Six Sigma Analyze Tollgate Review
A Six Sigma Analyze phase Tollgate Review is like a checkpoint at which the various team members meet with a project Champion and determine whether the work has been performed as indicated in the project plan and whether the objectives mentioned have been achieved.
A Tollgate Review will help you determine if the goals in a DMAIC stage have been completed and whether you can move on to the next stage.
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 hypothesis, and alternative hypothesis been developed for the data analyzed
Quantifying the Gap/Opportunity
- What is the cost of poor quality (COPQ) as supported by the team’s analysis?
- 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)?
Analyze Stage Deliverables
- Revised Charter problem statement reflecting an increased understanding of the problem
- Additional Sources of Variation are statistically quantified and prioritized
- Use and display Multi-Vari tools to identify and verify the “Vital few” (Knob Variable) factors
- Graphical analysis and interpretation of data using Basic Quality Tools
- Correlation and Regression Analysis (if Applicable)
- Hypothesis statement(s), null hypothesis and alternative hypothesis has been developed for the data analyzed
- Hypothesis test output, p-value, and interpretation of the data
- Any red flags with the project or project scope and recommendations to resolve
- Red flags and recommendations for resolving them defined
- Next steps documented
- Approval of report out signed by Project Champion
