The project manager should first consider organizing paired work sessions for the junior and senior economists. This is a proactive and positive way to address the issue of intimidation and improve the performance and confidence of the junior economist. Paired work sessions can also foster collaboration, knowledge sharing, and mentoring among the project team members. This option aligns with the PMI-PBA practice guide, which states that "pairing a less experienced analyst with a more experienced one can be an effective way to transfer skills and knowledge" (p. 44). The other options are not the best choices because they do not address the root cause of the problem and may have negative consequences for the project.
Evaluating the performance of the junior economist in the upcoming months (option A) is a reactive and delayed approach that does not provide any immediate support or guidance to the junior economist.
Reassigning some of the junior economist's tasks to other economists (option B) may reduce the workload of the junior economist, but it does not help him or her overcome the intimidation or develop the skills and knowledge needed for the project. Requesting to replace the junior economist with a more experienced economist (option C) may seem like a quick and easy solution, but it may also demoralize the junior economist, disrupt the project team dynamics, and incur additional costs and risks for the project.
