The Scale of What Moves Through This System
The Department of Defense obligated approximately $445 billion in contracts in FY2024, roughly 60% of all federal contracting dollars. That spending flowed to thousands of companies through an acquisition process governed by the Federal Acquisition Regulation (FAR), its defense supplement (DFARS), and a web of agency-specific policies that collectively determine which companies get to build what the military uses.
Small businesses received $183 billion in prime federal contracts in FY2024, representing 28.8% of all federal contracting dollars, and DoD earned an “A” rating on the FY2024 Small Business Procurement Scorecard. On the surface, the system appears accessible.
But the process through which those dollars get allocated, from the first market signal to a signed contract, is opaque, slow, and structurally biased toward companies that already understand it. For companies entering the defense market for the first time, the acquisition cycle is the single largest barrier to entry, larger than technology risk, larger than capital requirements, and larger than security clearance timelines.
Understanding the mechanics is not optional. It is a prerequisite.
Phase 1: Market Intelligence (RFI and Sources Sought)
The acquisition cycle begins long before a formal solicitation appears. Program offices start by gathering market intelligence through two primary instruments.
A Request for Information (RFI) is a non-binding notice posted to SAM.gov or agency forecast portals. It signals that a program office is exploring a requirement and wants to know what the market can provide. RFIs do not commit the government to a procurement. They are research tools. But they are also the earliest public signal that a contract opportunity is forming.
A Sources Sought Notice serves a similar purpose with a narrower focus: the program office is specifically trying to determine whether qualified small businesses can perform the work. The answer to this question determines whether the eventual solicitation will be set aside for small businesses or opened to full and open competition.
The mistake most new entrants make at this stage is treating RFIs and Sources Sought notices as passive reading material. They are not. They are the beginning of a conversation. Program offices use the responses to shape requirements, refine evaluation criteria, and identify potential competitors. A well-crafted RFI response that demonstrates relevant capability and asks informed questions can influence how the requirement is written, often in ways that favor the respondent’s strengths.
The time between an RFI and a formal solicitation varies widely. For routine requirements, the gap may be 3 to 6 months. For complex weapons programs or IT modernization efforts, it can stretch to 12 months or longer. The requirements package and statement of work alone can take 6 to 12 months to develop.
This lead time is not wasted time. It is positioning time. Companies that engage at the RFI stage and build relationships with the program office during the pre-solicitation period have a structural advantage over companies that discover the opportunity when the RFP drops.
Phase 2: Pre-Solicitation and Draft RFP
Before releasing a final solicitation, many program offices issue a draft Request for Proposal (RFP) or a pre-solicitation notice for industry comment. This step allows the government to test its requirements, evaluation criteria, and contract structure against market feedback before committing to a formal competitive process.
Draft RFPs are underutilized by small contractors. Comments submitted during the draft phase can result in changes to scope, evaluation weights, small business set-aside determinations, and technical requirements. The government is required to consider industry feedback and, in practice, frequently revises solicitations based on substantive comments.
Industry days, pre-proposal conferences, and one-on-one meetings with the contracting officer or program manager are common during this period. These interactions are governed by procurement integrity rules, but within those bounds, they are the most effective way to understand what the government actually needs (as opposed to what the solicitation document says).
The pre-solicitation phase is also where teaming decisions crystallize. For contracts requiring capabilities beyond a single company’s scope, prime-subcontractor relationships and joint ventures form during this window. Waiting until the RFP is final to begin teaming conversations typically means the strongest partners are already committed.
Phase 3: The Solicitation (RFP Release)
The formal Request for Proposal is the government’s binding statement of what it wants to buy, how it will evaluate offers, and on what terms the contract will be awarded. For negotiated procurements under FAR Part 15, the RFP contains several critical elements that directly determine who wins.
Section L (Instructions to Offerors) specifies exactly what the proposal must contain, its format, page limits, and submission requirements. Non-compliance with Section L is one of the most common reasons proposals are eliminated before evaluation begins. If the RFP says 50 pages and you submit 52, the evaluators may not read pages 51 and 52.
Section M (Evaluation Criteria) defines how the government will score proposals. Under FAR 15.304, every solicitation must evaluate three mandatory factors: price or cost to the government, quality of product or service, and past performance. Quality factors may include technical excellence, management capability, personnel qualifications, prior experience, and compliance with solicitation requirements.
Critically, Section M must disclose the relative importance of these factors. The solicitation will state whether all non-cost evaluation factors, when combined, are “significantly more important than, approximately equal to, or significantly less important than cost or price.” This single sentence determines the entire competitive dynamic. When technical factors dominate, innovative solutions with higher price tags can win. When cost dominates, the competition becomes a race to the bottom.
The proposal response period is governed by FAR 5.203, which requires a minimum of 30 days (45 days when expanding small business opportunities). Complex procurements may allow 60 to 90 days. But proposal development for a competitive FAR Part 15 procurement typically consumes the entire response window, and companies that have not been tracking the opportunity since the RFI stage are at a severe disadvantage.
Phase 4: Evaluation and Competitive Range
After proposals are submitted, the government’s evaluation team scores each submission against the Section M criteria. The evaluation mechanics vary depending on which source selection approach the solicitation uses.
