Which of the following actions can result from a contractor purchasing system review?

A contractor purchasing system review is an essential process to ensure that a contractor's procurement practices align with federal regulations and standards. Various outcomes can result from such a review, depending on the findings.

The withdrawal of approval for the contractor's purchasing system occurs when the review identifies significant deficiencies or non-compliance with regulatory requirements. This action is a serious consequence as it can affect the contractor's ability to procure goods and services under federal contracts.

Granting approval for the contractor's purchasing system happens when the review shows that the system meets all applicable standards and operates effectively. This approval is crucial for the contractor to engage in federal procurement activities efficiently, as it instills confidence in their purchasing controls.

Withholding approval of the contractor's purchasing system is another potential outcome. This could occur if the review reveals some issues that require corrective actions before full approval can be granted. This provisional status allows the contractor time to address concerns while still not being completely barred from federal contracting opportunities.

Since all these actions can directly result from a contractor purchasing system review based on its findings, the comprehensive nature of the outcomes supports the inclusion of all possibilities as valid results from the review process. Therefore, the most accurate response reflects the full range of potential outcomes associated with such reviews.
