What is a Benefits Sustainment Plan?

A benefits sustainment plan is the document that defines how the benefits delivered by a program will be maintained, measured, and protected after the program closes and responsibility passes to the operational organization. It is the bridge between the end of program delivery and the long-term realization of value.

It typically identifies who owns each benefit after handover, what metrics will track ongoing benefit performance, what conditions might cause a benefit to erode, and what actions the receiving organization should take if performance falls below expectations.

This plan is distinct from the benefits realization plan — which focuses on delivering the benefits during the program — and from the benefits transition plan — which covers the handover itself. Sustainment is about what happens after the handover is done.

For the PgMP exam, if a question describes operational staff struggling to maintain expected outcomes after program closure, the root cause is typically a weak or missing benefits sustainment plan.
