Which of the following is NOT a task for the COR during post-award activities?

The task of creating new contract proposals is not part of the responsibilities assigned to a Contracting Officer Representative (COR) during post-award activities. The COR's role is primarily focused on overseeing the performance and compliance of the contractor with the terms of the existing contract, rather than initiating new contracts.

During post-award activities, the COR is expected to participate in tasks that ensure the contract is executed effectively, such as assessing contractor security, assisting with close-out processes, and maintaining necessary documentation related to the contract's execution and performance. These tasks are critical in monitoring and managing the contractor's work and ensuring that contractual obligations are met.

In contrast, creating new contract proposals typically falls under the jurisdiction of contracting officers or procurement specialists, as it involves the initiation and writing of contracts, which is separate from overseeing and managing existing contracts.
