoodreasontobelievetheadequatenessandtruthofthefindings(VanAkenetal.,2007).Therefore,arelationexistsbetweentheusedmethodsandthefindings.Thevaliditycriterioncanbebrokendownintothreetypes;constructvalidity,internalvalidityandexternalvalidity(Yin,1994;Swanborn,1996).Theconstructvalidityreferstotheextenttowhichaninstrumentmeasureswhatitisintendedtomeasure.Constructvaliditywasachievedbymakinguseofquestionnairesthathavebeentestedandvalidatedinpreviousresearch.Theinternalvaliditywasachievedbypresentingtheviewsandopinionsofmembersofdifferentfunctionalgroups.Thisdecreasedthechancethatimportantissuesandrelations were overlooked during the research.

Surprisinglyhoweverwas that theanalysis from this thesis researchprovidedasignificanteffect,whilethiswasnotfoundbyAmbrose(2015).Thisresultcanindicatesocialcohesion is a crucial factor to achieve constructive engagement in the early stages of S&OPimplementation.The results from the questionnaires show the respondents perceive high levels of social cohesion. Afriendlyandpositiveatmospherewasobservedduringthecasestudy.Althoughconflictsdidoccur,thesewerecausedbyfunctionalconflict,notpersonalconflict.Boththeinterviews,questionnaireanswersandtheobservationssuggesthigh levelsofsocialcohesiondonothinder,but infact increaseconstructiveengagement. This could reject the claim that high levels of social cohesion stifle critical dialogue assuggested by Janis (1982) and Sethi et al. (2001). In fact, according to a respondent social cohesionprovidedafoundationtohavediscussionsabouttopicsthatwillhaveanimpactonmultipledepartments.This suggest both aspects of constructive engagement, collaboration and functional conflict, can beincreasedbyhighlevelsofsocialcohesion.AchievingsocialcohesionshouldberegardedahighprioritycomponentofaS&OPprocessimplementation.

Although theeffectofsuperordinate identityonconstructiveengagementwas found tobepositive,asignificanteffectwasnotfound.Mediumtohighlevelsofsuperordinateidentityweremeasuredforthefactor superordinate identity. This was surprising as the S&OP process was in the early stages ofimplementationatthetimeofthecasestudy.TheS&OPteamdidworktogetheronaweeklybasis,whichcouldhaveincreasedtheperceptionsoffeelingpartofthesameteam.However, the interviews and observations provide a different picture on the perceived level ofsuperordinateidentity.Althoughtherespondentsvaluetheirpresenceattheteam,indicationsarethattheyfeelmoreconnectedtotheirrespectivedepartments.Duringthe interviewsthefrequencyoftheS&OPprocesswasgivenasanexplanationforthemoderatelevelsofsuperordinateidentity.Thedurationandtheearlystagesof theS&OPprocessat theresearchorganizationdidnotprovideaconclusiveanswer.Thisisexpectedassuperordinateidentityisexpectedtodevelopandgrowovertime.IntheresearchbyAmbrose(2015)asignificantandpositiverelationwasfound,butonlyrespondentswith extendedexperienceparticipated in his research.

isinagreementwiththeobservationswhereconstructiveengagementwasdetected,whilerestrictionsinavailable time and resources were present. The findings of this thesis research suggest constructiveengagement can be achieved despite moderate levels of resources and time being available for themembers of the new S&OP process. This suggestion is of importance to managers, since theimplementationofanewprocesswilloftenaddworkontopoftheregularactivities.Timeandresourcesshouldstillbemanaged,butlowtomoderatelevelsdonotnecessarilyobstructachievingconstructiveengagementduringaS&OPprocessimplementation. ProcessQualityThe variables information quality and procedural quality are grouped under process quality. Thisaggregation is in line with the S&OP process quality model by Olivia & Watson (2011), who foundconstructiveengagementimprovedparticipantperceptionsofinformational,andproceduralquality. Infuturework, additional factors could be added to furthermeasure and define the factors of processquality.Moderatelevelsofinformationqualitywereindicatedbytherespondentinthequestionnaires.Statisticalanalysisdidnotfindasignificanteffectofconstructiveengagementoninformationquality.InaS&OPcontext,salesforecastsinparticulararefrequentlymentionedaskeyindicatorsofinformationquality (Mello& Stahl, 2011; Stahl&Wallace, 2012). In the case study the respondentsweremostlyundecidedaboutthequalityofinformation.ThiscanbeexplainedbytheS&OPprocessattheresearchorganizationbeingintheearlystagesofimplementation.Methodsandprocessesforsharinginformationandsalesforecastswerebeingdevelopedatthetimeoftheresearch.However,expectationswerethatthe increased collaborationdue to the S&OPprocesswould lead to increased information sharing.

