A vendor has manufactured a complex product.

The project manager should assess the schedule impact of the deficiencies identified during the factory acceptance test and evaluate the most feasible solution to keep the project on track. This may involve negotiating with the vendor, performing a schedule compression technique, or implementing a contingency plan. The project manager should also communicate the issue and the solution to the relevant stakeholders and update the project documents accordingly. The other options are not advisable, as they may compromise the quality of the product, increase the project risk, or create conflicts with the vendor. References: PMBOK Guide, 7th edition, page 112-113, 118-119, 122-123.
