Lean Six Sigma Improvement Approach
- The Lean Six Sigma Improvement Approach is used to improve
existing processes.
- The five phases of DMAIC help you to understand the problem and
the customer needs, gather the data, uncover the root causes, fix the process, and make sure it stays fixed.
- Most business problems can be solved using this structured approach.
Clearly define the problem; gather the Voice of Customer; map
the process at a high level; determine potential project value
Gather the data to determine the actual performance (baseline); map the value stream; perform a process risk assessment; measure waste and Cost of Poor Quality; implement Quick Wins
Use data and statistics to identify and validate root causes; perform Value analysis to uncover bottlenecks, delays and other waste
Implement improvements targeted to root causes; eliminate waste and variation; demonstrate measurable improvement (practically
and statistically)
Ensure sustainability of the process; measure stability using Statistical Process Control, Standard Work and visual management
