The Short Answer
The five phases of the federal contract life cycle are:
Planning -- The government identifies needs, develops requirements, and conducts market research
Solicitation -- The opportunity is posted publicly and vendors prepare proposals
Evaluation -- The government reviews proposals against stated criteria
Award -- The winning contractor is selected and the contract is executed
Administration -- The contract is performed, managed, and eventually closed out
Each phase has specific actions, timelines, and opportunities for contractors. The earlier you engage, the better your win probability.
Phase 1: Planning (6-18 Months Before Award)
What the government does:
Identifies the requirement (the "need")
Develops the Statement of Work (SOW) or Performance Work Statement (PWS)
Conducts market research to identify potential sources
Determines contract type (FFP, T&M, cost-plus)
Establishes the Independent Government Cost Estimate (IGCE)
Issues Sources Sought notices or RFIs (Requests for Information)
What smart contractors do:
Respond to Sources Sought/RFIs -- This shapes the requirement before it is finalized
Attend Industry Days -- Direct access to the program office and contracting officer
Build relationships with the end user and contracting team
Conduct capture -- Research the incumbent, understand the budget, map the evaluation criteria
Win probability impact: Contractors who engage during Planning have a 40-60% win rate. Those who first see the opportunity at Solicitation have a 5-15% win rate.
Phase 2: Solicitation (30-90 Days)
What the government does:
Posts the solicitation on SAM.gov (RFP, RFQ, or IFB)
Defines evaluation criteria and factors
Establishes the proposal submission deadline
Answers vendor questions (usually via formal Q&A amendments)
May hold pre-proposal conferences
What smart contractors do:
Download and analyze the solicitation immediately -- Time is your enemy
Make a Go/No-Go decision within 48 hours
Submit clarifying questions to shape the government's understanding
Write a compliant, compelling proposal that addresses every evaluation factor
Price competitively based on the evaluation method (LPTA vs Best Value)
Key timelines:
Solicitation Type
Typical Response Window
RFQ (simplified)
7-30 days
RFP (negotiated)
30-60 days
IFB (sealed bid)
30-45 days
IDIQ task order
10-21 days
Phase 3: Evaluation (30-120 Days)
What the government does:
Evaluates proposals against published criteria
Conducts technical evaluations (often by a Source Selection Evaluation Board)
Performs price analysis and cost realism checks
May request clarifications, exchanges, or Final Proposal Revisions (FPRs)
Documents the source selection decision
What smart contractors do:
Wait (there is little you can do during evaluation)
Be responsive if the government requests clarifications
Prepare for oral presentations if required
Do not contact the contracting officer about evaluation status (this can disqualify you)
Evaluation methods:
Method
How It Works
Your Strategy
LPTA (Lowest Price Technically Acceptable)
Lowest price wins among technically acceptable proposals
Price as low as possible while meeting minimum technical requirements
Best Value Trade-Off
Government weighs technical quality against price
Demonstrate superior technical approach; price is important but not dominant
Phase 4: Award (1-30 Days)
What the government does:
Selects the winning contractor
Notifies unsuccessful offerors (via FAR 15.503)
Provides a debriefing to unsuccessful offerors (if requested)
Publishes the award on SAM.gov and FPDS
Executes the contract document
What smart contractors do:
If you win: Review the contract for accuracy, establish the project team, schedule kickoff
If you lose: Request a debrief within 3 days of notification. Debriefs tell you exactly why you lost.
Consider a protest if you believe the evaluation was flawed (GAO protest window is 10 days post-debrief for negotiated procurements)
Phase 5: Administration (1-10 Years)
What the government does:
Manages contract performance through a Contracting Officer's Representative (COR)
Processes modifications, change orders, and options
Conducts performance evaluations (CPARS)
Manages invoicing and payments
Closes out the contract at completion
What smart contractors do:
Deliver exceptional performance -- Your CPARS rating determines your future win rate
Manage scope carefully -- Do not perform out-of-scope work without a modification
Track option periods -- Position for option exercise and eventual recompete
Build the recompete case -- Start preparing for re-competition 18 months before contract end

FAQ
What are the 5 phases of the contract life cycle?
The five phases are Planning (need identification and market research), Solicitation (opportunity posted and proposals prepared), Evaluation (government reviews proposals), Award (winner selected and contract signed), and Administration (performance, management, and closeout). The full cycle from planning to award takes 6-24 months. Administration can last 1-10+ years.
What are the 3 C's of a contract?
The 3 C's of a contract are Consideration (something of value exchanged), Capacity (parties have legal authority to enter the agreement), and Consent (mutual agreement to the terms). In federal contracting, these are established through the solicitation, proposal, and award process governed by the Federal Acquisition Regulation (FAR).
