Project Management Professional Practice Question

The correct answer is a detailed procurement Statement of Work (SOW). The SOW provides a narrative description of the products, services, or results to be supplied. It is the most crucial document for communicating the project's specific needs, including deliverables, requirements, and acceptance criteria, to potential vendors. This ensures all vendors base their proposals on the same detailed information, leading to accurate and comparable bids. A project charter is too high-level, a stakeholder register is for internal analysis, and the risk register, while important, does not primarily define the work for suppliers.
