Process and Dimensional Measurement and Impact of Customer Relationship Management
on Service Quality using Structural Equation Modeling: An Empirical Investigation
Arup Kumar Baksi* & Bivraj Bhusan Parida**
ABSTRACT
Customer relationship management (CRM), as a business process, has transformed the eco-system of firm-
customer relationship from a one-time transactional format to a long-term relationship environment.
Academicians, researchers, practitioners and business analysts pondered over the varied dimensionalities
and process pattern of the CRM system and came out with various propositions, though, CRM performance
(process and dimension driven) as a potential enhancer of service quality, remained as a grey area. This
paper empirically investigates the process and dimensional measurement and possible impact of CRM on
the perceived service quality of customers in the context of banking industry. The paper articulates on
multivariate statistical applications on primary data to test the postulated hypotheses formulated from
review of literatures. The researchers have also used structural equation modeling approach to test the
proposed model involving the three major constructs namely CRM process, CRM dimensions and service
quality. The results revealed a positive and significant impact relationship between CRM process and
perceived service quality with further confirmation of significant moderating effects of CRM dimensions
on CRM process-service quality outcome.

1. Introduction
The emergence of relationship marketing has modified the transactional interface between the
buyer and seller and has evolved as a potential strategic imperative to analyze, interpret, augment
and retain valued customers particularly by the intangibility and heterogeneity dominated service
sector. The application of relationship marketing is valid both for internal as well as for external
customers whereby information exchange and sharing becomes responsive and flexible
(Abdullateef et al., 2010). Customer relationship management (CRM) explicitly recognizes the
long-run value of potential and current customers, and seeks to increase revenues, profits, and
shareholder value through targeted marketing activities directed toward developing, maintaining,
and enhancing successful company-customer relationships. CRM has been conceptualized as a
strategic approach concerned with creation of improved shareholder value through the
development of appropriate relationships with key customers and customer segments (Payne and
Frow, 2005). CRM synchronizes and unites the potential of relationship marketing strategies and
IT [information technology] to create profitable, long-term relationships with customers and other
key stakeholders. CRM provides enhanced opportunities to use data and information to both
understand customers and co-create value with them. This requires a high-degree cross-functional
integration of processes, people, operations and marketing capabilities that is enabled through
information, technology and applications.
Over the last decade or so, CRM has been the key business philosophy with the service sector with
a focal objective to strengthen both external and internal marketing and to detangibilize the service
offer for better quality perception. Barnabas and Mekoth, (2010) were of the opinion that the
modern market-orientation of service firms were more of failure-prevention in nature which they
eventually referred to as hygiene factor. Some of the research findings from hospitality sector
clearly indicate that disposition and behavior of the service provider are crucial in the final
determination of consumer‟s evaluation of the service quality delivered as well as the level of

satisfaction (Reisinger, 2000; Collie and Sparks, 1999). For financial services sector especially for
the banks the application of CRM has been justified (Sobti, 2003). In heterogeneity dominated
service market CRM started providing the firms with competitive edge by ensuring high degree of
customization of services with supportive and meaningful human interactions. CRM, as a business
process, has started gaining strategic attention specifically by the service firms as they considered
the process to have a positive impact on augmentation of perceived service quality.
Although researchers have identified different defining constructs in the area of CRM pertaining
to CRM process and its dimensions (Wang et al., 2004; Sin et al., 2005; Ndubisi et al., 2007;
Chahal and Kumari, 2010; Lo et al., 2010; Basar et al., 2011; Mamoun et al., 2011), there is still
much debate over what exactly constitutes CRM when it comes to dimensionality and process
function (Nevin, 1995; Parvatiyar and Sheth, 2001; Sin et al., 2005; Agariya & Singh, 2012a).
This paper empirically attempts to investigate the nature of relationship between CRM-process
and perceived service quality and the moderating effects of CRM dimensions on CRM process-
service quality outcome in the context of banking industry in India. CRM is gradually picking up
its applications and deployment in Indian banks and is definitely considered as a viable
proposition in providing improved service quality to their customers (Gupta and Shukla, 2002).
Although
2. Review of Literature
Customer relationship management (CRM) marked the end of transaction-based marketing
dominated by marketing mix elements. According to Reinartz et al. (2004), CRM refers to a
systematic strategic process of managing initiation of customer relationship through customer
acquisition process, maintenance of relationship on the basis of symbiotic sharing of value and
profit, and termination of a potentially devalued relationship. Nguyen (2007) defined CRM as a
information system that tracks customers‟ interaction with their firms and enable the firms to
`` SIT Journal of Management

