Yeah, when money is going to change hands the paperwork is necessary. It DOES NOT preclude sales presentations or vendor briefings. Period. Show me in that rule/reg where presentations & briefings are forbidden! If that were the case, Uncle Sam would not prevail in the various battlespaces because of the better technology in the hands of our warfighters. Inventors/product developers are brought into the DoD procurement cycle on a regular basis to maintain that technological edge over our adversaries.
