Thank you, Vern. I completely agree with your school of thought. Contracting should serve as the lead in any and all conversations/communications prior to award.
The program that I have taken over consists of numerous moving parts and the previous CO/CS was not as involved in fact-finding questions that the program office sent to the contractor. Since taking over, I have noticed that the program office was actually negotiating with the contractor and revised proposals would be submitted.
I explained the issues with the program office that they do not have the authority to negotiate on behalf of the government and when they ask the contractor to "adjust/reduce" costs, that is considered negotiating. Additionally, I requested that they send me all of the fact-finding questions they have for me to review prior to dissemination to the contractor.
They asked for a handout to help them understand the differences when drafting any fact-finding questions for the future, which is why I asked the original question.
I would like to thank everyone for their feedback and this helpful discussion.
