    • Reduction in cycle-times
    • Improved material management
    • Improved commit process
    • Improved Customer satisfaction
    • Reduction in waste
    • Reduction in defect levels
    • Reduction in WIP and inventories
    • Improved process controls
    • Anywhere performance must improve
    THE IMPACT OF SIX SIGMA 3
  • 5.
    • The Vision
    • is to be a World Class Company
    • with World Class Products
    • and Processes
    VAD R SIX SIGMA? 4
  • 6.
    • The Goal
    • is to reach 6 Sigma in all products
    • and processes as well in the
    • Product Development flow as in the Customer Supply flow.
    • Short term it is to give savings
    • and fulfill the goals of the organization.
    ML 5
  • 7.
    • The Strategy is to use Powerful Statistical tools like:
      • Factorial Experiments (DOE)
      • Regression Analysis
      • Hypothesis Testing
      • SPC and so on
    STRATEGI 6
  • 8. SIX SIGMA CRITICAL 3 FACTOR INTERACTION 7
      • Defining and using metrics that focus our attention on defects that are most important to the customer and have the greatest potential for impacting the bottom line.
      • Dedicated
      • resources trained in the use of the 6 Sigma problem solving methodology.
      • Systematic Approach to reducing defects which affect what is important to the customer (qualitative & statistical).
  • 9. ETABLERA ETT SIX SIGMA IMPLEMENTERINGS OCH LEDNINGSTEAM 8 Site Champions Hands on Champions Master Black Belts Black Belts Management Green Belts Executives & All Employees
  • 10. IDENTIFIERA AFFRSID OCH KRNPROCESSER UTIFRN KUNDENS PERSPEKTIV 9 Processer/ Aktiviteter Kund Behov Kund njdhet S - I - P - O - C Supplier Input Process Output - Customer

BEGIN WITH THE END IN MIND 11 Metrics (Ys) linked to CTQs Problem Statement Project Objective Project Goal PROCESS X 1 X 2 X 3 X 4 Y 1 Y 2 Y 3 Analyze data to determine Root Cause of the Project Problem Identify and validate Improve solution The Ys you select must ultimately assist you in making the breakthrough in improvement to the product or process
  • 12. Processorientering
    • Syfte och ml klarlggs efter kundens frvntningar
    • SIPOC-modell
    • Faktainsamling fr att klarlgga kritiska faktorer
    • Lr dig se analys av vrdefrdlande / icke vrdefrdlande aktiviteter
    • Faststll resurser och mtetal
    • Processgaren utvecklar, frvaltar och frbttrar processen medan linjeorganisationen anvnder den och fljer trender i utfallet mot ml

  • 16.
    • Mer komplexa produkter
    • Snvare toleranser (automatmaskiner)
    • Hgre volymer
    • Mindre felutfall och reparation.
    • Veta mer, tro mindre.

  • 18. AKTIVITETER FR ATT STDJA INITIATIVET 22 Green Belt utbildning fr ett snabbt resultat och engagemang Management utbildning fr comitment White Belt Utbildning fr att all skall frst Black Belt utbildning fr Specialister fr att resultatet skall best Green Belt Utbildning fr att skra initiativet
  • 19. A pragmatic case study in color matching
    • Nya tuffare krav p kulr-matchning gentemot tidigare modeller
    • Kraven specificeras fr kulrmtning enligt CIELAB-standard
    • Mtning sker p:
      • Glans
      • Ljushet (L)
      • Kulrton rtt-grnt (a)
      • Kulrton gult-bltt (b)
    • Fr att kunna faststlla en stabil process mste orsakerna till akut variation elimineras och den kroniska variationen studeras.
  • 20. Lackprojekt - Kulrmtning
  • 21. Genomfrda aktiviteter, Mtsystem
    • Matt, svart yta ger nstan ingen reflektion. En liten variation fr en enskild frekvens i spektrat ger ett stort utslag p mtvrdena i CIE-Lab.
    • Repeterbarhet och kalibrering sker alltid mot vit yta. Vr utrustning har repeterbarhet p E=0,15 fr vit yta.
    • Minoltas bsta utrustning ger inte speciellt mycket bttre vrden p matt, svart yta.
    • R&R oskerhet L=12-36%, a=43-72%, b=16-84%, Glans=25%
    • MSA p pltbricka ger smre resultat n p lock??? Ej tt yta??
    • Inmtning av likare fr varje mttillflle ger kad oskerhet
  • 22. Lackprojekt - Kulrmtning
  • 23. Genomfrda aktiviteter
    • Faktainsamling i styrdiagram
    • Byte av utrustning; matarpump, kompensationsventil, sprutpistol
    • Optimering av utrustning och sprutprogram
    • Frndrad rutin vid frgblandning med mer noggrann uppvgning och omblandning
    • vrstingtest med visuell bedmning fr att avgra nr lackoperatrerna ser frndring
  • 24. Genomfrda aktiviteter; Mankiewicz
    • Leverantrsaudit
    • Saab-godknd 1:a batch
    • Avropsrutin avstmd
