Which contract method is utilized when a government agency chooses to negotiate rather than use sealed bidding?

The choice that correctly identifies the contract method used when a government agency opts for negotiation instead of sealed bidding is a negotiated contract under FAR Part 15. This method allows for greater flexibility in discussions between the government and potential contractors. In contrast to sealed bidding, which requires formal bids to be submitted, opened, and evaluated without discussions, negotiated contracts facilitate a dialogue that can help in clarifying needs, refining proposals, and ultimately arriving at an agreement that provides the best value.

Under FAR Part 15, the negotiation process allows for the evaluation of various aspects like technical capability, past performance, and price, providing an opportunity for the government to assess different proposals more holistically. This is particularly useful in complex procurement situations where sealed bidding may not sufficiently address the unique requirements or complexities of the contract.

The other methods mentioned do not involve negotiation; for example, FAR Part 13 pertains to simplified acquisition procedures that are generally used for smaller contracts and also do not involve sealed bidding. FAR Part 14 specifically covers the sealed bidding process, and commercial item contracting focuses on contracts for commercial products and services but does not inherently describe the negotiation process as outlined in FAR Part 15. Thus, FAR Part 15 is the appropriate choice in this context.
