Request for Proposal (RFP): How to Read and Respond
A Request for Proposal is the primary competitive solicitation instrument the federal government uses when it needs more than just a price — it needs a contractor's technical approach, qualifications, and management plan evaluated alongside cost. Understanding how RFPs are structured, what evaluators actually score, and how a proposal maps back to stated requirements determines whether a response is competitive or disqualified before review. This page covers RFP anatomy, the evaluation process, common solicitation scenarios, and the decision logic contractors use when choosing whether and how to bid.
Definition and Scope
An RFP is a formal solicitation document issued under the Federal Acquisition Regulation (FAR), specifically governed by FAR Part 15, which covers contracting by negotiation. Unlike an Invitation for Bids (IFB), where award goes automatically to the lowest responsive, responsible price, an RFP allows the government to conduct a best-value tradeoff — weighing technical merit, past performance, and price against each other according to factors stated in the solicitation itself.
RFPs are used across the full spectrum of federal procurement: defense, civilian agency IT, professional services, research and development, and construction projects exceeding the simplified acquisition threshold, which FAR 2.101 sets at $250,000 for most acquisitions. Solicitations appear on SAM.gov, the central federal contract opportunities portal managed by the General Services Administration (GSA).
An RFP is distinct from two other solicitation types contractors encounter on the broader government contracting landscape:
- Request for Quotation (RFQ): Used for simplified acquisitions below $250,000 or for orders against existing vehicles such as GSA Schedules; responses are quotations, not offers.
- Request for Information (RFI): Market research tool only — no award results from an RFI response.
How It Works
An RFP is organized into sections labeled by letter under the Uniform Contract Format (UCF), defined in FAR 15.204. The sections most critical to proposal preparation are:
- Section C — Statement of Work (SOW) or Performance Work Statement (PWS): Defines exactly what the contractor must deliver. Every proposal volume should trace directly back to Section C requirements.
- Section L — Instructions to Offerors: Specifies page limits, volume structure, file formats, submission deadlines, and any mandatory certifications.
- Section M — Evaluation Factors and Subfactors: States the criteria evaluators will apply and whether factors are listed in descending order of importance. FAR 15.304 requires that price or cost be evaluated in every source selection.
- Section H — Special Contract Requirements: Contains agency-specific clauses — cybersecurity compliance references, small business subcontracting plan requirements under FAR 19.702, or DFARS compliance requirements for defense solicitations.
- Section K — Representations and Certifications: Mandatory attestations about business size, ownership, legal status, and registrations such as a current SAM registration.
The evaluation process after submission proceeds through three standard phases under FAR 15.305:
- Initial review: Compliance check against Section L — missing volumes, excess page counts, or absent certifications can render a proposal technically unacceptable without substantive review.
- Individual evaluator scoring: Technical evaluation panel members score each subfactor independently against adjectival ratings (Outstanding, Good, Acceptable, Marginal, Unacceptable) or a numerical scale specified in the source selection plan.
- Source selection decision: The Source Selection Authority (SSA) — not the contracting officer in most major acquisitions — makes the final best-value determination, documented in a Source Selection Decision Document.
Offerors who are not selected have the right to request a written debriefing within 3 days of receiving notice of award, per FAR 15.506. A debriefing covers strengths, weaknesses, and deficiencies identified in the proposal and is the primary feedback mechanism available before a bid protest.
Common Scenarios
Competitive Range and Discussions: On complex acquisitions, the contracting officer may establish a competitive range of the most highly rated proposals and open written discussions — called Exchanges — before requesting Final Proposal Revisions (FPRs). FAR 15.306 governs this process. Proposals outside the competitive range are eliminated without proceeding to final evaluation.
Multiple-Award IDIQ RFPs: A significant share of federal RFPs are issued to establish Indefinite Delivery/Indefinite Quantity (IDIQ) contracts with multiple awardees. The base RFP establishes pool membership; individual work is then awarded through task orders. Winning the base IDIQ does not guarantee revenue — subsequent task order competitions are required.
Small Business Set-Aside RFPs: When a small business set-aside applies, only firms meeting the applicable NAICS code size standard may submit. Socioeconomic program set-asides — including 8(a), HUBZone, and SDVOSB — further restrict the eligible offeror pool and typically reduce proposal volume.
Research and Development RFPs: Broad Agency Announcements (BAAs) and R&D solicitations follow a modified process under FAR 35.016, where technical merit outweighs price and white papers may substitute for full proposals in the first stage.
Decision Boundaries
Before committing proposal resources, contractors typically apply a bid/no-bid framework anchored to four questions:
- Requirement alignment: Does the firm hold demonstrated, documentable capability matching the PWS or SOW tasks? Gaps that cannot be addressed through teaming or subcontracting are disqualifying.
- Competitive position: Is there a realistic path to an "Outstanding" or "Good" rating on the highest-weighted technical factors in Section M? If an incumbent contractor holds all relevant past performance ratings, a new entrant's probability of award drops substantially.
- Price-to-win feasibility: Can the firm build a cost proposal that is both realistic under cost accounting standards and competitive against likely competitor pricing?
- Compliance burden: Does the RFP require active security clearances (security clearance requirements), a mandatory subcontracting plan (subcontracting plans requirements), or CMMC certification (Cybersecurity Maturity Model Certification) that the firm cannot satisfy before proposal submission?
The distinction between a deficiency and a weakness in federal source selection controls how much damage a proposal flaw causes. Under FAR 15.001, a deficiency is a material failure to meet a government requirement — it can render a proposal unacceptable outright. A weakness is a flaw that increases the risk of unsuccessful performance but does not eliminate the proposal from consideration. Proposals must eliminate all deficiencies before discussions close; weaknesses are managed through the scoring tradeoff.
