Government Contract Debriefings: How to Get Feedback After a Loss and Use It to Win Next Time

You lose a bid. You get the standard notification — "We regret to inform you that your offer was not selected." You move on to the next opportunity. That’s what most small businesses do, and it’s one of the most expensive habits in government contracting.

The right to a debriefing — a formal session where the contracting agency explains why your proposal lost — is written into the Federal Acquisition Regulation. It’s not optional for the agency when you request it. They have to do it. Most small businesses either don’t know this right exists or don’t think it’s worth pursuing. Both assumptions are wrong.

A proper debriefing tells you exactly where your proposal scored, what weaknesses the evaluators identified, how your price compared to the winner’s, and in many cases what you could have done differently. That information is worth thousands of dollars in avoided proposal mistakes on the next bid.

The contractors who consistently improve their win rates treat debriefings as mandatory post-loss intelligence. Not optional. Not when convenient. Every time, for every substantive loss.

The FAR gives you two distinct debriefing rights, governed by two different regulations. Which one applies depends on where you are in the procurement process when you find out you’re not getting the contract.

Preaward debriefings (FAR 15.505)apply when the agency eliminates your offer from the competitive range — meaning they’re cutting you before they make the final award. You have the right to a preaward debriefing that must cover why your proposal was excluded, the evaluation of your significant weaknesses or deficiencies, and a summary of the rationale for exclusion. The agency does not have to reveal information about other offerors’ proposals at this stage.

Postaward debriefings (FAR 15.506)are the more common and more information-rich version. After award, unsuccessful offerors can request a debriefing that covers the evaluation of their proposal across all factors, the overall ranking if the agency used rankings, the awardee’s evaluated price or cost, and the basis for the source selection decision. This is where the real intelligence lives.

Most of this guide focuses on postaward debriefings because that’s where you get the most complete picture of where you stood. But if you’re cut from competitive range early, don’t skip the preaward debriefing — knowing why you were excluded tells you whether the problem was technical, past performance, or something else entirely, and that’s valuable regardless of what stage it happened at.

The deadline is tighter than most people realize. Under FAR 15.506(a)(1), you must submit a written request for a postaward debriefing within 3 business days of receiving written notification that your offer was not selected. Miss that window and the agency is not required to provide the debriefing — though many will still accommodate a late request at their discretion.

The request must be in writing. An email to the contracting officer is sufficient. Keep it short and direct. You don’t need to explain why you want the debriefing or what you think went wrong. Just submit the request promptly.

Once you’ve submitted the request, the agency must hold the debriefing within 5 business daysof receiving your request (FAR 15.506(b)). They can request a later date if there’s a legitimate scheduling reason, but the default is fast.

Debriefings can be oral, written, or a combination. Many agencies conduct oral debriefings by phone or videoconference, then follow up with a written summary. For complex procurements, push for a written follow-up even if the initial debriefing is oral — written summaries are harder to misinterpret and more useful when feeding the information back into your proposal process.

If the agency doesn’t respond to your request within a reasonable timeframe (a few business days), follow up in writing, copying the contracting officer’s supervisor if needed. Your request creates a record. Agencies are generally responsive because the debriefing obligation is clearly stated in the FAR and in most contracts.

The FAR is specific about what a postaward debriefing must cover. FAR 15.506(d) lists required disclosures. Contracting officers can expand beyond this list at their discretion — and the good ones usually do — but the minimum is clearly defined.

