Which of the following is NOT an element of a Purchase Request?

A Purchase Request typically includes essential components that facilitate the approval of the acquisition process. Among these elements, a detailed statement of work is critical, outlining the specific requirements needed to fulfill the contract effectively. Funding certification ensures that there are allocated funds available for the procurement, establishing financial responsibility. The contracting officer's signature represents official approval for the request, confirming that due diligence has been conducted and that the request complies with all regulations.

The COR nomination letter, however, is not a fundamental component of a Purchase Request. While the nomination letter may play a role in designating a Contracting Officer's Representative to oversee the contract, it is not directly tied to the request for procurement itself. Therefore, the absence of this letter does not inhibit the purchasing process in the same way that the other elements do. This differentiation highlights why the COR nomination letter does not belong as a required element of a Purchase Request.
