PIR (Post Implementation Review) is an evaluation that takes place after a change or a project has been implemented. Once a change request is made, the review checks if the change and its implementation were successful. It is the analysis of the final working solution that evaluates whether project objectives were met, determines how effectively the project was run, and ensures that the organization gets the greatest benefit from the project
Post Implementation Review helps in answering questions like :
* Has the change solved the problem it aimed to address?
* Did the change impact the customers?
* Were resources allocated effectively through the process?
* Was the change implemented as per the budget?
