Lessons Learned Handbook:
2. Define performance measures for each lessons learned objective.
Each performance measure should reflect a process. Understanding the
performance measure data and the underlying process is necessary in
order to optimize the lessons learned objective.
Collect Performance Measurement Data:
If data to support the performance measures already exist:
Document source of data and define parameters for sorting.
Review the source of data and clean up anomalies.
Add new parameters to data collection if needed.
If data to support the performance measures does not exist:
Explicitly define data to be collected.
Create consistent and verifiable system to hold data.
Task person(s) to collect data.
3. Analyze the performance measures data for trends and significant changes.
Use Statistical Process Control (or other comparable methods) as the
criteria to determine if trends and changes are occurring or if the data is
If a significant change occurs, determine why. Assess costs of
action vs. inaction, perform corrective action (if the performance
measurement change was negative), perform reinforcing actions (if
the change was positive), or take no action.
If the process is stable, determine if the performance is at an
acceptable, stable value. Criteria to apply:
Risk vs. benefit analysis (Probability Risk Assessment)
Comparison against "benchmark" (other companies, INPO
If a performance change is needed, the PROCESS must be changed.
Study the process and performance measure data.
