After a client requests a new feature, what should a project manager do if the request would disrupt the schedule?

The most appropriate course of action when a client requests a new feature that could disrupt the schedule is to proactively communicate. Communication is vital in project management, especially regarding changes that may impact the project's timeline, scope, or resources. By engaging in proactive communication, the project manager can discuss the implications of the requested change with the client, including potential delays, resource allocation, and the ability to deliver existing commitments on time. This approach helps in managing client expectations and ensuring that everyone is aligned regarding project priorities and timelines.

Updating the project timeline is certainly a necessary step if the change is approved, but the immediate action should focus on open dialogue with the client to inform them of the possible impacts of their request. Understanding the client's needs and engaging them in the decision-making process can lead to more informed and effective project management.
