A customer requests the project be finished 10 days earlier for marketing reasons. After discussing with the team, the project manager concludes this is possible if some activities are overlapped. What should the project manager do?

The project manager should fast-track activities while considering constraints and dependencies. Fast-tracking is a schedule compression technique where activities that would normally be done in sequence are performed in parallel, or overlapped, to shorten the project duration. This directly addresses the customer's request to finish earlier. The project manager must carefully consider constraints and dependencies to avoid negative impacts like increased risk or rework. Delivering a minimum viable product earlier is a valid agile approach but isn't explicitly stated as an option for this scenario. Resource leveling optimizes resource allocation but doesn't inherently shorten the schedule. Adding subject matter experts might help, but fast-tracking is the direct technique for overlapping activities to compress the schedule.
