A post-project appraisal is carried out to determine the success of meeting project objectives and delivery of benefits. A comparison is made between the risks and impacts that occurred during the project life-cycle and those anticipated at the business case stage. The optimism bias with reference to the business case should be assessed. The lessons and results of the post-project review should be placed in a database for future reference.
Performing post-project reviews, which record the things that worked well, those that could be done better and those that failed altogether, can be of immense benefit to future projects.
