Contractors are supposed to submit their initial best offer because award might be done without discussion. But we all know that once the contractors are ranked and graded and the competitive range is established, most of the time, the Contracting officer will issue a request for Best and Final Offer. Proposal development is costly. Multiple submissions also cost money. Contracting Officers are "required" to always ask for a lower price. Adjust the regulations to make an award based on the initial proposals submitted. Obtain clarifications as necessary, but then make an award.
