Section 15.002 - Types of negotiated acquisition(a)Sole source acquisitions. When contracting in a sole source environment, the request for proposals (RFP) should be tailored to remove unnecessary information and requirements; e.g., evaluation criteria and voluminous proposal preparation instructions.(b)Competitive acquisitions. When contracting in a competitive environment, the procedures of this part are intended to minimize the complexity of the solicitation, the evaluation, and the source selection decision, while maintaining a process designed to foster an impartial and comprehensive evaluation of offerors' proposals, leading to selection of the proposal representing the best value to the Government (see 2.101).