address issues that are potentially inhibitors or enhancers of profitability (Yueh et al., 2010; Aihie
and Bennani, 2007; Adam and Michael, 2005; Gummesson, 2004; Sin et al., 2005). CRM systems
on the other hand, provide the infrastructure that facilitates long-term relationship building with
customers (Hendricks et al. 2007). CRM performance considers delivery of superior customer
value towards building and sustaining competitive advantage (Wang et al., 2004; Ahmad &
Hashim, 2010; Sadeghi & Farokhian, 2010) and facilitates developing relationships with
differentiated customers via interdependent collaboration with those of highest value to the
company (Lowe, 2008; Sadeghi & Farokhian, 2010). Reinartz, Krafft and Hoyer (2004) were of
the opinion that CRM process embodies a systematic and proactive management of relationships
across various touch-points and interfaces related to customer contact channels. Academicians and
researchers, over the years, have focused on developing CRM measurement frameworks (Jain
et.al, 2003, Lindgreen et.al, 2006). While some research works have focused more on IT-related
factors (Avlonitis & Panagopoulos, 2005; Roh, Ahn, & Han, 2005; Wilson, Daniel, &McDonald,
2002), others have emphasized organizational factors like human resources, organizational
structure, and reward systems (Rigby et al., 2002), or business process- related factors (Campbell,
2003; Payne & Frow, 2004; Reinartz, Krafft, & Hoyer, 2004). Studies were also made to link
CRM components and their performance output, namely, linking customer satisfaction with
business performance (Kamakura et al. 2002), the linking customer loyalty with firm profitability
(Reinartz and Kumar 2000), heterogeneity in customer profitability as an output to CRM
deployment (Niraj, Gupta, and Narasimhan 2001), and exhibition of customer loyalty as a
behavioural function to CRM adoption (Verhoef 2003). Literatures revealed a few take on CRM
performance measurement based on CRM process and dimensionality ((e.g., Brewton &
Schiemann, 2003; Jain, Jain, & Dhar, 2003; Kim, Suh, & Hwang, 2003; Lindgreen et al., 2006;
Zablah, Bellenger, & Johnston, 2004). Lindgreen et.al, 2006, proposed a CRM assessment tool
comprising of three categorical elements namely strategic elements (customer and brand strategy),
infrastructural elements (culture and people) and process elements (relationship-management
`` SIT Journal of Management
Vol.2. No. 2. December 2012. Pp.90-121

process). While researchers continued to focus on tangible and quantitative key performance
indicators (KPI) such as revenue generated, customer acquisition, retention and defection rates,
time to execute services including service recovery process, cost optimization etc., to explain the
success/failure of a CRM system, Jain et.al (2003) explored into the behavioural dimensions of
CRM that considered the „people‟ element as a pivotal factor. The behavioural dimensions thus
identified were attitude to serve, quality perceptions, understanding the expectations of customers,
reaction time, situation handling capability etc. Abdullateef, Mokhtar and Yousoff (2010)
concentrated on four dimensions of CRM namely customer orientation, CRM organization,
knowledge management and CRM technology to identify caller satisfaction in contact centers.
Ghafari, Karjalian and Mashayekhnia (2011) identified five dimensions of CRM namely
information sharing, customer involvement, long-term partnership, joint problem solving and
technology-based CRM to explore a possible linkage with innovation capabilities of a bank.
Successful implementation of CRM requires synergistic synchronization between four identified
dimensions namely focusing on key customers, organizing around CRM, managing knowledge,
and incorporating CRM-based technology (Yim, Anderson and Swaminathan, 2004). The
dimensions of CRM are supposed to influence the CRM process which focuses on value creation
resulting in manifested behavioural intention of the customers. Reinartz, Krafft, & Hoyer, 2004,
concluded that successful implementation of CRM process is associated with enhanced firm
performance. Other researchers have also explored CRM process frameworks from diversified
point of views namely service profit chain (Heskett et al., 1994), return on quality (Rust, Zahorik
and Keiningham, 1995), customer asset management (Berger et al., 2002), customer equity
(Blattberg, Getz and Thomas, 2001; Rust, Lemon and Zeithaml, 2001). Review of literature also
revealed that there are different methods and categorizations of CRM performance namely
financial versus non-financial, single-dimensional versus multi-criteria, tangible versus intangible
(Chi et al., 2004, Kim et al., 2003, Llamas and Sule, 2004, Payne and Frow, 2005).