However, the positive expectations of respondentsexpressedintheinterviewsareinlinewiththepositiveeffectofconstructiveengagementoninformationquality identifiedbyOlivia&Watson (2011).According toexpectation, informationexchange isunderdevelopmentduringearlystagesofS&OPimplementation.However,thecombinationofcollaborationandfunctionalconflictcouldplayanimportantroleinthedevelopmentofsharinginformationeffectively.Thestatisticalanalysisofthefactorproceduralqualityindicatestherespondentsperceivemoderatetohigh levelsofproceduralquality.Althougha significant relationwasnot found, the findings suggestapositiveeffectofconstructiveengagementonproceduralquality.Despite the S&OP process being in the early stages of implementation, the respondents expressesconfidence in thequality of theprocess.One respondentmentioned thenewprocess shares a lot ofsimilaritiestotheoldprocess.Thetimelineoftheimplementationandthenewroleswerenotfullycleartosomeoftherespondents.Duringthecasestudyconstructiveengagementwasobservedduringthedevelopmentofnewprocess.Bothdimensionsofconstructiveengagement,collaborationandfunctionalconflict,occurredduringworkingsessions.Duringthecasestudytheprocesswasstillpartiallyunderdevelopment.Still, therespondentsalreadyperceivedtheproceduralqualityasmoderatelyhigh.Thiscanbeattributedtothesimilaritiesbetweennew and the previous process, as indicated by one of the respondents.

The findings of the case study suggest the importance of informing and engaging thestakeholdersduringtheearlystagesofS&OPimplementation.S&OPPerformanceFormostmanagerstheperformanceoftheS&OPperformancewillbethemostimportantfactoroftheproposedmodel.Unliketheotherfactorspresentedinthismodelthisisarguablythehardesttoachieve.Manyfactorsgointotheperformanceofthenewlydesignedprocess.Whereasthemanagercanaffecttheotherfactorstosomeextent,S&OPperformanceimprovementarelesslikelytobeachievedwiththeeffortsofonepersonorasmallgroupofpeople.InthismodelS&OPperformancemainlyservesastheoutcomeofprocessquality,asproposedbyOlivia&Watson(2011).InadditiontheS&OPperformanceisproposedtopositivelyaffectconstructiveengagement,flowingthroughalignmentquality.The results from quantitative analysis suggest a positive effect of S&OP performance on rewards &incentives.Thisrelationwasresultedinalowp-valuedespitethesmallsamplesize,providingmotivationforfurtherresearchonthisrelation.IncentivesAlignmentQualityIn the sameway information quality and procedural quality are grouped under the variable processquality, the measured factor rewards and incentives is grouped under incentive alignment quality.AlignmentqualitywasnotpartofAmbrose’sModelofS&OPperformance(2015),thereforeareinforcingstructure fromS&OPperformance toconstructiveengagementwasnot taken intoaccount.However,previousworkprovidedthemotivationtoconsiderthepositiveeffectonconstructiveengagement.TherelationspresentedinthemodelofconstructiveengagementinthisthesisareinlinewiththeproposedmodelofOlivia&Watson (2011). In theirpaper thequalityof theS&OPprocessoutcomespositivelyaffectstheperceivedbenefitsofparticipatingintheS&OPprocess,flowingthroughperceptionsoftheS&OPprocessquality(Olivia&Watson,2011).Inthisthesisincentivealignmentqualityisdefinedasthedegreetowhichtheincentiveslandscapeensuresthegoalsofadepartmentareinlinewiththegoalsoftheorganizationasawhole.Thiscanbeillustratedbytakingthesupplychaindepartmentfromthecasestudyresearchasanexample.Forthisdepartmentreducinginventorylevels,andtheassociatedcosts,isan importantmeasureofS&OPperformance.Thismeasurewasofgreatmeaning to thisdepartment,since these costs were located on the department’s profit and loss (P&L). The perceived benefit ofparticipating in the S&OPprocess,was to lower the inventory costs, and in turn receive rewards andincentiveswhichareattributedtothisperformanceindicator.In the questionnaires the respondents indicated a moderate-low level of the factor rewards andincentives.ThismeanscurrentlytheS&OPteammembersarenotfrequentlyrewardedforteam-sharedresults. Additionally, the respondents were unsure if incentives would be tied to the S&OP processoutcomesinthefuture.Still,quantitativeanalysissuggestapositiverelationexistbetweenrewardsandincentivesonconstructiveengagement.Althoughthisrelationisnotfoundtobesignificant,itisinlinewiththequantitativeresearchbyAmbrose(2015).Infact,intheresearchbyAmbrose(2015)thisfactorwas found tohave the singlebiggesteffecton constructiveengagement.Again, itmustbenoted therespondentintheresearchbyAmbrose(2015)alreadyworkedwithinaS&OPprocessforalongerperiodoftime.TheinterviewswiththemembersoftheS&OPteamprovidedmoreinsightintotheundecidedanswersinthequestionnaires.Answersindicatethecasestudyorganizationdoesnotcurrentlytieanymoney-basedrewardsandincentivesdirectlytoactivitiesintheS&OPprocess.Onerespondentsuggeststheimportanceof the role of non-monetary rewards, such as invitation to certain meetings and access to certaininformation.No rewards directly tied to S&OP activitieswere present at the research organization. However, therespectivedepartmentsoftheS&OPteammembersallhavekeyperformanceindicators.Observations

