According to GSA and GAO, the most frequent protest triggers are (1) inconsistent or undocumented evaluation decisions, (2) failure to follow solicitation requirements, and (3) defective past performance submissions. Per FAR, procedural errors—late proposals, missing representations, and improper debriefings—also prompt protests; GAO sustains protests when agencies cannot justify evaluations or correct process errors within required timelines.