Community and retail banking system has evolved as a major domain of CRM application. As
banks automated back-office functions with mainframes, and the number of products and services,
particularly related to cross-selling and up-selling activities, grew, banks found it increasingly
necessary to introduce and replace its branch-based filing cards with a Central Information file
(CIF). Panda and Parida (2005) have identified the key drivers of CRM in retail banking which
has been categorized under two factors: (i) Internal factors (ii) External factors. The drivers are
presented in Table-1 below:

The pursuance of CRM by firms, particularly in the service sector, has been strongly focused on
augmentation in the perception of service quality leading to favourable behavioural intention
namely customer retention, attitudinal loyalty and repatronization (Swift, 2001). Service quality
has been recognised as a critical prerequisite and determinant of competitiveness for establishing
and sustaining long-term satisfying relationships with customers (Wang & Wang, 2006) which
inevitably reinforces the philosophy of CRM. A number of studies were targeted towards
revealing the global attributes of services that significantly contribute to quality assessments in
conventional service environment (Gronroos, 1982, 1984; Parasuraman et al., 1985, 1988). Over
the years, exploration to enhancement of service quality has remained as the focal research object

(Yavas et.al., 1997, Rust and Zahorik, 1993; Cronin and Taylor, 1992, 1994; Buttle, 1996; Crosby
and Stephens, 1987; Parasuraman et.al. 1988; Kearns and Nadler, 1992; Avkiran, 1994; Julian and
Ramaseshan, 1994; Lewis, 1989, 1993; Llosa et.al., 1998). Grönroos (1982) described service
quality as a customer‟s perception of difference between the expected service and the perceived
service. The study of service quality was pioneered by Parasuraman, Zeithaml and Berry (PZB),
who developed the gaps framework in 1985 and its related SERVQUAL instrument in 1988
(Parasuraman, Zeithaml and Berry [PZB] 1985, 1988, 1991). Numerous researchers have also
highlighted the independent effect of perceptions on service quality evaluations and have
questioned the use of disconfirmation paradigm as the basis for the assessment of service quality
(Carman, 1990; Bolton & Drew 1991a, Babakus & Boller, 1992; Cronin & Taylor, 1992. A
number of scholars were of the opinion that service quality can be represented by a dual-
dimension process (Grönroos, 1984; Lehtinen and Lehtinen, 1982). The first dimension deals with
what the service actually delivers and is referred to by PZB (1985) as “outcome quality” and by
Grönroos (1984) as “technical quality”. The second dimension deals with the delivery process of
the service. PZB (1985) described it as “process quality” while Grönroos (1984) termed it as
“functional quality”. Parasuraman, Zeithaml and Berry (1991) defined service quality as “the
degree and direction of discrepancy between customers‟ service perceptions and expectations”.
One of the results of the studies initiated by Parasuraman, Zeithaml and Berry (1985) was the
identification of ten determinants of service process quality namely responsiveness, competence,
access, courtesy, communication, credibility, security, knowing the customers and tangibles.
Review of literature confirmed that although studies were made to identify the dimensionality,
components and process of CRM, there is an absolute dearth in research to link CRM dimensions
and process with service quality, particularly with respect to intangibility & heterogeneity
dominated service sector. This paper, therefore, empirically explores the link between CRM
process and dimensions with perceived service quality. Our approach to identify and quantify the
CRM process and dimensions supplements the CRM dimensional frameworks reviewed and

