The Plan is alive...
It’s almost funny in a tragic sort of way how many project managers seems to think a project plan is a one-time event in the project. It isn’t. It is a continious task through out the project. As the project progresses, a bright project manager ajusts the plan so it fits the actual project progress. If the project plan isn’t updated, there might be selveral reasons. Updating the plan maybe causing a headace and take hours and hours.