Best Value Tradeoff
Under the tradeoff process, the government may award to other than the lowest-priced offeror if the perceived benefits of a higher-priced proposal merit the additional cost. The Source Selection Authority (SSA) conducts a comparative assessment of all proposals against the evaluation criteria and documents the rationale for any tradeoff between cost and non-cost factors.
This is the standard approach for complex services and systems, and it is where proposal quality matters most. The SSA’s decision must represent independent judgment based on a comparative assessment of proposals against all solicitation criteria. While the SSA may use reports and analyses prepared by the evaluation team, the decision is personal and documented.
The FY2017 NDAA restricted the use of LPTA for DoD contracts, prohibiting it for knowledge-based professional services, contracts predominantly for personnel, auditing services, and procurements where innovation is a meaningful evaluation factor. This shifted a meaningful share of DoD procurements toward tradeoff evaluations where technical quality and innovation can differentiate competitors.
Lowest Price Technically Acceptable (LPTA)
Under LPTA, non-cost factors are evaluated on a pass/fail basis. Every proposal that meets the technical threshold is considered “acceptable,” and the award goes to the lowest-priced acceptable offer. There is no tradeoff analysis, no premium for exceeding requirements.
LPTA is used primarily for commoditized products and well-defined services where requirements are stable and innovation adds limited value. For small businesses competing on capability rather than scale, LPTA procurements are typically unfavorable terrain.
Competitive Range and Discussions
After initial evaluation, the contracting officer may establish a competitive range that includes only the most highly rated proposals. Offerors outside the competitive range are notified and excluded from further consideration.
Discussions with offerors in the competitive range are tailored to each proposal. The contracting officer identifies deficiencies, significant weaknesses, and adverse past performance information, giving each offeror an opportunity to revise its proposal. The primary objective of discussions is to maximize the government’s ability to obtain best value.
For companies new to federal contracting, the discussion phase is counterintuitive. The government is telling you what is wrong with your proposal and giving you a chance to fix it. Companies that treat discussions as adversarial rather than collaborative consistently underperform.
Phase 5: Award and Debriefing
The SSA makes the final selection and the contracting officer issues the award. Unsuccessful offerors are entitled to a debriefing that explains the evaluation ratings, the rationale for the award decision, and the relative standing of the offeror’s proposal.
Debriefings are not consolation prizes. They are the single most valuable source of competitive intelligence available to contractors. A thorough debriefing reveals exactly how the evaluation team scored each factor, where the proposal was weak, and what the winning offeror did better. Companies that systematically incorporate debriefing feedback into their next proposal improve their win rates over time.
Timelines: How Long This Actually Takes
The full acquisition cycle, from the first market signal to a signed contract, is measured in months and often years.
DoD-wide median Procurement Administrative Lead Time (PALT), measured from solicitation to award, decreased from 41 days in FY2019 to 32 days in FY2022. That improvement, however, masks a divergence by contract value. For contracts over $50 million, PALT actually increased by 70 days over the same period. Over 85% of definitive contracts were below $10 million, which compressed the aggregate median.
The PALT metric also captures only a fraction of the total cycle. The pre-solicitation phase (RFI, sources sought, draft RFP, industry days) adds 3 to 12 months. Requirements development adds another 6 to 12 months. For major defense acquisition programs, GAO found that the average time to deliver initial capability has reached almost 12 years, up 18 months from the prior year.
GAO’s 2025 assessment of defense acquisition reform found that DoD remains embedded in a “traditional linear acquisition structure” with rigid, sequential processes that develop requirements to fixed specifications set years in advance, risking delivery of systems that are “already obsolete” by the time they reach the warfighter.
For small contractors pursuing contracts in the $1 million to $50 million range, a realistic timeline from first engagement to contract award is 6 to 18 months, assuming the contractor was tracking the opportunity from the RFI stage. Companies that discover opportunities at the RFP stage and attempt to compete cold are compressing 12 months of positioning into a 30-day proposal response window.
FAR Part 12: The Commercial Alternative
Not every DoD procurement runs through the Part 15 negotiated process. FAR Part 12 implements a preference for acquiring commercial products and commercial services, with streamlined procedures that bypass the formal evaluation frameworks of Part 15.
Under Part 12, commercial acquisitions are not subject to the structured source selection process described above. Evaluation can use simplified procedures: a request for quotations followed by a purchase order, without competitive range determinations, formal discussions, or adjectival ratings. The contracting officer has broader discretion and the process moves faster.
FAR Part 12 was recently rewritten and reorganized by acquisition timeline (pre-solicitation, solicitation and evaluation, post-award), cutting almost one-third of the original text. The revision reflects a broader push to make commercial buying easier.
For technology companies with commercial products that have defense applications, the Part 12 pathway is significantly more accessible than Part 15. The proposal burden is lighter, the timeline is shorter, and the evaluation focuses on demonstrated commercial capability rather than bespoke compliance documentation.
