Which of the following documents does a vendor rely on MOST before committing funding and resources to a project?

The SOW is a formal document that describes exactly what work is required, including scope, deliverables, schedule, and pricing terms. Vendors review the SOW to determine whether they can meet the requirements and what resources they must allocate. Without the SOW, a vendor cannot accurately estimate effort or cost before making a commitment.

A Purchase Order (PO) is issued after a vendor has already been selected and agreed to work - it is a buyer's authorization to purchase, not a pre-commitment planning document.

SU is not a recognized standard project management document that vendors use to assess resource requirements before committing to a project.

A Memorandum of Understanding (MOU) is a non-binding agreement outlining intent to collaborate but lacks the detailed scope and cost information a vendor needs to commit funding and resources.
