To pinpoint and verify causes
Documentation of potential causes
Identification of value-add and non-value-add work
Calculation of process cycle efficiency
Conduct value analysis. Identify value-add, non-value-add and business non-value-add steps ( see definitions on p. 50).
Calculate Process Cycle Efficiency (PCE). Compare to world-class benchmarks to help determine how much improvement is needed.
Analyze the process flow.
Identify bottleneck points and constraints in a process, fallout and
Analyze data collected in Measure.
Narrow the search. Use brainstorming, selection, and prioritization techniques (Pareto charts, hypothesis testing, etc.) to narrow the search for root causes and significant cause-and-effect relationships.
Collect additional data to verify root causes. Use scatter plots or more sophisticated statistical tools (such as hypothesis testing, ANOVA, or regression) to verify significant relationships.
Prepare for Analyze gate review.
Calculations of Process Cycle Efficiency
Where process flow problems exist
Root Cause Analysis
Documentation of the range of potential Key Process Input Variables (KPIVs) that were considered (such as cause-and-effect diagrams, p. 146; FMEA, p. 270)
Documentation of how the list of potential causes was narrowed (stratification, multivoting, Pareto analysis, etc.)
Statistical analyses and/or data charts that confirm or refute a cause-and-effect relationship and
Documentation of which root causes will be targeted for action in Improve (include criteria used for selection)
Updated charter and project plans
Team recommendations on potential changes in team membership considering what may happen in Improve (expertise and skills needed, work areas affected, etc.)
Revisions/updates to project plans for Improve, such as time and resource commitments needed to complete the project
Team analysis of project status (still on track? still appropriate to focus on original goals?)
Team analysis of current risks and potential for acceleration
Plans for the Improve phase
