Many project products should be re-examined after a period of use to check the achievement or not of the benefits expected. For example, when you implement a business process reengineering project you will have to wait for a few months after the completion of the project in order to identify e.g. whether the administrative costs have been reduced and the productivity has been increased. Similarly, when you run a project for the expansion of the railway network you have to wait a year or more in order to realize whether the number of passengers served by it is increased and the traffic in the respective highways and roads has been diminished.
If this is the case, a recommended date should be defined for conducting the post project review. Besides a plan should be prepared which should define the following:
| ● | What benefits will be measured (Note: These benefits should have been previously defined in the Business Case) |
| ● | How the achievement of these benefits will be measured (Note: Usually the achievement of the benefits is measured using Impact Indicators, that have been established during the Planning Phase (refer to 7.4.9) |
| ● | Who will carry out the measurements (it is not necessary to name certain individuals but you could describe the required skills). |
