FAR Part 15 is primarily about which contracting method?

FAR Part 15 is primarily focused on contracting by negotiation. This method allows for more flexibility compared to sealed bidding, as it enables agencies to have discussions with offerors to clarify proposals and negotiate prices. The negotiation process is essential for achieving the best value for the government, especially in complex procurements where discussions about technical requirements, performance, and costs are vital. This part of the FAR outlines the procedures for competitive negotiations, including source selection, evaluation of proposals, and award processes, emphasizing the importance of a systematic approach to obtain the best outcomes in federal contracts.

The other options, while related to different aspects of contracting, do not align with the primary focus of FAR Part 15. Sealed bidding, for instance, is covered under FAR Part 14, which outlines procedures for the competitive and straightforward procurement of goods and services when the award can be made based on price alone. Emergency acquisitions and the acquisition of commercial items are addressed in other parts of the FAR, specifically FAR Part 18 and FAR Part 12, respectively. Therefore, the emphasis on negotiation in FAR Part 15 is what makes it the correct answer to the question posed.
