Sealed bidding and competitive proposals.
FAR 6.401 explains the two basic competitive source-selection methods that may be used under the competition requirements in FAR Part 6: sealed bidding and competitive proposals. It points the reader to the detailed procedures in FAR Part 14 for sealed bidding and FAR Part 15 for competitive proposals, and it clarifies when each method is appropriate. The section is important because it helps contracting officers choose the right acquisition method based on the nature of the requirement, the need for discussions, the basis for award, and the likelihood of receiving multiple bids. It also addresses a special practical issue for contracts performed outside the United States and its outlying areas, where discussions are generally necessary because of differences in law, regulations, and business practices. In practice, this section is a decision rule: if the conditions for sealed bidding are met, the contracting officer must use it; if not, competitive proposals may be used, and for overseas work competitive proposals will usually be the default unless sealed bidding is clearly appropriate and discussions are unnecessary.
