What is the default method of communication between a COR and a contractor?

Written communication is recognized as the default method of communication between a Contracting Officer Representative (COR) and a contractor because it provides a clear, formal, and legally binding record of all interactions. Documentation is essential in a contracting environment, not only for compliance and accountability but also for ensuring that all parties have a mutual understanding of requirements, expectations, and agreements.

Written communication minimizes the risk of misunderstandings, as it allows for thorough detailing of instructions, modifications, and any issues that may arise during the performance of the contract. This method facilitates tracking communications over time, which can be critical for audits, performance reviews, and resolving disputes.

Other forms of communication, while they may be useful in certain circumstances, do not provide the same level of formality or record-keeping. For example, verbal communication can be subject to misinterpretation and lacks the permanence of written documentation. Informal emails and text messaging could be considered too casual for significant contractual discussions, and they may not always be retained for record-keeping purposes, which can lead to gaps in the communication history. Thus, the preference for written communication is vital in a contracting context to uphold standards of clarity and accountability.
