Which of the following is a way the government communicates requirements to a vendor during a source selection?

• A. Memo to Proposers
• B. Statement of Work (SOW)
• C. Verification Matrix
• D. Technical Manual

Answer: (B)

The Statement of Work communicates the government's requirements in detail to vendors during source selection, including the scope of work, tasks to be performed, deliverables, performance standards, schedule, and acceptance criteria. By laying out what is expected in a clear, contractually binding format, it allows vendors to prepare proposals that meet those exact needs and provides the basis for evaluating those proposals. A memo to proposers is typically used for clarifications or administrative instructions during the procurement process, not to define the work itself. A verification matrix maps requirements to tests and verification methods used later, not for initial requirement communication. A technical manual describes operating or maintenance instructions for a product, not the procurement requirements vendors must meet.
