A new project manager is assigned to an agile project and wants to use motivation to sustain team performance throughout the project. What should the project manager do?

Implementing a reward system is a direct and effective way to sustain team motivation and performance. Rewards, whether intrinsic or extrinsic, acknowledge effort and success, encouraging continued engagement. Finding another method to increase performance is vague and doesn't directly address motivation. Using management reserves for team-building activities is inappropriate; management reserves are for unknown-unknown risks, not planned team events. Inflating project estimates is unethical and unprofessional; estimates should be realistic and based on the best available information, not manipulated to create a financial buffer for non-project-related activities.
