According to GSA guidance on procurement integrity and document retention, the challenger should preserve every award email, debriefing note, solicitation amendment, and agency memo within the first 24 hours. That record becomes the backbone of the case. Per FAR and SBA policy, the protester should compare the awarded scope against the Phase II statement of work, the deliverables, and any transition plan. If the follow-on is substantially larger, shifts to a new mission area, or includes foreign-disclosure or cyber requirements not present in the earlier phase, the company should flag those differences immediately. The court cares less about labels and more about whether the agency’s decision was rational, documented, and consistent with the statute. That is why many SBIR cases turn on the first written record, not on later testimony. The company that organizes the file quickly usually has the better chance of showing prejudice and obtaining meaningful relief.
