DFARS Part 215 — Negotiation (DoD overlay on FAR Part 15)

What this Part does

DFARS Part 215 overlays FAR Part 15 for DoD source selections, adding three material layers that didn’t exist in civilian procurement:

  1. Should-cost analysis (215.407-4) — a DoD-specific cost- realism technique that starts not from “what did the contractor propose?” but from “what should this cost if the contractor were optimally run?” A hostile tool from the contractor’s perspective, a powerful one from the government’s.
  2. Enhanced debriefings (215.506) — DoD contracts over 100M) provide a more expansive post-award debriefing than FAR’s baseline, with a 2-day window for follow-up questions. Preserving enhanced debriefing rights can extend the CICA stay clock by critical days.
  3. Stricter cost/price proposal adequacy requirements (215.408, 215.404-2) — Table 15-2 equivalent for defense, with more specific disclosure formats and documentation. The peer review requirement for major system source selections (215.300) is in this Part too.

Part 215 also implements DoD-specific TINA (Truthful Cost or Pricing Data) rules under DFARS 252.215-7002 et seq., which track FAR FAR 15.403 but with tighter DoD interpretation of commercial-item exceptions.

When you’d look here

  • Your client is in a DoD source selection over $10M and wants to preserve enhanced debriefing rights (read 215.506 before the debriefing request).
  • A should-cost review has been announced for a major program — very different posture than ordinary cost-realism.
  • The CO is demanding certified cost or pricing data on what your client argues is a commercial item — 215.404 and the interplay with DFARS Part 212 commercial-item determinations.
  • The government is asserting a defective pricing claim under DFARS 252.215-7002 — post-award cost/price audit finding that disclosed data was not current, accurate, or complete.
  • A peer review requirement is triggered (over 500M for contract awards) and the program schedule is tight.

Case study: enhanced debriefing and the CICA clock extension

Sentinel Systems (hypothetical) was unsuccessful on a $240M Air Force cyber-operations support contract. The award was announced on a Tuesday. Sentinel requested a debriefing per FAR 15.506 and DFARS 215.506 on Wednesday — within the 3-day post-award window under 15.506-(a).

Because the contract was over $100M, enhanced debriefing rights under DFARS 215.506-70(d) kicked in automatically. The enhanced debriefing (a) lasts a minimum of 5 business days before closing, and (b) allows offerors to submit follow-up questions within 2 business days of the initial debriefing.

Sentinel’s counsel scheduled the debriefing for Friday. The agency provided the initial debriefing orally (typical DoD practice). Sentinel submitted written follow-up questions on the following Tuesday. The agency answered on Thursday. The debriefing closed on Thursday — and only at that point did the 5-day GAO protest clock under FAR 33.104 and the CICA automatic-stay window begin.

By preserving enhanced debriefing rights, Sentinel effectively extended its protest window from roughly 8 calendar days (Tuesday award + 3-day debriefing + 5-day protest window) to 14 calendar days (Tuesday award + Friday initial debriefing + Tuesday follow-up + Thursday closure + 5-day protest window).

Those extra days let Sentinel identify a specific unequal-treatment issue in the technical evaluation that hadn’t been apparent in the initial debriefing. Sentinel filed a GAO protest that was eventually sustained in part, resulting in corrective action and a re-award process.

Teaching points:

  1. Enhanced debriefing is available to DoD contracts over 100M. The offeror preserves it by requesting the debriefing promptly AND by submitting follow-up questions within the 2-day window.
  2. The debriefing “closes” when the agency answers the last follow-up question, not when the initial debriefing ends. Use this to maximize the protest window.
  3. Even without enhanced debriefing, pay attention to the CICA stay. Post-award protests filed within 5 days of debriefing closing (or 10 days of award, whichever is later) trigger the automatic stay of performance under 31 USC 3553(d).

Case study: the should-cost trap

Aurora Defense (hypothetical), a major-system prime, was in negotiation on a production follow-on contract for an unmanned aerial vehicle. Initial contract was $1.4B over 3 years. The Air Force program office announced a should-cost review per DFARS 215.407-4 before entering formal negotiations.

Should-cost is not a TINA disclosure; it’s the government’s independent judgment about what the program should cost absent contractor inefficiency. The review identified ~$180M of projected savings by:

  • Redesigning the materiel management process (government believed contractor could reduce inventory float).
  • Re-sourcing a specialty component to an alternate supplier with a lower unit price.
  • Eliminating a DFAR (Design For Assembly Review) step the government determined was redundant.

Aurora’s push-back: (a) the materiel management “inefficiency” was driven by late government-furnished equipment deliveries in the prior contract, (b) the alternate supplier was not qualified for the specific component, (c) the DFAR step was required by the contractor’s internal quality system and eliminating it would void the contractor’s workmanship warranty.

Negotiations lasted 8 months. The settlement: Aurora accepted a 40M of prior GFE-delay responsibility and accepting Aurora’s quality-system argument. Aurora also agreed to a fixed-price incentive structure on the contract with shared savings on any should-cost improvements realized during performance.

Teaching points:

  1. Should-cost is not a TINA proceeding. It’s a unilateral government technique; contractor has no disclosure obligation (should-cost doesn’t create one). But practically, a contractor has to respond with equivalent rigor or lose ground.
  2. Push back hard on should-cost premises. The technique has a bias toward attributing prior-contract cost overruns to contractor inefficiency. A disciplined retrospective can allocate cost drivers differently.
  3. Should-cost often converts to incentive structures in negotiation. A fixed-price incentive or cost-share provides a vehicle for realized savings to be shared rather than locked in at the should-cost point estimate.