The agency must tell you:

• The government's evaluation of the significant weaknesses or deficiencies in your proposal

  Not just that you were weak on a factor — the specific nature of the weakness
• The overall evaluated cost or price, and technical rating if applicable, of the awardee

  You find out exactly what the winning company bid and how they scored technically
• The overall ranking of all offerors, if the agency used rankings

  Whether you came in second, fifth, or last — context that matters
• A summary of the rationale for award

  Why this particular contractor won, beyond just price
• Reasonable responses to relevant questions about whether source selection procedures contained in the solicitation, applicable regulations, and other applicable authorities were followed

  You can ask process questions — and they have to answer

The agency does not have to disclose:

• Trade secrets and confidential manufacturing processes of other offerors
• Privileged or confidential commercial and financial information of other offerors
• Point-by-point comparisons of your proposal with those of other offerors
• The names of individuals on the Source Selection Evaluation Board
• Information exempt from release under the Freedom of Information Act

Many contracting officers will share more than the minimum if they believe it helps improve the contractor community — particularly on longer-term requirements where they want multiple capable bidders. The spirit of the debriefing is to provide meaningful feedback, not just to check a compliance box. If your debriefing feels perfunctory, ask follow-up questions (more on this in the enhanced debriefing section).

If you’re bidding on Department of Defense contracts, the National Defense Authorization Act for FY2018 (Section 818) gave you significantly stronger debriefing rights — and many contractors who work DoD don’t know these rights exist.

DFARS 215.506-70 implements the enhanced debriefing process. It applies to DoD competitive acquisitions — including task orders and delivery orders — that exceed $10 million(DFARS inflation adjustments may move this threshold to $15 million; verify against current eCFR before relying on it for a specific procurement). Here’s how it works: after an oral debriefing on a qualifying DoD contract, you have 2 business days to submit written follow-up questions to the contracting officer. The agency then has 5 business days to provide written responses. Those written responses are part of the official debriefing record.

The debriefing is legally not concluded — and protest clocks do not begin running — until the later of: two business days after the initial debriefing if you submit no follow-up questions, or the date the agency delivers its written responses to your timely submitted questions. This means enhanced debriefings give you substantially more time to evaluate what happened and decide whether a protest is warranted.

There’s an additional right many contractors miss entirely: for DoD contracts above $150 million, the agency is requiredto provide a redacted copy of the written Source Selection Decision Document (SSDD) during the debriefing. For contracts between $15 million and $150 million where the unsuccessful offeror is a small business or nontraditional defense contractor, disclosure of the SSDD is optional — but you can ask for it, and some contracting officers will provide it. The SSDD is the evaluator’s own internal document explaining exactly how the award decision was made.

Use your follow-up questions strategically. If the oral debriefing was vague about a specific evaluation factor — say, your management approach rating — ask explicitly in writing: “What specific weaknesses or deficiencies did the SSEB identify in our Management Volume?” Written questions get written answers, and written answers are documented and defensible if you later decide to protest.

The connection between debriefings and protests is direct, and it affects your decision-making even if you never plan to file a protest.

Under GAO protest procedures, you generally have 10 days from when you knew or should have known the basis for protest to file at the Government Accountability Office. If you request a timely debriefing and attend it, your 10-day protest window starts from the date of the debriefing — not from the date of the award notification. That gives you more time to evaluate whether you have a protest-worthy case.

For the CICA automatic stay — which halts contract performance while GAO considers the protest — the deadline is tighter: you must file at GAO within 10 days of award or within 5 days from the close of a required debriefing. Miss those windows and GAO can still hear your protest, but there’s no automatic stop-work order while it’s pending.

If you don’t request a debriefing, the protest clock runs from the date of award notification — and 10 days goes fast when you’re running a business.

That 52% effectiveness rate is the critical number. More than half of contested GAO protests result in the protester winning or the agency correcting the procurement voluntarily — because the protest itself shined a light on an evaluation problem. Debriefings are what tell you whether an evaluation problem worth contesting actually exists.

This matters even if you’re not a frequent protest filer. Sometimes debriefings reveal procedural irregularities — an evaluation that didn’t follow the RFP criteria, a technical rating that doesn’t match the stated evaluation factors, a price that suggests the awardee may have made an error — that you simply couldn’t have known without the debriefing.

For more on the protest process itself — when it makes sense, what it costs, and how to evaluate whether you have a viable case — see our guide to government contract protests.

