Failure Modes and Effects Analysis (FMEA) (Qualitative Analysis)
- Has the Preliminary FMEA been developed?
- Has the Team drilled down on at least the five Key Inputs determined through the C&E Matrix
- Has the team discovered any quick wins from the FMEA? If so, how are they being dealt with?
Quantitative Analysis
- What Statistical Tools were used to analyze the data?
- Has the team gathered data for a Mult-Vari Analysis to determine the “Critical Few” Variables?
- Has the team used the Basic Quality Tools to graphically analyze the data?
- Has a Hypothesis statement(s), null hypothesisHypothesis testing definition A statistical hypothesis test ... Learn More..., and alternative hypothesisHypothesis testing definition A statistical hypothesis test ... Learn More... been developed for the data analyzed

- What are the revised rough order estimates of the financial savings/opportunity for the improvement project?
- Have the problem and goal statements been updated to reflect the additional knowledge gained from the analysis phase?
- Have any additional benefits been identified that will result from closing all or most of the gaps?
- What were the financial benefits resulting from any ‘ground fruit or low-hanging fruit’ (quick fixes)?
