The document discusses various quality improvement concepts including Six Sigma, Kaizen, and their differences. Six Sigma uses a statistical approach to reduce defects through the DMAIC methodology. It aims for near perfect quality levels. Kaizen focuses on continuous incremental improvements involving all employees. While Six Sigma targets reducing variation, Kaizen prioritizes short-term gains through low-cost improvements and group activities like quality circles. Both concepts emphasize top management commitment and aim to enhance customer satisfaction and business performance over the long run.

18. 6 Sigma

19. Six Sigma Was Developed at Motorola in the 1980’s As a Method to Improve Process Quality. It Was First Used to Improve Manufacturing Process Capability and Then Migrated to Business Processes Capability Companies That Have Deployed Six Sigma: Bank of America, Motorola, GE, IBM, Kodak and Many More The Basic Premise Is, All Processes Have Variation. Variation Is the Enemy. About Six Sigma

20. Six Sigma Philosophy Know What’s Important to the Customer (CTQ) Reduce Defects (DPMO) Center Around Target (Mean) Reduce Variation (Standard Deviation) ? GE Company Proprietary November 1998

21. Business Definition A break through strategy to significantly improve customer satisfaction and shareholder value by reducing variability in every aspect of business . Technical Definition A statistical term signifying 3.4 defects per million opportunities. SIX SIGMA-Definitions

22. SIX SIGMA DEFINATIONS 6 σ 3.4 99.9997% 5 σ 320 99.98% 4 σ 6 210 99.4% 3 σ 66 800 93.3% 2 σ 308 000 69.2% 1 σ 690 000 30.9% Your Sigma is… Your DPMO is…. If your yield is…

23. SIX SIGMA-Definitions In brief, Six Sigma is a process control method to improve the quality of products or services in a continuous manner. This method uses six standard deviations of a normal distribution as the limits of customers’ acceptance of the system’s products. This method is applicable to manufacturing as well as service industries. With six sigmas, only 3.4 defects per million are allowed, or an acceptable level of 99.9997% is required

Financial - Bank of America, GE Capital, Electronics - Allied Signal, Samsung, Sony Chemicals - Dupont, Dow Chemicals Manufacturing - GE Plastics, Johnson and Johnson, Motorola, Nokia, Microsoft, Ford. Airline - Singapore, Lufthansa, Bombardier And hundreds of others in Americas, Europe, Sub Continent.

26. Six Sigma Results Six Sigma Savings as % of revenue vary from 1.2 to 4.5 % For $ 30 million/yr sales – Savings potential $ 360,000 to $ 1.35 million. Investment: salary of in house experts, training, process redesign. Annual Savings Company *$1.5 billion (*since inception in 1998) JP Morgan Chase $600 million Honeywell $500 million Johnson & Johnson $ 16 billion (*since inception in 1980s) Motorola $2.0+ billion General Electric

27. Key Concepts of Six Sigma At its core, Six Sigma revolves around a few key concepts. Critical to Quality: Attributes most important to the customer Defect: Failing to deliver what the customer wants Process Capability: What your process can deliver Variation: What the customer sees and feels Stable Operations: Ensuring consistent, predictable processes to improve what the customer sees and feels Design for Six Sigma: Designing to meet customer needs and process capability

28. Dissecting Process Capability Premise of 6  Sources of variation can be: Identified Quantified Eliminated or Controlled Defects Process Capability Inadequate Design Margin Inadequate Process Capability Unstable Parts & Materials Defects Acceptable LSL USL

30. Six Sigma Methodology Control Define Measure Analyze Improve Establish standards to maintain process; Design the controls, implement and monitor. Evaluate financial impact of the project Identify, evaluate and select projects for improvement Set goals Form teams. Collect data on size of the selected problem, identify key customer requirements, Determine key product and process characteristic . Analyze data, establish and confirm the “ vital few “ determinants of the performance. Validate hypothesis Improvement strategy Develop ideas to remove root causes Design and carry out experiments, Optimize the process. Final solutions Project Phases

31. Six Sigma – Case Study Service Organisation Background M/s Alpha Inc. manages out bound cargo from a distribution centre to different stores. Deliveries made on trucks - owned and hired. Customers dissatisfied at delivery schedules. Leadership decision to deploy Six Sigma; Team of 1 Black Belt and 3 Green Belts formed Sponsor of the project – Distribution Manager

32. Define - Critical to Quality (CTQ) Focus on customers generating annual revenue of USD 400,000/-. Current process sigma level - 2.43 or 175889 DPMO Delivery within +/- 1 hour of scheduled delivery time Level 3 CTQ On time delivery to schedule Level 2 CTQ Timely delivery Level 1 CTQ Improved delivery performance Customer needs

33. Define - Goal Statement Reduce number of delayed deliveries by 50 % by 31st December Y 2002 to better meet customer requirement of timely delivery defined as within +/- 1 hour of scheduled delivery.

34. Define - Performance Standards 1 opportunity for a defect per scheduled delivery of freight. No. of defect opportunities per unit Delivery earlier or later than 1 hour. Defect Scheduled time or zero minutes deviation Target LSL = -60 minutes USL= +60 minutes Specification limits Process starts when an order is received Ends when goods are received & signed for at customers desk. Process measurement – Deviation from scheduled delivery time in minutes. Project Y measure Timely delivery Output characteristic A scheduled delivery of freight Output unit

36. Measure and Analyze Driver and Distance identified as key factors influencing delivery performance. Driver selected for focus. Potential root causes as to why Driver influenced the time: Size of the vehicle Type of engine Type of tyres Fuel capacity

37. Experiments designed and conducted using truck type and tyre size. Findings: Larger tyres took longer time at certain routes where area was cramped and time lost in maneuvering. High incidence of tyre failures since tight turns led to stress on tyres thus increasing number of flat tyres. Team modified planning of dispatch process by routing smaller trucks at more restrictive areas. Improve

38. Test implementation. Process sigma level up from 2.43 or 175889 DPMO to 3.94 or 7353 DPMO. Performance still fell short of best in class 4.32 or 2400 DPMO. Improvement led to significant customer satisfaction. Process continually monitored and data on new cycle times, tyre failure collected as per defined methods and frequency, analysed and monitored. Customer satisfaction measured and monitored. Control

39. Key Lessons Learnt Define Difficulty in identifying the right project and defining the scope; Difficulty in applying statistical parameters to Voice of the Customers; Trouble with setting the right goals; Measure Inefficient data gathering; Lack of measures; Lack of speed in execution;

40. Key Lessons Learnt Analyse Challenge of identifying best practices Overuse of statistical tools/ under use of practical knowledge Challenge of developing hypotheses Improve Challenge of developing ideas to remove root causes Difficulty of implementing solutions Control Lack of follow up by Managers/ Process Owners Lack of continuous Voice of the Customer feedback Failure to institutionalize continuous improvement.

41. Key Lessons Learnt “ Define “ ranked most important step but gets the lowest resource allocation Project scoping and its definition is critical to its success/ failure; “ Measure” is considered most difficult step and also gets the highest resources Source: Greenwich Associates Study Y 2002

42. Versatile Breakthrough improvements Financial results focus Process focus Structured & disciplined problem solving methodology using scientific tools and techniques Customer centered Involvement of leadership is mandatory. Training is mandatory; Action learning (25% class room, 75 % application) Creating a dedicated organisation for problem solving (85/50 Rule). What Makes Six Sigma Different?
