Working Principles of Six Sigma – DMAIC, DFSS and DFSS-IDOV
Scenario (a) Requires the Use of DMAIC for process improvement
Define: Process goals in terms of key critical parameters (i.e. critical to quality or critical to production) on the basis of customer requirements or Voice Of Customer (VOC)
Measure: Measure the current process performance in context of goals.
Analyze: Analyze the current scenario in terms of causes of variations and defects DMAIC
Improve: Improve the process by systematically reducing variation and eliminating defects
Control: Control future performance of the process
Scenario (b) focuses on process design using Design For Six Sigma (DFSS) approach. DFSS Approach requires IDOV method
- Identify: Process goals in terms of critical parameters, industry & competitor benchmarks, VOC
- Design: Involves enumeration of potential solutions and selection of the best
- Optimize:Performance by using advanced statistical modeling and simulation techniques and design refinements
- Validate: Design works in accordance to the process goals.