Other Transaction Authority: The Bypass
The fastest-growing alternative to the traditional acquisition process is Other Transaction Authority (OTA). OTAs are not contracts in the FAR sense. They are agreements authorized by 10 U.S.C. 4022 that allow DoD to negotiate directly with companies, including nontraditional defense contractors, without the constraints of the FAR.
OTA spending has grown from $1.56 billion in FY2016 to $18.36 billion in FY2024, a roughly tenfold increase. DoD executed 7,409 OT actions in FY2024, a fourfold increase in actions since FY2019. Ninety-three percent of FY2024 OTA obligations were awarded to contractors with significant participation by nontraditional defense contractors, and 61% of prototype projects included or enabled follow-on production.
The acquisition reform trajectory reinforces this shift. An April 2025 executive order directed a comprehensive overhaul of the DoD acquisition system, emphasizing “speed, flexibility, and execution” and establishing a preference for commercial solutions. In November 2025, Secretary Hegseth redesignated the Defense Acquisition System as the “Warfighting Acquisition System”, mandating documentation reduction to statutory minimums, delegation to Military Departments, and replacement of traditional analyses of alternatives with competitive prototyping.
For companies with innovative technologies and limited FAR experience, OTA consortia represent the most accessible on-ramp to defense work. The tradeoff is that OTAs require a different engagement model: consortium membership, rapid prototype proposals, and the ability to deliver working technology on compressed timelines.
GAO Protests: The Accountability Mechanism
Any offeror that believes the government violated procurement law or regulation in awarding a contract can file a bid protest with the Government Accountability Office. In FY2025, GAO received 1,688 protest cases, down 6% from FY2024’s 1,803 filings.
The headline numbers are instructive. GAO sustained 53 protests on the merits in FY2025, a sustain rate of 14%. But the overall effectiveness rate was 52%, meaning protesters obtained some form of relief (agency corrective action, GAO sustain, or settlement) in more than half of cases. The gap between the 14% sustain rate and the 52% effectiveness rate reflects a well-known dynamic: agencies frequently take voluntary corrective action rather than defend a flawed evaluation on the merits.
For small contractors, protests serve two functions. First, they are a real enforcement mechanism. If the government evaluates your proposal unfairly or violates its own stated criteria, a GAO protest can result in corrective action, re-evaluation, or a new award decision. Second, the existence of the protest mechanism disciplines the evaluation process itself. Contracting officers who know their source selection decisions may face GAO scrutiny tend to document their rationale more carefully.
Filing a protest requires understanding the procedural rules (strict filing deadlines, standing requirements, scope limitations) and the substantive standards GAO applies. The protest is not a second chance to submit a better proposal. It is a legal challenge to specific errors in how the government conducted the procurement.
The Mistakes That Cost Small Contractors
Several patterns recur among small businesses that consistently lose federal competitions.
Discovering opportunities too late. The proposal response period is the wrong time to start competing. Companies that first engage during the RFI or sources sought phase, build program office relationships, shape requirements through draft RFP comments, and form teaming arrangements before the solicitation drops win at higher rates than companies that respond cold.
Ignoring Section M. Proposals that do not mirror the evaluation criteria, factor by factor, subfactor by subfactor, force evaluators to hunt for relevant information. Evaluators will not do your organizational work for you. If Section M lists five subfactors, your proposal should have five clearly labeled sections that map directly to those subfactors.
Underinvesting in past performance. For procurements above the simplified acquisition threshold ($250,000), past performance must be evaluated. Companies without relevant past performance are not disqualified, but they receive a “neutral” rating that provides no competitive advantage. Building past performance through subcontracting, OTA participation, SBIR awards, and GSA schedule orders is a deliberate, multi-year strategy, not something that can be improvised at proposal time.
Treating price as an afterthought. Even in best-value tradeoff procurements, the SSA must justify paying a premium for a higher-rated, higher-priced proposal. A technically superior proposal that costs 40% more than the next-best offer creates a difficult tradeoff decision. Realistic, defensible pricing that reflects actual cost estimates rather than aspirational margins improves the probability that technical superiority converts to an award.
Skipping the debrief. Companies that do not request debriefings after losses forfeit the most direct feedback the government will ever provide about their competitive positioning. Debriefing insights compound over time. The companies that win consistently are the ones that have lost, learned, and adapted.
The System Is Learnable
The DoD acquisition cycle is complex. It is slow. It is burdened by regulations that even seasoned professionals find unwieldy. GAO’s own assessment concludes that the system remains trapped in a rigid, sequential structure that prioritizes process compliance over rapid capability delivery.
But the system is also deterministic. The evaluation criteria are published. The process is governed by statute and regulation. The appeal mechanism is accessible. Unlike commercial sales, where relationships and brand recognition can substitute for product superiority, federal procurement runs on documented, auditable criteria that any company can learn to address.
The companies that succeed in defense acquisition are not the ones with the best technology or the lowest prices in isolation. They are the ones that understand how the system evaluates them and build their proposals, their teams, and their market positioning around that understanding.
The acquisition cycle rewards preparation over improvisation, persistence over brilliance, and institutional knowledge over individual heroics. The first step is understanding that the cycle begins at the RFI, not the RFP, and that the companies positioned to win the award were working the opportunity months before the solicitation ever appeared.
