Agencies often take corrective action when there is a defect in the procurement process, and it can be in response to a bid protest or an internal review. The FAR Part 33.104(c)(1) requires a contracting officer to suspend performance of an awarded contract if they receive notice of a protest from the GAO within 10 days after contract award or within 5 days after a debriefing date offered for a required debriefing, whichever is later. This automatic stay often leads to corrective action.
Common reasons for corrective action include issues with the evaluation of proposals, such as applying criteria inconsistently or failing to follow the stated evaluation methodology in Section M. It can also happen when there is a concern about the awardee's eligibility, like if a small business set-aside was awarded to a firm that did not meet the size standard. Sometimes, an agency will discover an error on its own, like a miscalculation in the price evaluation, and will take corrective action to fix it before a protest is filed. You should reach out to the contracting officer for more information about the specific reason for the corrective action on your SDVOSB set-aside.
