In a nutshell Lean and Six Sigma explained
- 2. Lean & Six Sigma are tools used to make improvements in the work place. Lean focus on elimination or reduction of waste. Where as six sigma focus on reducing variations LEAN & SIX SIGMA
- 3. The business process map (flow chart) shows the areas where Lean or Six Sigma could be applied in identifying improvements.

- 4. What do we mean by “Lean”? › Waste Reduction › Using “waste walks” in work place › Optimum operating efficiency on machines › Using flow diagrams to achieve improvements. › Mainly in areas where there are machinery and setting up times; Eg. Mould machine set up time.
- 5. Seven Wastes › The waste of over production › The waste of waiting › The waste of transporting › The waste of over processing › The waste of defects › The waste of stock › The waste of motion (between operations)
- 7. Pursuit of eliminating “variations” › Statistical Concept › Benchmark › Goal orientated › Set of tools and techniques
- 8. Voice of Customer › Complaints, rejects, reworks, errors SIPOC Supplier – Inputs – Processes – Output - Customers DMAIC › Define, Measure, Analyse, Improve & Control Statistical process › Data analysis, calculations, charts and graphs to identify improvements.
- 9. Both Lean and Six Sigma are tools within quality assurance to identify improvements in a organisation. Both of these tools are widely used in the manufacturing and engineering sectors to give competitive advantage to companies like Motorola, General Electric and Toyota.
