What should the project manager do to address this recurring issue?

Work with the vendor to improve their understanding of integration requirements and establish better acceptance criteria

Accept the additional integration work as part of the project scope since the components meet specifications

Replace the vendor with one that has better integration experience

Assign internal resources to handle all integration work for this vendor's components
