If a project manager has a suggestion based on personal experience as to improving the methodology, there should be a process in place to do so. Any proposed change should have a clear correlation to a problem that needs to be solved. The continuous improvement process should not be left up to volunteer suggestions, however. It should be a part of the methodology and how the business runs a project.
I can suggest a skeleton process:
- Establish a formal process by which lessons learned are documented regularly while executing projects, and put in a format and location where they are visible to all and can be later analyzed.
- After each project is finished, analyze the project in terms of performance in the triple constraints, stakeholder satisfaction, and other metrics important to your organization.
- For negative points identified in #2, use the 5 Why technique to document root causes. Do some statistical analysis on these root causes to determine their frequency, correlation to the negative points identified, and the estimated cost/time involved with potential solutions.
- Implement selected solutions on a beta test with one or a few projects, clearly defining the points at which the test process diverges from the firm's common methodology.
- Analyze the results in the beta projects of these specific changes.
- Based on the successes or failures of the beta testing, implement changes in the common methodology.
- Rise and repeat.
You may notice that the skeleton process above fits within Deming's Circle. That is:
- Plan - 1-3
- Do - 4
- Study - 5
- Act - 6
