Post Project Reviews are generally done at the end of any significant project or portion of a project. A project that runs longer than a year may conduct Post Phase Reviews at the each of each significant phase, for example, so that lessons are captured while they are still easily recalled. This process might be used with a project that completed some time ago, but for which the lessons were not gathered.
The project review process is the most effective mechanism for improving project management practices and actual project results. A timely, comprehensive review of project performance can reveal so much. This Project Review Survey is a complete resource for project performance feedback and analysis.