during the case study showed how misaligned incentives can initiate functional conflict. Theseobservations are in line with the findings of Oliva & Watson (2011), who found out constructiveengagementcanexistdespitemisaligned incentives.The findingsof this researchandtheresearchbyAmbrose(2015)indicatetherewardsandincentivescanhaveadirecteffectonconstructiveengagement.Althoughthereinforcingstructurecouldusemoreresearchinfuturework,thecasestudyhaveprovidedmotivationtobelieveareinforcingstructurecouldexistinaS&OPcontext.TopManagementSupportThefindingsintheresearchbyAmbrose(2015)didnotsupporttheproposedpositiveinfluenceoftopmanagementsupportonconstructiveengagement.However,theroleoftopmanagementsupportshouldnotbediscarded.AsindicatedbythekeyinformantsfromtheS&OPprojectteamresourcesandtimecanneverbe securedwithout topmanagement support. Ina similarway, thedistributionof rewardsandincentivescannotbeapprovedwithouthighlevelsupport.Top management support was perceived as moderate by the respondents in the questionnaires. Apositive,butnotsignificanteffectonconstructivewasfoundduringquantitativeanalysis.Ambrose(2015)suggesttopmanagementcouldbeofparticular importanceduringtheearlystagesofaS&OPprocessimplementation, since during this stage resources and time have to be made available for thedevelopmentandintroductionofthenewprocess.Duringtheinterviewstherespondentsindicatedtheywereundecidedabouttheleveloftopmanagementsupport. However, they did acknowledge the time and resources that were made available for theimplementationofthenewS&OPprocess.Onerespondentindicateswithouttopmanagementsupportthenewprocesswouldn’thavehappened.Thesestatementsareinlinewiththeobservationduringthecasestudy.Althoughtopmanagementwasnotactivelyinvolvedinthedevelopmentandimplementation,adequatetimewasmadeavailablefortheS&OPteam.Althoughasignificantrelationbetweentopmanagementsupportandconstructiveengagementwasnotfoundinthisresearch,findingssuggesttopmanagementdoesplayanimportantroleinthesuccessoftheS&OPprocess.Furtherresearchisneededtoprovidetheconclusivenatureoftopmanagementsupport,andhowitaffectstheotherfactorsintheresearchmodel.Still,sinceanyS&OPprocessinitiativewillclaimtime and resources of the people involved,managers should acknowledge topmanagement supportshould always be secured before initiating any S&OP initiative. Since top management support isrecognizedasthesinglemostimportantdriverofsuccessforanysignificantchangewithinanorganization(Li&Lin,2006),failingtoearnsupportoftopmanagementcouldleadtofailureoftheS&OPinitiative(Milliken,2008).

