The Federal Acquisition Lifecycle — The 10 Phases of a Government Contract

Every federal contract travels the same road, from the day an agency realizes it needs something to the day the contract is closed out. Learn the ten phases and you can see where you are — and where the leverage is. The set-aside that decides whether you can compete is shaped in the first four phases, long before anything posts to SAM.gov; the competition is won on paper in the solicitation and proposal phases; and the track record that wins your next contract is built during performance and closeout. These plain-English pages take one phase at a time, each with an at-a-glance card, its controlling FAR citation, what happens, what to do, and the SDVOSB angle — the map that ties together the solicitation types, source-selection methods, roles, forms, clauses, protest forums, glossary, FAQ, and calculators.

LaunchedPublished the federal acquisition lifecycle phases reference covering the ten phases a federal contract moves through — acquisition planning (FAR Subpart 7.1), market research (FAR Part 10), requirements definition (FAR Part 11 / 37.6), the set-aside decision and the rule of two (FAR Subpart 19.5 / 19.1405 / 19.1406), the synopsis and solicitation (FAR Part 5 / Parts 12–15), proposal preparation and submission (FAR 15.208), evaluation and source selection (FAR Subpart 15.3), award and debriefing (FAR Subpart 15.5 / Part 33), contract administration (FAR Part 42), and contract closeout (FAR Subpart 4.8) — each with an at-a-glance quick-facts card, a what-happens list, a key-activities table, an SDVOSB-specific angle, a what-to-do checklist, watch-outs, FAQPage, Article, Dataset, and BreadcrumbList structured data, primary-source FAR citations, and cross-links into the glossary, how-to guides, FAQ, solicitation types, source-selection methods, roles, forms, clauses, protest forums, and the set-aside eligibility, size-standard, win-probability, price-to-win, limitations-on-subcontracting, and subcontracting-goal calculators.

Before the Solicitation

Acquisition PlanningThe earliest phase, where the agency decides what it needs, how it will compete the buy, and on what schedule — usually months before anything posts to SAM.gov and the best time for a small business to get on the radar.

Market ResearchThe phase where the government tests the market to learn who can meet the need, at what price, and whether enough capable small businesses exist to justify a set-aside — the evidence base for the rule of two.

Requirements DefinitionThe phase where the agency turns its need into the actual work document — the statement of work, performance work statement, or statement of objectives — plus the specifications, standards, and delivery schedule that a proposal must satisfy.

The Set-Aside DecisionThe go/no-go decision that decides who may compete — whether the buy is set aside for small business or a socioeconomic program (SDVOSB, WOSB, HUBZone, 8(a)), competed full-and-open, or awarded sole-source — driven by the rule of two.

Soliciting & Competing

Synopsis & SolicitationThe phase where the requirement finally goes public — the presolicitation synopsis on SAM.gov followed by the solicitation itself (an RFP, RFQ, or IFB) that states the work, the terms, and how proposals will be evaluated.

Proposal Preparation & SubmissionThe offeror-side phase where you build the proposal the solicitation asked for — the technical, past-performance, and price volumes — comply with the instructions in Section L, and get it in before the deadline, because a late offer is generally rejected.

Evaluation & Source SelectionThe phase where the government grades every proposal against the stated evaluation factors, may establish a competitive range and hold discussions, and selects the offer that represents the best value — the heart of a negotiated procurement.

Award & Performance

Award & DebriefingThe phase where the contracting officer notifies offerors, makes the award, and — on request — debriefs the losers; it also opens the short, strictly enforced window in which a disappointed offeror can protest.

Contract AdministrationThe longest phase — where you actually perform the work, invoice and get paid, process modifications and options, and are rated in CPARS — and where SDVOSB obligations like the limitations on subcontracting are measured over performance.

Contract CloseoutThe final phase, where a physically complete contract is administratively closed — final deliverables accepted, final invoice and any indirect-rate settlement processed, property and records dispositioned, and the file closed.
