According to the PMBOK Guide, project managers need to adapt their approach and style to the changing environment and needs of the project1. When a project management office (PMO) is incorporating more adaptive technologies, such as agile or hybrid methods, the project manager and the project team need to acquire the necessary knowledge and skills to apply them effectively2. One of the ways to do this is to set up a training session for all project team members, where they can learn the principles, practices, and tools of the new methodology, and how to update the project artifacts accordingly3. This would help to improve the team's performance, as well as their engagement and collaboration. The other options are not as effective as providing training, as they do not address the root cause of the problem, which is the lack of understanding and adoption of the new methodology. References:
