  1. Six Sigma Introduction

  2. WHAT IS SIX SIGMA? • Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services – as defined by our customers. • Why ”Sigma“? The word is a statistical term that measures how far a given process deviates from perfection. • The central idea behind Six Sigma is that if you can measure how many “defects” you have in a process, you can systematically figure out how to eliminate them and get as close to “zero defects” as possible.

  3. KEY CONCEPTS OF SIX SIGMA Critical to Quality: Defect: Attributes most important to the customer. Failing to deliver what the customer wants. Process Capability: Variation: What our process can deliver. What the customer sees and feels. Stable Operations: Ensuring consistent, predictable processes to improve what the customer sees and feels.

  4. SIX SIGMA ─ ELEMENTS OF QUALITY Three key elements of quality: customer, process and employee. Delighting Customers: In every attribute that influences customer perception, we know that just being good is not enough. Delighting our customers is a necessity. Because if we don’t do it, someone else will! Outside-In Thinking: Quality requires us to look at our business from the customer’s perspective, not ours. With this knowledge, we can identify areas where we can add significant value or improvement from their perspective. Leadership Commitment: People create results. Quality is the responsibility of every employee. Every employee must be involved, motivated and knowledgeable if we are to succeed.

  5. GAUSSIAN DISTRIBUTION ─ BELL CURVE 68.26% 95.4% Reversal Point 99.74% 2.16% 2.16% 34.13% 34.13% 0.13% 0.13% 13.57% 13.57% -4 -4 -3 -2 -1 0 -1 -2 -3 Number of standard deviations of average value To achieve Six Sigma quality, a process must produce no more than 3.4 defects per million opportunities.

  6. THE SIGMA-LEVEL Measuring Method to Determine Process Performance The higher the value, the more efficient the process

  7. SIX SIGMA AND CX • Our Customers Feel the Variance, Not the Mean • Often, our inside-out view of the business is based on average or mean-based measures of our recent past. Customers don’t judge us on averages, they feel the variance in each transaction, each interaction. Six Sigma focuses first on reducing experience and process variation and then on improving the process capability. • Customers value consistent, predictable business processes that deliver world-class levels of quality. This is what Six Sigma strives to produce.

  8. BREAKTHROUGH-STRATEGY SIX SIGMA(Optimal Improvement) STANDARD METHODS(Gradual Improvement) BREAKTHROUGH-IMPROVEMENT • GRADUAL IMPROVEMENT: • Kaizen • Re-Engineering • TQM • Current Tools and Approaches IMPROVEMENT QUOTA DURATION IN YEARS 1 2 3 4 5

  9. SOURCES FOR SIX SIGMA PROJECTS The Following Methods are Applied DMAIC DFSS – DESIGN FOR SIX SIGMA Improvement of existing processes(DMAIC-Cycle: Define, Measure, Analyze,Improve, Control) Creating new products and processes (DMADV-Cycle: Define, Measure, Analyze, Design, Verify) CHANGE MANAGEMENT PROJECT MANAGEMENT Tools to initiate, support and control the necessary alteration processes Coordination and implementation of all initiated projects. Due to state of the art development tools companies operate faster, more individual, more rational

  10. SIX SIGMA – SUCCESS FACTORS Increase of Company Value through Customer Satisfaction and Customer Loyalty Customer Loyalty through implementation of critical improvements based oncustomer demands Evaluation + improvementof customer’s satisfaction> DMAIC-Process Detect + fulfill future important customer requirements> DFSS View through rearview mirror View through front window SIXSIGMA DESIGN FOR SIX SIGMA

  11. DMAIC-CIRCLE / DMAIC-CYCLE DMAIC-Cycle to Measure Current Projects and Their Improvement IMPROVEMENT AND SUSTAINMENT Implementation of solution approach, monitoring, controllingand documenting WHAT IS THE PROBLEM Problem description and definition of project objective; initiation of project and planning of milestones ANALYZE MEASURE IMPROVE CONTROL DEFINE SOLUTION Selection of solution alternatives and implementation of a strategy to reach goals SEVERITY OF THE PROBLEM Determination of causes for actual problems and cause variables, quality, data and facts REASONS Processing of the results and problem analysis

  12. DEFINE – DEFINITION PHASE Tasks of the Six Sigma Champion 1 Preparation of project charters 2 Focus on customer requirements and company interest 3 Securing of sufficient project resources within the team (commitment of all participants) 4 Strict separation from other projects 5 Consideration of economical value, probability of success and availability of resources

  13. PROJECT ORGANIZATION AND ROLES Description of roles and related skills CONTROL CIRCUIT CHAMPION MASTER BLACK BELT BLACK BELT GREEN BELT YELLOW BELT Experienced senior project manager; management of cross-sectional strategic projects Project manager and Coach; executes projects together with other business divisions Leads projects within his sector of responsibility; implementation of smaller Six-Sigma projects Part of the project team, which applies Six Sigma methods; supports execution of projects Responsible for budget and resources; sponsor of Six Sigma projects TEAM MEMBER

  14. THREE IMPLEMENTATION APPROACHES COMPANY WIDE STRATEGY IMPROVEMENTPROGRAM IMPLEMENTATION IN TOP-DOWN-PROCESS Management makes decisionson the introduction of Six Sigma, which are transferred to all company levels USE POTENTIALS Internal improvement initiative, to use improvement potentials within the day-to-day routine of the company TOOLBOX 7X7-TOOLBOX Success by integration of selected improvement tools from the 7x7-Toolbox (mixture of techniques, methods and mental models)

  15. RECAP – WHAT IS SIX SIGMA? INDICATOR OF Efficiency of processes PROCESS IMPROVEMENT Operative and productive processes PROBLEM SOLVING METHOD Systematically , data oriented, (DMAIC-Method, DMADV) CUSTOMER REQUIREMENTS Not quality improvement at all costs QUALITY INITIATIVE Measurable success like increased revenue and lowered costs TOOLBOX Process, analysis, statistics,problem solving strategy
