  1. Lean Six Sigma Overview

  2. Lean Six Sigma Overview Definition Six Sigma is a fact-based, data-driven philosophy of quality improvement that values defect prevention over defect detection (ASQ). Lean The ultimate goal of Lean is to provide perfect value to the customer through a perfect value creation process that has zero waste. The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources.

  3. Lean Six Sigma Overview Lean Efficiency Improvement

  4. Lean Six Sigma Overview Six Sigma Quality and Efficiency Improvement

  5. Six Sigma Lean Lean Six Sigma Combining Lean and Six Sigma is Best in Class

  6. Lean Six Sigma Overview Six Sigma Business Focused Customer Focused Process Focused

  7. Views of Lean Six Sigma Business Strategy Benchmark Goal Six Sigma Methodology Philosophy Process Measurement Tools Project

  8. Lean Six Sigma Overview Six Sigma as a Business Strategy links the outputs of a company processes to customers requirements. Customer satisfaction can be increased by reducing waste and process variation. This can result in improving operating margins.

  9. Lean Six Sigma Overview Benchmark The Sigma value can be used to Benchmark performance.

  10. Lean Six Sigma Overview Goal The goal of Six Sigma is have the highest level of performance possible. • At the 6 Sigma level there is 3.4 DPMO • 99.9997 % defect free product or service

  11. Lean Six Sigma Overview 6 Sigma 3-5 Sigma 3 Sigma 1-2 Sigma

  12. Lean Six Sigma Overview Methodology Six Sigma as a Methodology, provides a structured, step by step process of assessing and resolving variation in processes which is accomplished completing the following stages: • Define • Measure • Analyze • Improve • Control This process focuses on cause and effect, using numerous analytical problem solving tools, supported by a management structure.

  13. Lean Six Sigma Overview Define “Identify customer requirements” Control “Monitor new processes” Measure “Measure current performance” DMAIC Analyze “Identify root causes for performance defects” Improve “Identify and implement solutions”

  14. DMAIC PHASES Champion/ Process Owner Identify Problem Area

  15. DMAIC PHASES Determine Appropriate Project Focus Define Estimate COPQ Charter Project

  16. DMAIC PHASES Stability, Capability, and Measurement Systems Measure Identify and Prioritize All X’s

  17. DMAIC PHASES Analyze Prove/Disprove Impact X’s Have on the problem

  18. DMAIC PHASES Identify, Prioritize, Select Solutions to Control or Eliminate X’s causing Problems Improve Implement Solutions to control or Eliminate X’s Causing Problems

  19. DMAIC PHASES Implement Control Plan to control or Eliminate X’s causing Problems Control Verify Financial Impact

  20. Lean Six Sigma Overview Philosophy Six Sigma as a Philosophy is based on the premise that a process will yield a greater return if the variation in process output is reduced to stay within limits defined by the customer. The philosophy is one of continuous improvement, using data and various algorithms to reduce process variation Meeting the customer expectations will realize gain in competitive advantage. There is a positive correlation between Six Sigma Program & Process Performance.

  21. Lean Six Sigma Overview Process measurement As a Process Measurement system, Six Sigma uses data to analyze process performance and find Root Causes of defects. The following calculations are use when assessing defects and root causes: • Defects • Defects per unit (DPU) • Parts per million (PPM) • Defects per million opportunities (DPMO) • Rolled Throughput Yield (RTY) • First Time Yield (FTY) • Sigma Value

  22. Lean Six Sigma Overview Six Sigma as a Project Practical Problem Statistical Solution Results Control Plan Six Sigma Project Statistical Problem Practical Solution

  23. Lean Six Sigma Overview Six Sigma as a Project Practical Problem Chronic problem impacting on the success of a process. Six Sigma Project Six Sigma is used to quantify the problem and output expectation. Statistical Problem The quantified problem is evaluated with facts and data analysis

  24. Lean Six Sigma Overview Six Sigma as a Project Statistical Solution Results Data driven solution is found Measurable results with quantifiable financial or strategic value. Control Plan Method is developed for long- term sustainability of the solution Practical Solution Develop ready to implement Practical solution

  25. Lean Six Sigma Overview Six Sigma uses specific tools to solve business problems. These tools are used to map processes, select projects, analyzed data and identify solutions. These tools include but are not limited to: • Pareto Chart • Fishbone diagram • Prioritization Matrix • Histogram • Control Chart • Failure Mode and Effect Analysis • Root Cause Analysis

  26. Lean Six Sigma Overview Process: Sequence of interdependent and linked procedures which, at every stage, consume one or more resources to convert inputs from suppliers into an outputs of value to the customer. Output Input Process Action

  27. Lean Six Sigma Overview Work Process Work Process Output Input Process

  28. Lean Six Sigma Overview Improvement Process Improvement Process Input Process Output

  29. Lean Six Sigma Overview Every process has a dependent variable Y that can be influenced by independent variables Xs. Understanding the relationship between the Xs and Y is the goal of Lean Six Sigma. When this relationship is understood, manipulation of the Xs can be carried out in such a manner so that Y remains within the appropriate range, meeting customer requirements. Y = f(X¹, X², X³ ………….Xⁿ)

  30. Lean Six Sigma Overview Y = f(X¹, X², X³ ………….Xⁿ) Y X

  31. Lean Six Sigma Overview Variation • Lean sigma focuses on variation • All repetitive activities have a certain amount of variation • Variation is the “Voice of the Process” • Input, Process and Output measures have variation.

  32. Lean Six Sigma Overview Critical to Quality (CTQ) A Defects: Service Unacceptable to customer Product or Service Output VARIATION

  33. Lean Six Sigma Overview Sigma σ Sigma is a Greek letter that is used to represent a statistical unit of measurement to define the standard deviation of a population. It measures the variability or spread of the data. It indicates how much of the data falls within the customer’s requirement – the higher the sigma, the more the process outputs, products and services, meet customers’ requirement. The higher the process sigma, the fewer the defects.

  34. Lean Six Sigma Overview Critical to Quality (CTQ) B A Defects: Service Unacceptable to customer Product or Service Output VARIATION
