the Evaluate phase provides a mechanism for constantly improving the organization’s IT investment process. The goal of this phase is to measure, analyze, and record results based on the data collected throughout each phase. Senior executives assess the degree to which each project has met its planned cost and schedule goals and has fulfilled its projected contribution to the organization’s mission. The primary tool in this phase is the post-implementation review (PIR), which should be conducted once a project has been completed. PIRs help senior managers assess whether a project’s proposed benefits were achieved and also help to refine the IT selection criteria to be used in the future.