Following „introduction‟ the layout of the paper follows: „review of literature, model construct and
hypothesis formulation, methodology, data analysis and conclusion including future research and
limitations.
3. Model construct and hypothesis formulation
Appropriate to the literature reviewed, we propose the following model (Fig.-1); depicting the
probable impact of CRM dimensions and process on perceived service quality. We have used
„CRM initiation‟, „CRM maintenance‟ and „CRM termination‟ as the CRM process elements as
was successfully used by Reinartz, Krafft, & Hoyer, (2004); „customer orientation‟, „CRM
organization‟, „knowledge management‟ and „CRM technology‟ as the CRM dimensions
(Abdullateef, Mokhtar and Yousoff, 2010); and service quality dimensions as identified by
Parasuraman , Zeithaml and Berry (1985,1988,1991).

Fig.1: Proposed model based on review of literature
The researchers intend to explore the possible link between CRM process and service quality
owing to the dearth of research focus in this area. Accepting retention as the thematic philosophy
of CRM, the researchers further expect a significant and positive associationship between CRM
process and service quality as satisfied and retained customers are a result of superior service
quality (Varki and Colgate, 2001; Ranaweera and Neely, 2003;) and service quality is a potent
antecedent to customer satisfaction (Cronin et al., 2000). Accordingly it is hypothesized that:
H1: Superior perceived service quality (PSQ) is associated with enhanced implementation of CRM
process at its various stages (initiation, maintenance and termination)

Customer orientation has been considered to be a pivotal dimension of CRM (Yueh et al., 2010;
Sin et al, 2005; Yim et al, 2005) and so was CRM organization or organizational alignment of
CRM process been considered to be a important dimensions by the researchers particularly when
studies were undertaken to explore the linkage between CRM organizational alignment and
organizational performance and profitability based on delivery of superior service quality (Black
and Boal, 1994; Miller, 1996). Harnessing and managing knowledge about customers have proved
to be a significant dimensional input for enhanced service quality and long-term customer
relationship (Roland and Werner, 2005; Dean, 2007; Antonio et al., 2005). The success of CRM
process has also been accounted to the degree to which a firm has made justified technology
integration. Several existing literatures have argued in support of the positive impact that CRM
technology had on perceived service quality (McNally, 2007; Wang et al, 2006; Ravipa and Mark,
2004; fox and Stead, 2001). In the following study the researchers intend to explore the
moderating effects of CRM dimensions on perceived service quality which led to hypothesize that:
H2: Superior customer orientation will lead to stronger and positive relation between CRM
process and perceived service quality (PSQ).
H3: Greater level of CRM organizational alignment will ensure stronger and positive link between
CRM process and perceived service quality (PSQ).
H4: Greater degree and efficiency of managing customer knowledge will ensure stronger and
positive link between CRM process and perceived service quality (PSQ).
H5: Greater degree and efficiency of technology integration will ensure stronger and positive link
between CRM process and perceived service quality (PSQ).
4. Methodology
The objectives of the study were (a) to explore the impact relationship between CRM process
elements and service quality dimensions (b) to assess the moderating effects of CRM dimensions

