The best option for the project manager in this situation is to provide mentoring to the newly appointed team leader. Mentoring is a process of using experienced members of the organization to provide personal support and guidance to less experienced members of the staff. Mentoring can help the team leader to develop the necessary skills and competencies to manage the team effectively, to overcome challenges, and to achieve the project goals. Mentoring can also foster a positive and collaborative work environment, where the team leader and the team members can learn from each other and share feedback. The project manager can use various techniques and tools to mentor the team leader, such as setting clear expectations, providing regular coaching, giving constructive feedback, sharing best practices, facilitating problem solving, and recognizing achievements. The other options are not as effective as option D. Option A is not feasible, as it may not be possible to find a senior team leader who is available and willing to take over the project. Option B is not proactive, as it only reports the problem, but does not offer any solution. Option C is not empowering, as it undermines the team leader’s authority and responsibility, and may create resentment and demotivation among the team members. References: (Professional in Business Analysis Reference Materials source and documents)