Contractors who walk into debriefings unprepared get less out of them. The contracting officer has a set agenda and limited time. If you don’t come with specific questions, you’ll get general answers — which aren’t useful.

Before the debriefing, review your proposal thoroughly. Identify the sections where you felt least confident. Pull out the evaluation criteria from Section M and note every factor where you were uncertain about your response. Those are the areas to probe.

Bring two or three people from your team. One person leads the conversation. One person takes verbatim notes — not summaries, actual quotes from the contracting officer wherever possible. One person listens for things the lead might miss and asks follow-up questions. This division of labor pays off when you’re reviewing the notes afterward.

Keep the debriefing professional and forward-looking. Contracting officers are more candid when they feel the conversation is about improvement, not blame. Don’t argue with their evaluation — you won’t change the award, and it closes them off. If you believe the evaluation was flawed, write it down and evaluate it after the session, not during.

The best debriefing conversations are ones where the CO ends up saying more than they planned to, because the contractor asked good questions and listened carefully.

Vague questions get vague answers. “Why did we lose?” gets you “Your technical approach had some weaknesses.” That’s useless. Specific questions get specific answers.

Here are the question categories and specific phrasings that consistently produce more useful debriefings:

Document everything the CO says in the most direct language possible. If they say “your management approach lacked specificity on transition,” write that verbatim. If they say “the awardee’s price was substantially lower than yours,” note the word “substantially.” These specifics matter when you’re doing your post-loss analysis.

The debriefing isn’t the endpoint. It’s the input. What you do with the feedback determines whether it was worth requesting in the first place.

Context on the market: in FY2024, the federal government awarded $773.68 billion in contracts across 108,899 companies. Small businesses captured $183 billion of that — about 28.8% of prime contract spending, a record. There is no shortage of opportunity. The question is how many of those opportunities convert to wins for your company specifically.

Industry data consistently shows companies that run formal bid/no-bid processes win around 28% of the time. Companies that bid without a disciplined selection process win around 12%. That gap — 28% vs. 12% — closes fastest when you have a consistent source of feedback on what your proposals are missing. Debriefings are that source.

Start with a structured debrief document — a simple one-page summary that captures: what factor drove the loss, the specific weaknesses identified, how your price compared, and the key action items for next time. File it alongside your proposal and the solicitation documents. You want to be able to pull this up when the recompete drops in two years.

Most losses cluster around a small number of root causes. Track yours across multiple debriefings and you’ll see patterns fast. Common patterns:

One debriefing gives you a data point. Three or four debriefings give you a pattern. Ten debriefings tell you exactly where your proposal process is systematically weak — and that’s the information that changes your win rate.

Feed debriefing findings directly into your capture management process. When a new opportunity comes in, the first question isn’t just “can we win this?” but “are the same weaknesses that hurt us last time still present?” If yes, either fix them before bidding or make the no-bid call honestly.

The most competitive small business contractors treat every proposal as part of a learning system, not a one-off event. Debriefings are the feedback mechanism that makes that system work.

Set this standard in your company: every proposal loss gets a debriefing request, and every debriefing result gets logged in a shared document. That document is the basis of your quarterly proposal review — a session where your leadership team looks at what you won, what you lost, and what the debriefing feedback said about why.

The contractors who consistently improve their probability of win over time aren’t necessarily smarter or better resourced. They’re more disciplined about learning from losses. A company that bids 20 contracts and requests debriefings on every loss will outlearn a company that bids the same 20 contracts and skips the debrief.

There’s also a relationship dimension. Contracting officers notice contractors who take debriefings seriously. Showing up prepared, asking good questions, and clearly using the feedback to improve signals that you’re a serious player in their space. That reputation matters when you’re in a competitive range on the next solicitation. For more on building those relationships, see our guide to working with contracting officers.

Your proposal pipeline is only as good as the feedback that feeds back into it. Debriefings are the cheapest, fastest, most authoritative source of that feedback — and you have a legal right to them. Use it every time.
