  1. 1. Using Six Sigma Tools Define Measure Analyse Improve Control
  2. 2. Lean Use Lean to create flow and bring problems to the surface Current State Future State
  3. 3. Define Understand the Problem Define the Problem e.g. • High failure rates • Missed targets • Long lead times • High scrap rates • Excessive waiting times • High scrap rates • Expediting
  4. 4. Six Sigma Use Six Sigma Problem Solving techniques to make process improvements
  5. 5. Measure Measure the problem • For example, reduce waiting times by 50% • Achieve consensus Where are we now? Where to would we like to be? • Use Numbers (averages, variation +/-) • Control Charts • Check Sheets • Histograms
  6. 6. Analyse Use careful analysis to identify causes • Cause and Effect or Fishbone Diagrams • Pareto Charts • 5Y’s
