A subcontractor has submitted design documentation on the deliverable due date, but it will require rework. The activity is on the critical path of the project schedule. Which of the following…

Because the activity is on the critical path, any rework duration directly delays the project end date. The PM must first quantify the expected rework duration to understand the full impact, then complete a formal change request to obtain authorization to modify the project schedule and cost baselines - this follows the integrated change control process before any baseline updates occur.

Escalating to the project sponsor to schedule a team meeting bypasses the PM's accountability to first assess the impact and is premature before the scope of the problem is understood.

While assessing rework duration and associated quality activities is partially correct, this answer omits the critical step of initiating a formal change request to authorize modifications to the approved project baseline.

Updating and distributing the master schedule is a step that occurs only after a change request has been formally reviewed and approved through the change control process.
