A vendor supplying a piece of specialized equipment for a project has reported the potential for a delivery delay due to a technical issue with the sub$-$supplier. To stay

on schedule, the vendor proposed replacing the sub$-$supplier's component with a similar part that is different from the one that is stipulated in the project

specifications.

What should the project manager do next?

Insist on using the component per the project specifications and air freight the equipment to mitigate the delay.

Instruct the vendor to use the part that is compliant with the project specifications and update the schedule.

Consult with a subject matter expert $($SME$)$ to see if the proposed change is acceptable.

Accept the proposed replacement in order to keep procurement activities on track.
