During initiation, the project manager discovers that Project A has finish-to-start dependencies with Project B. However, Project B has not even been started and Project A has resources booked against it already. What should the project manager do?

Executing Project B with resources allocated to Project A contradicts the established dependency, as Project A cannot start until Project B is completed. This action could lead to resource conflicts and mismanagement, further complicating both projects' timelines.

Cancelling Project A indefinitely is an extreme measure that does not consider the possibility of reassessing timelines or resource allocation. It could lead to lost opportunities and waste, especially if Project A is still viable but requires adjustments to its schedule.

Keeping Project A active without addressing the dependency issue may lead to wasted resources and effort on a project that cannot progress. This approach may also confuse team members about priorities and timelines, leading to inefficiencies in project management.
