We have talked a good deal about the Small Business Rule of Two (not to be confused with the separate VA rule of two for veteran-owned businesses) over the years. The (very) general gist of the rule is this: If the procurement is above the simplified acquisition threshold, the agency must set it aside for small businesses if two or more small businesses can perform the work at fair prices. If the agency has a reasonable expectation that two or more SDVOSB/VOSBs, EDWOSBs/WOSBs, 8(a) participants, or HUBZone participants can perform work under a procurement, the agency must consider setting aside the procurement for that particular category (i.e., if it believes two or more 8(a) participants can perform the work, it can set aside the procurement for 8(a) participants). However, it appears there remains a good deal of confusion about what the Rule of Two requires, as opposed to what it simply permits. In a recent GAO protest, a contractor learned this the hard way, and today, we’ll explore that decision.
