This third phase of the DMAIC Project is all about analyzing the root causes of the problem. The deliverables of the Analyze phase are straight forward: Have you verified the root causes and quantified their impact? Then you are done. In reality, this phase is the heart of any DMAIC project. Here is where the detective work is conducted, no stone is left unturned and facts get on the table. Several statistical tools come into use here.
- Verified root causes
- Quantified impact of root cause on project metrics
- Process Mapping
- Waste Analysis
- Cause and Effect Diagram
- Relationship plots (Stratified Frequency Plots, Scatter Plots, Multi-Vari Charts)
- Hypothesis tests
- Regression Analysis
- Design of Experiments
