Are Small Business Concerns "Nontraditional Defense Contractors?" in Don Mansfield's Blog A blog by Don Mansfield Posted April 3 · Report reply Seems to me the question is whether a CO would or could use Part 12 procedures, without using any Part 15 procedures, if market research determined that at least one potential offeror was a non-traditional defense contractor ("NTDC"). If the CO thought some offerors were NTDCs but some were not, could the CO use Part 15 procedures for the others but use Part 12 procedures for the NTDCs? For some reason, I think that would be problematic. So I think that leaves our CO with the same option -- use Part 12 or Part 15 procedures, but pick one and stick with it. If the CO uses Part 15, then the NTDC would seem to be stuck with that choice. But perhaps I'm over analyzing this. What do others think?
