The portfolio management plan is intended to:

The portfolio management plan serves as the governing framework that defines how portfolio management will be conducted, setting direction through its articulation of approach and governance structures. It aligns the entire portfolio management effort with strategic objectives by defining who does what, how decisions are made, and what principles guide the work.

While authority levels are addressed in the plan, option B's description covers only a subset of the plan's scope and omits the critical link to organizational strategy that defines the plan's primary purpose.

Documenting scenarios and environmental factors describes elements of portfolio analysis or risk planning, not the primary intent of the portfolio management plan itself.

Process-related assets from stakeholders and teams describe organizational process assets, which are inputs to portfolio management, not the purpose of the portfolio management plan.
