Because of activity delays, a team member increased the project scope without approval. What should the project manager do next?

The project manager's immediate priority is to understand the implications of the unauthorized scope change. Evaluating the impacts allows the project manager to assess the consequences on schedule, cost, quality, and resources before deciding on a course of action. Removing the changes immediately might be necessary but should follow an impact assessment. Adding team members is a potential solution for schedule delays, but not the first step for an unauthorized scope change. Updating documentation with unapproved changes would legitimize an unauthorized action without proper review.
