According to the PMBOK Guide, 7th edition, one of the principles of project management is to support team performance. This means that the project manager should foster a collaborative project team environment, build team competencies, and address and remove impediments, obstacles, and blockers for the team. In this scenario, the project manager should provide appropriate training to the team members who lack the necessary skills or knowledge to perform their tasks, rather than emphasizing deadlines, updating the schedule, or accepting the risk. Providing training will help the team improve their performance, deliver value, and meet the expectations of the steering committee and other stakeholders.
