(b) Except for “sources sought” synopses, market research is the responsibility of program managers or the requiring activity. However, all members of the acquisition team must be cognizant of available emerging technology. Requirement statements must reflect any available commercial solutions. Requirements personnel and contracting officers must work together as a team to gather market data needed to make decisions. Market research utilized to justify sole source must be complete and not more than 12 months old. A statement that the solicitation will be synopsized and that all proposals received will be evaluated is not a substitute for performing adequate market research and in itself does not support and justify sole source.
