The initial step for a COR when there is a need for a contract change is to:

Identifying and documenting the change is the essential first step for a Contracting Officer's Representative (COR) when there is a need for a contract change. This process involves thoroughly understanding the nature of the change, the rationale behind it, and how it impacts the existing contract's terms. Accurate documentation is crucial because it provides a clear basis for any further actions that may follow, such as notifying the contractor or seeking necessary approvals from higher authorities.

Moreover, well-documented changes serve as a reference for both the COR and the contractor, helping to ensure that all parties have a mutual understanding of the modifications required and the reasons for them. This documentation also supports any future negotiations and official modifications to the contract, ensuring compliance with regulations and contractual obligations. By laying this groundwork, the COR can effectively manage the change process and communicate it appropriately to all stakeholders involved.
