In the context of a self-organizing team, it is crucial for the project manager to facilitate an environment where the team can realistically assess their capabilities and commit to deliverables accordingly. This approach aligns with the principles of agile project management, where teams are encouraged to self-organize and make commitments based on their understanding of their capacity and the work to be done. By supporting the team during the planning phase to make feasible commitments, the project manager helps in preventing stress caused by overcommitment. This is supported by the guidance provided by PMI, which emphasizes the importance of team empowerment and realistic commitment to ensure sustainable project progress and team well-being.
