A project using a hybrid approach has three sprints remaining. A team member informs the project manager they are leaving the company, and the functional manager has approved the departure. What should the project manager do first?

The project manager's first action should be to review the risk management plan and mitigation plan. This is a critical step in risk response, as the departure of a team member is a known risk that should have been identified and planned for. Understanding the pre-defined impact and mitigation strategies allows the project manager to assess the situation systematically and determine the best course of action. Asking for an immediate replacement is premature without understanding the full impact and existing mitigation strategies. Asking the functional manager why the decision was made is unproductive and doesn't address the immediate project need. Persuading the team member to stay is generally ineffective, unprofessional, and unlikely to succeed once a departure has been approved.
