According to the Project Management Body of Knowledge (PMBOK), one of the key responsibilities of a project manager is to ensure that lessons learned from previous projects are applied to current projects. This helps to avoid repeating the same mistakes and to leverage successful strategies. In this scenario, the project manager should share the lessons learned from the previous project with the team member. This will not only help to resolve the current issue more efficiently but also contribute to the team member's learning and development.