on CRM process-service quality outcome and (c) to test the proposed model (Fig.1) using
structural equation modeling. The study was carried out in the banking sector involving the largest
public sector bank of India namely State Bank of India (SBI) across 5 cities in West Bengal
(Asansol, Durgapur, Ranigunj, Andal and Bolpur) involving 14 branches. The study was
comprised of two phases. Phase-I involved a pilot study to refine the test instrument with
rectification of question ambiguity, refinement of research protocol and confirmation of scale
reliability was given special emphasis (Teijlingen and Hundley, 2001). FGI was administered
among 20 respondents representing assorted demography and originated from different
geographical locations. The structured questionnaire thus obtained after refinement contained four
sections. Section-I asked the external respondents (customers) about their perception of service
quality as offered by their bank (SBI), section-II was intended to generate response from the
internal customers (employees) with regard to CRM process initiated by their bank (SBI), section-
III was designed to generate response across the CRM dimensions from the internal customers
(employees) and section-IV focused to collect demographic data of the respondents. The
SERVQUAL scale developed by Parasuraman, Zeithaml and Berry (1985, 1988) was used with
adequate modification to generate response about customers‟ perception of service quality. Three
CRM process elements were used namely CRM initiation (15 items), CRM maintenance (20
items) and CRM termination (4 items) (Reinartz, Krafft, & Hoyer, 2004). Four CRM dimensions
were identified for the study namely customer orientation (4 items), CRM organization (5 items),
knowledge management (5 items) and CRM technology (5 items) following a number of
literatures reviewed. A 7 point Likert scale (Alkibisi and Lind, 2011) was used to generate
response. The second phase of the cross-sectional study was conducted by using the structured
questionnaire. Systematic simple random sampling technique was administered as every fifth
customer coming out of the bank premise was requested to fill-up the questionnaire. A total
number of 2000 questionnaires was used which generated 1558 usable responses with a response
rate of 78.00% (approximately). A total number of 70 bankers were also interviewed for section-II
`` SIT Journal of Management

and section-III of the questionnaire. Exploratory factor analysis (EFA) was employed using
principal axis factoring procedure with orthogonal rotation through VARIMAX process with an
objective to understand the factor loadings/cross loadings across components across SERVQUAL
response. Cronbach‟s α was obtained to test the reliability of the data, Kaiser-Meyer-Olkin (KMO)
was done for sample adequacy and Barlett‟s sphericity test was conducted. Structural equation
modeling approach using Lisrel 8.80 was used to test the research model.

Exploratory factor analysis (EFA) was used to test reliability of the SERVQUAL instrument. The
Cronbach; s Coefficient alpha (.926) was found significant enough across the five dimensions and
therefore it are reasonable to conclude that the internal consistency of the SERVQUAL instrument
used was adequate. The KMO measure of sample adequacy (0.901) indicated a high-shared
variance and a relatively low uniqueness in variance (Kaiser and Cerny, 1979). Barlett‟s sphericity
test (Chi-square=1987.127, p<0.001) indicated that the distribution is ellipsoid and amenable to
data reduction (Cooper and Schindler, 1998).
The exploratory factor analysis with principal component analysis and varimax rotation didn‟t
justify the „Assurance‟ dimension due to very low factor loadings/cross loadings (<0.500) and
poor reliability (Cronbach‟s‟ s alpha 0.266). Therefore the assurance dimension was discarded for
the study. The modified SERVQUAL had the items related to technology usage in the banks, the
augmented processes concerning service delivery, cross-selling and up-selling integration with the
core baking service which scored considerably and consistently high in terms of factor loadings
and cross loadings was also found to be significant i.e. >0.700 (significant as per
recommendations of Nunnally, 1978). These items loaded in a specific component across all the
four metros were nomenclated as „Convenience‟. The five dimensions of service quality thus
retained to obtain the perception score from the respondent were: (i) Tangibles (4 items), (ii)
Reliability (5 items), (iii) Convenience (6 items), Empathy (4 items) and Responsiveness (3 items)
(Table-3). Application of exploratory factor analysis, has therefore, reduced the 33 item scale into
a 22-item scale.

Index construction for CRM process components was done based on formative indicators
(Diamantopoulos and Winklhofer, 2001) as our constructs represented composite individual
indicators across different components. The critical issues identified by Diamantopoulos and
Winklhofer, 2001, with regard to successful construction of indexes with formative indicators
namely (a) content specification, (b) indicator specification, (c) indicator collinearity, (d) external
validity and (e) nomological validity were considered and found to be justified with the construct.
Bivariate correlation was obtained to understand the relationship between service quality
dimensions and CRM process elements and the results (Table-4) confirmed a strong and positive
relationship between the same: tangibles with CRM initiation (r=.618**, p<.001), CRM
maintenance (r=.726**, p<.001) and CRM termination (r=.452**, p<.001); reliability with CRM
initiation (r=.349**, p<.001), CRM maintenance (r=.052*, p<.005) and CRM termination
(r=.848**, p<.001); convenience with CRM initiation (r=.163**, p<.001), CRM maintenance
(r=.104**, p<.001) and CRM termination (r=.112**, p<.001); responsiveness with CRM initiation
(r=.056*, p<.005), CRM maintenance (r=.084**, p≤.001) and CRM termination (r=.100**,
p<.001) and empathy with CRM initiation (r=.332**, p<.001), CRM maintenance (r=.527**,
p<.001) and CRM termination (r=.198**, p<.001).

