FAR (Federal Acquisition Regulation)
The FAR is the rulebook governing how US federal executive agencies buy: solicitation procedures, evaluation methods, contract types, and the clauses flowed into contracts. Proposal requirements that seem arbitrary usually trace to a FAR provision.
The FAR standardizes federal procurement end to end — how requirements are publicized, how discussions and BAFOs are conducted, what cost principles apply, which certifications offerors must make. Responders rarely read it cover to cover; they meet it through solicitation provisions and contract clauses incorporated by reference, agency supplements (like the DFARS for defense), and the procedural rhythms it imposes (protest windows, debriefing rights, source-selection formality). Practical literacy means recognizing high-consequence clauses — limitations on subcontracting in set-asides, cost-accounting triggers, data-rights assertions — and knowing that federal evaluators' seemingly rigid behavior is usually compliance, not preference. Commercial-item procedures (FAR Part 12) deliberately lighten the load.
