Integrated Master Plan (IMP)
EVM Terms
Reviewed by forProject Technology - updated Sep 2026
Quick definition: The Integrated Master Plan (IMP) is an event-based project plan: a hierarchy of events, each supported by accomplishments, with each accomplishment tied to criteria that show it's complete.
The IMP is organized around significant events rather than calendar dates. It's normally incorporated into the contract, so it's contractually binding rather than just an internal planning tool. Its events, accomplishments, and criteria are carried down into the detailed schedule, the Integrated Master Schedule (IMS).
What this means for you
Because the IMP is event-driven rather than date-driven, it keeps a project focused on what must actually be accomplished before moving forward, not just on hitting a date on the calendar. That reduces the risk of declaring an event "done" prematurely just because a deadline arrived.

FAQ
How is the IMP different from the IMS?
The IMP is the higher-level plan of events, accomplishments, and criteria. The IMS is the detailed Network Schedule that carries it out.
Is the IMP a required document on every contract?
No. It's common on larger government programs and in some agencies, but whether one is required depends on the contract.
