During project implementation, a newly appointed team leader asks the project manager to confirm the team's tasks and schedule. Because the new leader lacks management experience, the work did not go as planned and the project may be delayed. What should the project manager do?

The project manager should provide mentoring to the newly appointed team leader because it addresses the root cause of the problem: the leader's lack of experience. Mentoring helps develop the team leader's skills, enabling them to manage tasks and schedules effectively, which is a proactive and supportive approach to preventing future issues and fostering team growth. Asking HR for a more senior leader is a reactive measure that doesn't address the current leader's development and could demotivate them. Informing the sponsor is necessary if the delay becomes certain, but it's not the first action to prevent it. Taking direct control undermines the team leader's authority and development, and is not sustainable for the project manager.
