Explanation This answer is based on the knowledge area of project cost management, which involves planning, estimating, budgeting, managing, and controlling the project costs. Earned value (EV) is a tool that measures the actual work completed and the value of that work, compared to the planned work and the budget. By using EV, the project manager canmonitor the project performance and progress, and identify any variances or deviations from the baseline. The project manager can also use cost triggers and trend analyses to detect and respond to any potential issues or risks that may affect the project cost.

Explanation Fast-tracking is a schedule compression technique that involves performing activities in parallel that were originally planned to be performed sequentially1. This can increase the risk of rework and errors, as well as the stress and workload of the team members2. To motivate the team, the project manager should introduce team-building activities that can enhance the team's trust, collaboration, and morale3. Team-building activities can also help the team cope with the challenges and uncertainties of fast-tracking4.
