Which of the following is a key role of a COR during contract performance?

A key role of a Contracting Officer Representative (COR) during contract performance is facilitating communication between parties. This responsibility is vital because effective communication ensures that expectations are aligned, issues are promptly addressed, and any concerns regarding contract execution are managed proactively. The COR serves as a bridge between the contractor and the government, helping to clarify requirements, relay contractor updates, and ensure that both parties have a mutual understanding of progress and any challenges that may arise.

Facilitating open lines of communication can lead to stronger relationships and enhance collaboration, which is crucial for the successful delivery of contract services. Monitoring the contractor's performance and providing timely feedback are also part of this communication role, ensuring that any performance deviations are identified and rectified quickly.

The other options highlight important functions in contract management but are not core responsibilities of a COR during contract performance. Independent audits are typically conducted by external auditors, writing contracts falls under the purview of contracting officers, and making financial decisions is usually managed by finance or budget personnel rather than the COR.
