Who is designated and authorized in writing by the contracting officer to perform specific technical or administrative functions?

The contracting officer's representative (COR) is the individual specifically designated and authorized in writing by the contracting officer to perform particular technical or administrative functions related to contract management. The responsibilities of the COR include overseeing the contractor's performance, ensuring compliance with contract terms, and acting as a liaison between the contractor and the government organization.

Being authorized in writing highlights the formal nature of this role; it sets clear boundaries and responsibilities, ensuring that the interplay between the contracting officer and the COR is structured and accountable. This formal designation is vital in maintaining the integrity and oversight of contract execution.

The other roles mentioned, while integral to the contracting process, do not specifically encompass the authority to perform the tasks assigned to the COR. The contracting officer holds overall responsibility and authority, the contracting specialist usually focuses on the execution of the contractual process, and acquisition team members may contribute different expertise but do not have the designated oversight role that the COR does.
