Why debriefings matter
A debriefing is a structured exchange between the agency and an offeror after the source selection decision. The agency explains why the offeror was not selected (or, in pre-award cases, why a proposal was eliminated from competition). For the offeror, the debriefing serves three purposes: understanding what to improve on the next pursuit, gathering information that informs a possible bid protest, and meeting the timing condition that extends the protest filing window.
Skipping a debriefing — when you are entitled to one — typically forfeits the most useful learning opportunity in the entire procurement cycle and may shorten your protest window.
Required versus enhanced debriefings
Required (FAR 15.506)
In a negotiated procurement under FAR Part 15, an unsuccessful offeror is entitled to a debriefing on request. The request must be submitted within 3 days after the offeror receives notice of contract award. The agency must conduct the debriefing as soon as practicable.
Required debriefings cover: significant weaknesses or deficiencies in your proposal, the overall evaluated cost or price and technical rating of your proposal and the awardee, past performance information used in the evaluation, the rationale for award, and reasonable responses to relevant questions about source selection procedures.
Enhanced (DoD, DFARS 215.506-70)
DoD provides "enhanced" debriefings on contracts above $10 million (lower thresholds for certain small businesses). Enhanced debriefings allow the offeror to submit follow-up written questions within 2 business days of receiving the debriefing, with agency answers due within 5 business days.
The enhanced framework extends the protest filing window — the protest clock effectively runs from receipt of the agency's responses to follow-up questions rather than from the original debriefing date.
Pre-award (FAR 15.505)
When the agency eliminates an offeror from the competitive range before award, the offeror may request a pre-award debriefing. These debriefings address why the proposal was eliminated, not the eventual award decision.
Pre-award debriefings are narrower in scope than post-award debriefings but valuable for understanding evaluator concerns early, when the offeror may still influence its position on related opportunities.
What the agency must and must not disclose
The debriefing rules carefully balance disclosure to the unsuccessful offeror against protection of the awardee's proprietary information. The agency must disclose:
- Significant weaknesses or deficiencies in your proposal
- Your overall evaluated rating and the awardee's overall evaluated rating
- The overall evaluated cost or price for both your proposal and the awardee's
- Past performance information used in your evaluation (yours, not the awardee's, unless redacted appropriately)
- The rationale for the award decision
- Reasonable responses to relevant procedural questions
The agency must not disclose:
- Point-by-point comparison of your proposal with other offerors' proposals
- Trade secrets or privileged commercial and financial information of other offerors
- Specific technical proposal content of competitors
- Names of individual evaluators
- Source selection plan content beyond what is published in the solicitation
Where the line falls is often disputed. Agencies vary in how generous they are with detail. Most allow more disclosure when the unsuccessful offeror asks specific, focused questions rather than blanket "tell me more" prompts.
The protest clock
The timing relationship between debriefing and protest is the single most important procedural piece. The relevant rules:
- Standard window. A GAO protest must be filed within 10 days after the basis for protest is known or should have been known.
- Debriefing extension. If a debriefing is required and was timely requested, the 10-day clock runs from the debriefing date — extending the window by however long it took the agency to schedule the debriefing.
- 5-day automatic stay window. Under CICA, if the protest is filed within 5 days of a required debriefing, the agency must suspend award or performance pending GAO's decision. This is the most consequential timing feature.
- Enhanced debriefing (DoD). Submitting follow-up questions extends the protest filing window further, and the 5-day automatic stay window runs from receipt of the agency's responses.
For more on the protest process itself, see GAO bid protests.
How to prepare for a debriefing
- Submit the request within 3 days. Calendar this deadline the moment you learn of the award.
- Review your proposal. Re-read your submission with the evaluator's hat on. What weaknesses are likely to surface?
- Compile specific questions. Generic "Why didn't we win?" gets generic answers. Specific questions ("Why was our technical approach scored Acceptable rather than Good?") get specific answers.
- Decide who attends. The capture lead, proposal manager, and technical lead are typical. Including counsel is appropriate for high-value pursuits or where protest is a realistic option.
- Plan to take notes, not just listen. Detailed notes are essential for the protest decision and for capture process improvement. The agency provides a written summary in some cases but not always.
- Have follow-up questions ready (DoD enhanced). Plan the post-debriefing question set in advance; you have only 2 business days to submit.
Common questions worth asking
- What specific weaknesses or deficiencies were identified in our technical approach?
- How did our past performance rating compare to the awardee's?
- What was the awardee's overall evaluated price, and how did the price-technical tradeoff play out?
- Were any of our proposed approaches considered unacceptable, and if so, why?
- How were specific evaluation criteria applied — for example, the relative weight of cost realism within the price factor?
- Were there any clarifications or exchanges we were not invited into that affected the source selection?
- Did any of our proposed key personnel fail to meet the minimum qualifications?
Avoid asking the agency to compare your proposal directly to the awardee's technical content — the agency cannot answer.
Common mistakes
- Skipping the debriefing. You lose the learning opportunity and shorten your protest window.
- Treating the debriefing as a chance to argue. The agency is explaining a completed decision, not negotiating. Arguing in the debriefing accomplishes little and can produce a less-detailed written record.
- Asking only general questions. Specific questions produce specific answers. Plan them in advance.
- Missing the follow-up question window. For DoD enhanced debriefings, the 2-business-day window is short. Have questions drafted before the debriefing starts.
- Conflating the debriefing with the source selection record. The full record includes more than the debriefing covers. If a protest follows, the agency report will surface additional material.
- Forgetting that the clock is running. Every hour after a required debriefing eats into the 5-day automatic stay window. Decide on protest within days, not weeks.