To conduct the regression analysis, we constructed the CRM initiation, CRM maintenance and
CRM termination by weighted multiplication of the individual indicators with the standardized
PLS weights as was successfully used by Reinartz, Krafft, & Hoyer, 2004.
The model specification is depicted as a equation below with the variables grouped into major
effects (βs), moderation effects (γs) and control variables (δ).

We hypothesized (H1) that perceived service quality is influenced by CRM process elements and
that the superiority of service quality can be linked to enhanced degree of CRM process
implementation. Results as tabulated in Table-5 confirmed that for PSQ (expectation) CRM
initiation (β1=.231**, p≤ .01) and CRM maintenance (β1=.697**, p≤ .01) exhibited strong and
positive significance whereby PSQ (perception) has been supported by all the three process
elements: CRM initiation (β1=.110**, p≤ .01), CRM maintenance (β1=.579**, p≤ .01), CRM
termination (β1=.091*, p≤ .05). Our hypothesis-2 (H2) considered that customer orientation would
have a moderating effect on CRM process-PSQ outcome. H2 was strongly and positively

supported for initiation and maintenance process both in case of PSQ (expectation): initiation
(γ1=.289**, p≤ .01), maintenance (γ1=.366**, p≤ .01), PSQ (perception): initiation (γ1=.257**, p≤
.01), maintenance (γ1=.299**, p≤ .01), and marginally for termination process, PSQ (expectation):
termination (γ1=.093*, p≤ .05) and PSQ (perception): termination (γ1=.104*, p≤ .05). Our
hypothesis-3 (H3) considered that CRM organization would have a moderating effect on CRM
process-PSQ outcome. H3 was strongly and positively supported both in case of PSQ
(expectation): initiation (γ1=.333**, p≤ .01), maintenance (γ1=.698**, p≤ .01) & termination
(γ1=.197**, p≤ .01) and PSQ (perception): initiation (γ1=.431**, p≤ .01), maintenance (γ1=.321**,
p≤ .01) & termination (γ1=.221**, p≤ .01). Our 4th hypothesis (H4) considered that knowledge
management would have a positive moderating effect on CRM process-PSQ outcome. H4 has been
supported strongly and positively for maintenance process (γ1=.099**, p≤ .01), marginally for
initiation (γ1=.045*, p≤ .05) and not supported at all by termination process in case of PSQ
(expectation). H4 received strong to marginal support for PSQ (perception) in case of initiation
(γ1=.216**, p≤ .01), maintenance (γ1=.109**, p≤ .01) & termination (γ1=.071**, p≤ .05)
respectively. Our final hypothesis (H5) assumed that CRM-technology would exhibit a positive
and moderating effect on CRM process-PSQ outcome. H5 was strongly and positively supported
both in case of PSQ (expectation): initiation (γ1=.601**, p≤ .01), maintenance (γ1=.471**, p≤ .01)
& termination (γ1=.119**, p≤ .01) and PSQ (perception): initiation (γ1=.412**, p≤ .01),
maintenance (γ1=.201**, p≤ .01) & termination (γ1=.216**, p≤ .01). The R2 value for Model-2
(PSQ-perception) measured .52 indicating that CRM-process elements & CRM dimensions
(independent variables) measures 52.00% of the variation in perceived service quality (perception)
which was considered to be significant enough for predictability of the model. Thus hypotheses H1
to H5 were confirmed and accepted.
Confirmatory factor analysis was used to understand the dimensionality, convergence and
discriminant validity for each construct to determine whether all the 80 items (including
SERVQUAL, CRM-process elements and CRM dimensions) measure the construct adequately as

