During the project, a key resource asks whether the project's purpose aligns with the organization's strategy. Which document should the project manager share with that resource?

The benefits management plan describes how and when the project's benefits will be delivered and measured, directly linking the project to organizational strategy. Sharing this document will clarify the project's purpose and its strategic alignment for the key resource. The project management plan is a comprehensive document but doesn't specifically detail strategic alignment as its primary purpose. The communications management plan outlines how project information will be communicated but not the strategic rationale itself. The scope management plan defines how the project scope will be managed and controlled, not the strategic benefits.
