Best Value Tradeoff

Best value tradeoff is a source selection approach where the government evaluates technical factors, past performance, and price together, allowing award to a higher-priced offeror when the additional technical or performance quality justifies the premium.

What is Best Value Tradeoff?

Best value tradeoff, defined under FAR 15.101-1, is the most common source selection method for complex government contracts. It recognizes that the lowest price does not always represent the best deal for the government, a more capable solution at a modest price premium may deliver greater overall value over the life of the contract.

In a best value tradeoff competition:

• Proposals are evaluated against all disclosed evaluation criteria (typically Technical Approach, Management, Past Performance, and Price)
• Technical and past performance factors receive adjectival ratings (Outstanding, Good, Acceptable, Marginal, Unacceptable)
• Price is evaluated but not scored in the same ratings system, instead, it is assessed for reasonableness and realism
• The source selection authority (SSA) makes a documented tradeoff decision comparing the non-price benefits of higher-rated proposals against their price premium over lower-rated competitors

A best value tradeoff decision document must clearly articulate why paying a higher price is worth the additional technical or past performance benefits. This decision is a primary focus of bid protests, protesters often argue that the SSA's tradeoff was unsupported by the record or inconsistent with the disclosed evaluation criteria.

Section M must clearly communicate whether a best value tradeoff approach is being used, which factors are most important, and that price and non-price factors together determine the award.

Why Best Value Tradeoff matters for government contractors

Best value tradeoff is the approach where strong technical solutions and impressive past performance can overcome a price disadvantage. Companies with superior capabilities should focus their pursuit strategy on best value competitions. The key is understanding the specific tradeoff the agency is likely to make: if Technical is far more important than Price, even a 20% price premium can be overcome with exceptional technical scores. If all factors are roughly equal, the tradeoff is tighter. Analyzing prior awards at the agency, comparing award values to competitive pricing, reveals how aggressive the agency's best value calculus tends to be in practice.

Example

Three contractors compete on a best value tradeoff RFP for DoD software development. The SSA's documented tradeoff: Company A, Outstanding Technical, Very Good Past Performance, $12M; Company B, Good Technical, Very Good Past Performance, $10.2M; Company C, Acceptable Technical, Satisfactory Past Performance, $8.8M. The SSA determines that Company A's Outstanding technical rating, including a demonstrated risk reduction methodology that Company B lacks, justifies $1.8M additional cost over Company B for a five-year contract. The SSA documents that the technical risk reduction is worth approximately $500,000 per year in government cost avoidance. Company A wins.

Frequently Asked Questions

What is the difference between best value tradeoff and best value continuum?

The best value continuum is the full range of possible source selection approaches from LPTA (most price-focused) to full tradeoff (most quality-focused). Best value tradeoff is one specific approach on this continuum, specifically the approach where the SSA has discretion to pay a premium for higher technical quality. LPTA is the other commonly named approach at the opposite end of the continuum.

Can the government award to the highest-rated technical offeror regardless of price?

No. The best value tradeoff decision must document that any price premium is justified by specific technical or performance benefits. An SSA cannot simply award to the best technical proposal without addressing why the price difference is reasonable. The tradeoff documentation is critical and is heavily scrutinized in protests.

What happens in a best value competition if there are only minor technical differences between proposals?

When technical proposals are evaluated closely, all Acceptable or all Good, price effectively becomes the deciding factor because there is insufficient technical differentiation to justify paying a premium. The SSA's tradeoff decision in this scenario tends toward the lower-priced technically acceptable offeror.

How do I know what tradeoff the agency is likely to make?

Analyze prior awards at the same agency and contracting office. If their last five awards all went to the lowest-priced technically acceptable offeror even in best value competitions, the practical tradeoff threshold is high. If they regularly award to higher-rated proposals at price premiums of 10-20%, the agency truly exercises best value tradeoff authority. USAspending.gov combined with debriefing data from prior awards reveals this pattern.
