After the merger of two large companies, a project manager is assigned to a project. The company hires a consultant to ensure best practices are being used in information security. During an iteration, the consultant requests changes to a software component, claiming that it is not meeting market requirements. What should the project manager do?

This option overlooks the necessity of validating the consultant's requests with the customer. Simply adding changes without customer feedback may lead to misalignment with actual market needs and could result in wasted resources if the changes are ultimately not acceptable.

Canceling the iteration disrupts the workflow and may cause delays in project timelines. Moreover, making changes without consulting the customer does not guarantee that the adjustments will meet their expectations or requirements, which could lead to further issues down the line.

While meeting with the product owner is important, canceling the iteration is not the best course of action. Engaging with the product owner without first reviewing the consultant's changes with the customer may lead to decisions made in isolation, which can further disconnect the project from actual market needs.
