1. Using Six Sigma Tools
Define
Measure
Analyse
Improve
Control

2. Lean
Use Lean to create flow and bring problems to the surface
Current State
Future State

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. Six Sigma
Use Six Sigma Problem Solving
techniques to make process
improvements

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. Analyse
Use careful analysis to identify causes
• Cause and Effect or Fishbone Diagrams
• Pareto Charts
• 5Y’s

7. Improve
Implement Countermeasures
• Create implementation plan (Ghant chart)
• Plan, Do, Check, Adjust

8. Control
Verify Improvements
• Check Lists
• Control Charts
Act to Sustain
• Controls, e.g. standardisation, visual displays etc