Conclusion
Thepurposeof thismaster thesis report is to identify the factors affecting constructive engagement,particularlyintheearlystagesofaS&OPprocessimplementation.AnalysisofpreviousworkindicatestheneedforthedevelopmentofacomprehensiveunderstandingofhowS&OPshouldbeimplemented.ThisneedisevidentbythehighpercentageofS&OPprocessimplementationinitiativesthatdonotachievetheintendedresults(Milliken,2008;Wagner,2013).The improved performance associated with implementing a S&OP process is highly dependent onachievingamixofcollaborationandfunctionalconflict,thatisrequiredinacross-functionalteam-basedsettingsuchastheS&OPprocess.Giventhissetting,constructiveengagementis identifiedasacrucialfactorinthesuccessofaS&OPprocess.Anintegratedmodeloffactorsconsideredtoaffectconstructiveengagementisanalyzedquantitativelyandqualitativelywiththehelpofacasestudy.ThefindingsofthiscasestudysuggestthefactorssocialcohesionandcentralizationarecrucialfactorsforachievingconstructiveengagementduringtheearlystagesofaS&OPprocessimplementation.Disputealimitedsample,significanteffectsonconstructiveengagementwereidentified.Whilehighlevelsofsocialcohesionpositivelyaffectconstructiveengagement,centralization reducesconstructiveengagement intheS&OPprocess.Theothersevenfactorsintheproposedmodelwerenotfoundtosignificantlyaffectconstructive engagement. Still, findings from the case study indicate securing the support of topmanagement is identifiedasvital forachievinganyoperationalchanges.Observationsduringthecasestudysuggest informingandengaging thestakeholderscan increase theperceived levelofproceduralquality.The findings of the case study suggest constructive engagement can be achieved despite theabsenceofhighlevelsofresourcesandtime,andrewardsandincentivestiedtooutcomesoftheS&OPprocess.Finally,thefindingssuggestconstructiveengagementcanbepresentdespitemoderatelevelsofsuperordinateidentityandinformationquality.Theempiricaland theoreticalgroundingsof theproposedmodel suggest thepotential formeaningfulimplications for both researchers and practitioners. The internal validity of the research suggest thefindings could be applicable to similar cases. For researchers the model provides the integration ofpreviouswork.Themodelcanserveasthefoundationforadditionalresearchwherefactorsareaddedorsubtractedfromthemodel,basedonfindingsofquantitativeorqualitativeresearch.PractitionerscanbenefitfromthepresentedfindingsfromanorganizationthatwasintheearlystagesofimplementingaS&OPprocess.TheproposedmodelcanserveasaframeworktoidentifythefactorswhichshouldbeincorporatedduringtheimplementationofaS&OPprocess.Duringthecasestudy,respondentsindicatedthefactorsintheproposedmodelcanserveasaguidelineformanagersduringaS&OPprocessimplementationinitiative.Thesmallsamplesizeavailableduringthecasestudyprohibitedconclusivefindings,particularlyintermsofexternalvalidity.Therefore,additionalresearchisrecommendedtofurtherrevealtheroleandrelationsoftheidentifiedfactorsinaS&OPcontext.

Appendix3–Questionnaire
QuestionnaireS&OPMasterThesisStijnMoons
Dear S&OP Team member, for my Master Thesis I am conducting a research study about the S&OP process. With this questionnaire I would like to gain insight into your experiences and opinions about the implementation of the S&OP process at your organization. This includes the changed roles of the Master Scheduler and the Demand Planners. Results from this questionnaire will not be shared with other team members. Your answers will be used as input for a follow-up interview with me. With your answers in this questionnaire and the final interview, I hope to prove the value of implementing the S&OP process at your organization. Since the process has not yet been fully developed and implemented, please answer the question based on your expectations once the process has been implemented. The questionnaire consists of 10 constructs, and will take 10-15 minutes to complete. Thank you! Stijn Moons

There can be little action taken by the S&OP team until upper management approves.
Decisions made purely by the S&OP team would be quickly discouraged by upper management.
Even small matters have to be referred to upper management for a final answer.
We have to ask upper management before we do almost anything.
Any decision that we make as an S&OP team has to have approval from upper management.
