According to the PMP Exam Content Outline, one of the tasks of a project manager in the leading domain is to
"Empower team members and stakeholders by providing them with the level of authority to complete the assigned activities and resolve issues in order to enhance project performance." This implies that the project manager should empower team members to participate in decision-making and take ownership of actions, especially in megaprojects that involve multiple stakeholders from different geographical areas and cultural backgrounds. Empowering team members can improve team productivity by increasing their motivation, commitment, creativity, and accountability. It can also foster a culture of collaboration, trust, and respect among the diverse team members and stakeholders. Empowering team members can also help the project manager to cope with the complexity and uncertainty of megaprojects, as team members can act more autonomously and responsively to the changing project environment.

Agile project management is a flexible and iterative approach to delivering value to customers and stakeholders. Agile projects are built around motivated individuals who collaborate and communicate effectively, deliver working products frequently, and respond to changing requirements and feedback1. Motivation is a key factor that influences the performance, satisfaction, and retention of agile team members2. According to the agile manifesto, one of the principles of agile project management is to "build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done"3. Therefore, the project manager should implement a reward system that aligns with the agile values and principles, and that recognizes and reinforces the team's achievements, contributions, and behaviors. A reward system can include both intrinsic and extrinsic rewards, such as feedback, recognition, appreciation, autonomy, mastery, purpose, growth, learning, fun, collaboration, innovation, and compensation45. A reward system should be tailored to the needs, preferences, and goals of each team member, and should be fair, transparent, and consistent. A reward system should also be flexible and adaptable, and should be reviewed and improved regularly based on the team's feedback and performance. References:
