All activities for Project A are ahead of schedule, except for one activity that is on the critical path. The resource manager is requesting that the team members join Project B, which is an important

Asking stakeholders to pause Project A when it is largely on track and has existing commitments would be a drastic measure, going against the project manager's responsibility to deliver their project as planned, without a clear, higher organizational mandate.

While seemingly a compromise, releasing team members from Project A, even those not directly on the critical path, could still reduce the project's overall capacity and its ability to maintain its 'ahead of schedule' status or efficiently manage the single critical path activity, thereby putting commitments at risk.

Agreeing to reassign all team members would completely derail Project A and its commitments, which is contrary to the project manager's core responsibility, especially when Project A is performing well and has its own critical activities.

The project manager's primary responsibility is to deliver Project A as committed, especially since it is largely ahead of schedule, despite one critical path activity that still requires focused attention. Removing team members to support another project (B), even if B is important and behind, risks jeopardizing Project A's successful completion and established commitments. Unless there is a formal organizational directive to reprioritize, the PM should protect the resources allocated to their project to ensure its planned delivery.
