Project A and Project B share a team member. The team member is falling behind on a task for Project B. Which of the following is the BEST action to take to get the task for Project B back on track?

Negotiating for more of the team member's available time addresses the fundamental issue of resource contention and allocation, especially when a resource is shared across multiple projects. This involves discussion with the other project manager or functional manager to adjust priorities or allocate additional time to Project B, which is often the most effective long-term solution.

Assigning overtime is a short-term fix that can lead to burnout, decreased quality, and increased costs, and doesn't solve the underlying resource conflict.

Assisting the team member might provide temporary relief but doesn't resolve the resource constraint and may not be scalable or sustainable for the project manager.

The project manager completing the task is generally not an appropriate or sustainable solution, as it diverts the PM from their core responsibilities and doesn't empower the team member.
