A small business label does not guarantee a defense award. Connect the company’s representation, the acquisition approach, and any subcontracting commitment to the specific program and supporting record.
This guide explains DFARS Part 219: Small Business Programs. Read the relevant coverage with the FAR, applicable supplements and deviations, and the actual solicitation or contract.
Watch the DFARS Part 219 lesson
Separate business status from acquisition strategy
Part 219 supplements FAR small business programs. Section 219.201 includes defense small business specialist review and documentation on DD Form 2579 for covered acquisitions. That is a Government coordination process, not a contractor certification form. For pursuit planning, identify the actual solicitation and program instead of treating your company’s marketing description as proof of an acquisition decision.
Keep subcontracting commitments current
Section 219.704 requires written notice to the administrative contracting officer when a prime substitutes a firm that is not small for a small business specifically identified in its subcontracting plan. Notice occurs within a reasonable period after subcontract award. The rule does not prescribe a universal number of days. Keep the relevant plan, supplier change, and notification record connected.
Distinguish the DoD mentor-protege program
Subpart 219.71 addresses the DoD mentor-protege program, with application, acceptance, and participation procedures in Appendix I. Its structure includes qualifying participants, developmental assistance agreements, and specified reimbursement or credit arrangements. A teaming conversation is not an approved program agreement. Identify which program applies before promising a benefit, claiming credit, or describing the relationship in a proposal.
A hypothetical example
Consider a fictional defense electronics company building a pursuit plan with a larger prime. Its capability statement emphasizes small business status. The team also calls an informal teaming relationship a mentor-protege arrangement, while the prime’s buyer considers replacing a supplier named in its subcontracting plan.
Contracts separates the company representation, the solicitation’s acquisition approach, and the actual teaming documents. The prime checks whether the proposed replacement triggers a plan notification. Both teams identify which mentor-protege program they mean and whether the necessary participation and agreement records actually exist.
The teams can now describe the relationship and commitments more accurately. This example does not determine size status, establish set-aside eligibility, approve a mentor-protege agreement, or decide subcontracting credit. It demonstrates why a strong business-development story still needs a defensible record behind each claim.
Avoid the shortcut
Do not use small business status, an acquisition strategy, a subcontracting goal, and a mentor-protege relationship as interchangeable labels. Keep the evidence for each distinct. If a supplier or organizational fact changes, review the effect on the actual representation, plan, or agreement instead of recycling an earlier proposal statement.
Try this exercise
Review a fictional capability statement and teaming plan. Select one statement about small business participation and identify what it actually claims. Find the supporting representation, solicitation term, subcontracting plan, or approved program agreement. Flag any assertion that rests only on marketing language or an informal conversation.
