Establish a formal process for documenting lessons learned during the execution of projects. These documents should be visible to all and easily accessible for later analysis.
Analyze each project’s performance in the three constraints, stakeholder satisfaction, or other important metrics after it is completed.
Use the 5 Why technique to identify root causes for negative points like those in #2. These root causes can be analyzed statistically to determine their frequency and correlation with the negative points. Also, estimate the cost/time required to find potential solutions.
Select solutions should be implemented on a beta-test with one or more projects. It is important to clearly define the points where the process differs from the firm’s standard methodology.
Analyze the results of these specific changes in the beta projects.
Based on the results of beta testing, make changes to the common method.
Rinse and Repeat.
