Molly is the program manager for her organization and she is creating a program plan that defines the benefits of the program and how her program and team will create the benefits for the organization

The quality management plan defines quality standards, metrics, and processes for ensuring program deliverables meet requirements - it does not define or describe how program benefits will be created or realized.

The business case is a pre-program document that justifies the investment and viability of the program - it is an input to planning but is not itself the plan that manages how benefits are created and delivered.

The program management plan is the overarching planning document covering all aspects of managing the program - it encompasses many subsidiary plans including the benefits management plan, but it is not the specific plan focused on defining and creating benefits.

The benefits management plan specifically identifies the planned benefits of the program, defines how the program's activities and components will produce those benefits, establishes metrics for measuring benefit realization, and assigns accountability for sustaining benefits after program closure. It is created early in the program life cycle and is maintained throughout to keep the program aligned with its value-delivery purpose. This plan is distinct from the broader program management plan because it focuses exclusively on benefit definition and delivery.
