Best-Value Tradeoff

What is Best-Value Tradeoff?

Best value is the umbrella concept for source selection in negotiated US procurements under FAR Subpart 15.1, spanning a continuum from lowest-price technically-acceptable (LPTA) at one end to full tradeoff at the other. In the tradeoff process (FAR 15.101-1), the government may select a higher-priced, higher-rated proposal when the added non-price benefit — technical merit, past performance, management approach — is worth the price premium. The relative importance of price versus non-price factors must be stated in the solicitation.

This contrasts with LPTA (FAR 15.101-2), where the award goes to the lowest-priced offer that meets defined acceptability standards, with no credit for exceeding them. Policy has narrowed appropriate LPTA use, steering agencies toward tradeoff for requirements where quality differences matter. The source-selection decision must be documented to show the rationale for any tradeoff, including why a price premium is justified.

For vendors, the evaluation method dictates bid strategy. Under tradeoff, investment in technical narrative, demonstrable outcomes, and a strong past-performance record can win at a higher price. Under LPTA, exceeding the minimum brings no reward, so the strategy is to meet every acceptability standard at the lowest sustainable price. Reading the solicitation's evaluation section to identify which method applies is a first-order qualification step.
