After assessing the project team's performance, the project manager finds some team members performed poorly on their tasks. What should the project manager do?

The best approach is to develop different strategies tailored to each team member's motivation and ability. Performance issues can stem from various factors, including lack of skill, lack of motivation, or external obstacles. A "one-size-fits-all" approach is often ineffective. By understanding individual needs, the project manager can provide targeted coaching, training, or motivational support, leading to improved performance. Creating a new standard performance measure is not the immediate solution; the issue is current performance against existing measures. Developing a standard approach for feedback, while good practice, doesn't address the underlying reasons for poor performance. Providing intensive oversight might be necessary in some cases but can also be demotivating and doesn't solve the root cause of the performance problem.
