Which document is issued to notify unsuccessful bidders?

The correct choice of "Notification of Non-Award" serves a crucial function in the procurement process by formally informing bidders that they were not selected for a contract award. This document not only communicates the decision but can also provide feedback and maintain transparency in the selection process. It helps ensure that unsuccessful bidders understand why they were not chosen and allows them to address any deficiencies in future bids.

In the context of procurement ethics and communication, this notification fosters good relationships and transparency between the contracting agency and the bidders. It is important for maintaining trust and encouraging future competitive engagements from those bidders.

Other documents mentioned, such as the Letter of Award, Contract Modification, and Delegation Letter, serve different purposes. The Letter of Award is issued to inform successful bidders about their selection, while a Contract Modification refers to changes made to an existing contract. A Delegation Letter typically involves the assignment of authority but is not related to the notifications pertaining to bid outcomes. Thus, those documents do not fulfill the specific requirement of notifying unsuccessful bidders, which is the primary role of the Notification of Non-Award.
