A project manager writes to the receiving organization to inform them that all acceptance activities are completed with success and it's time to initiate handover. The receiving manager replies that t

Issuing an internal change request is a detailed step, but informing the sponsor and understanding the broader impact comes first.

While a change request might be needed, the project manager should take responsibility for initial assessment and informing the sponsor, not just delegate the request to the receiving manager.

A two-week delay in handover impacts the project schedule, resources, and potentially costs, constituting a significant deviation from the plan. The project sponsor needs to be immediately informed as they are ultimately accountable for the project's success and timeline. Following this, the project manager must actively replan activities to mitigate the impact of this delay, such as reassigning resources or adjusting the final closure tasks, to minimize overall project prolongation.

Delivering on time when the receiving team isn't ready would lead to an unsuccessful handover and potentially a lack of adoption or proper functioning of the project deliverables.