they had been assigned for. LISREL 8.80 programme was used to conduct the Structural Equation
Modeling (SEM) and Maximum Likelihood Estimation (MLE) was applied to estimate the CFA
models. A number of fit-statistics (Table-6) were obtained. The GFI, AGFI and NFI scores for all
the constructs were found to be consistently >.900 indicating that a significant proportion of the
variance in the sample variance-covariance matrix is accounted for by the model and a good fit has
been achieved (Baumgartner and Homburg, 1996; Hair et al, 1998, 2006; Hulland, Chow and
Lam, 1996; Kline, 1998; Holmes-Smith, 2002, Byrne, 2001). The CFI value for all the constructs
were obtained as > .900 which indicated an acceptable fit to the data (Bentler, 1992). The RMSEA
values obtained are < 0.08 for an adequate model fit (Hu and Bentler, 1999). The probability value
of Chi-square is more than the conventional 0.05 level (P=0.20) indicating an absolute fit of the
models to the data. The Cronbach‟s α values were consistently >.700 and hence the scale is
reliable (Nunnally and Bernstein, 1994). The factor loadings considered for the model is >.600 and
items having <.600 factor loadings were eventually discarded.

Structural Equation Modeling (SEM) was used to test the relationship among the constructs. A
number of fit-indices (Table-7) namely Chi-square/df = 459.98/79, GFI = 0.981, AGFI = 0.957,
CFI = 0.955, NFI=0.961, RMSEA=0.042, expected cross validation index (ECVI)=0.921 were
found to be significant. All the 55 paths drawn were found to be significant at p<0.05. The
research model holds well (Fig.2) as the fit-indices supported adequately the model fit to the data.

6. Conclusion
The objectives of the study was threefold (a) to explore the impact relationship between CRM
process elements and service quality dimensions (b) to assess the moderating effects of CRM
dimensions on CRM process-service quality outcomes and (c) to test the proposed model
involving the three major variables using structural equation model.
The data analysis provided support to conceptualize that the CRM process (comprising of three
elements) has been instrumental in influencing the perceived service quality of the customers.
Therefore adoption and subsequent implementation of CRM philosophy by State Bank of India
(SBI) was justified as the bank can expect greater degree of customer loyalty and profitability
owing to such pro-customer strategy. The information gathered from the bankers with respect to
CRM process and CRM dimensions revealed that SBI is poised to ensure strategic gains from
CRM deployment and the CRM framework has been adopted rather well. The analysis further
revealed that the CRM dimensions, particularly CRM organization and CRM technology has
strong and positive effect on CRM process-service quality outcome confirming and justifying the
upgradation and automation of SBI in technological and behavioural front. Thus CRM process-
service quality link is more likely to produce positive-synergistic results if SBI continues to
emphasize on differentiated training programme for their employees, motivate pro-customer
attitude in their employees and maintaining profitable customer touch-points. Investment made in
CRM technology (specifically the automation done through the implementation of CBS in SBI
and allied IT infrastructure) was also justified as it assured a strong and positive impact on CRM-
process – service quality relationship. Customer orientation of SBI also revealed a positive impact
on perceived service quality. The study suggested an improvement in the knowledge management
aspects of the bank. Lastly, the study also confirmed the significant constructs of CRM process,
perceived service quality (PSQ) and CRM dimensions on the structural model. The researchers
`` SIT Journal of Management

believe the model can be used by the bankers for continuous upgradation of CRM process and
CRM dimensions, with addition/deletion/modification of components to ensure a higher degree of
perception of customers towards service quality. The model can also be used to identify possible
reasons for customer defection also.
The study had geographical limitations as it has been restricted to some restricted places of West
Bengal, which in future, can be widened to obtain a more generalized conclusion. Further
extrapolations can be made by considering the behavioural impact of CRM-process-service quality
interaction. The study can be taken up for other service sectors also, particularly hospitality and
tourism industry which thrives on CRM. The study was cross-sectional in nature; therefore
longitudinal research may be taken up also to realize the gradual changes of CRM process-CRM
dimensions and perception of service quality over time.
