Lean and Six Sigma
- Lean is an approach that seeks to improve flow in the value stream and eliminate waste. It is about doing things quickly.
- Six Sigma uses a powerful framework (DMAIC) and simple to advanced statistical tools to uncover root causes of the problem to understand and reduce variation. It is about doing things right (defect free).
- Lean is an approach based on the removal of waste from service and manufacturing processes. Many companies have reported significant improvement through the removal of waste or non-value added activities.
- Six Sigma improves quality through defect removal and process optimization. The improved quality leads to higher perceived value and increased market share thereby, increasing revenue and achieving higher profitability. Many companies have reported significant savings by reducing the cost of poor quality.
