Use the filters in two stages. The first stage eliminates noise quickly. The second ranks the survivors by probability of win.
Phase 1: Hard-gate filters
1. Capability / core offering
Can you prove you have done substantially similar work? If not, a keyword match is irrelevant. Look for referenceable past performance, relevant personnel, technical capability and delivery capacity.
2. Set-aside / eligibility
Verify whether you are legally eligible for the acquisition. Check the stated set-aside and applicable socioeconomic status. SBA explains how NAICS-based size standards determine whether a business qualifies as small.
3. Place of performance
Check geography, onsite requirements, travel, security or facility needs, staffing availability and whether the delivery model preserves your margin.
4. PSC
Product and Service Codes describe what the government is buying—the product, service or research activity. They can be more precise than broad industry searches.
5. NAICS
NAICS identifies the industry classification under which the government is buying. Confirm that the NAICS aligns with your registration and the applicable SBA size standard.
Use SBA's contracting guidance and size-standard information to verify current requirements. Size standards vary by NAICS.
Phase 2: Strategic-priority filters
6. Agency and past buyer behavior
Ask whether this agency, subagency or buying office actually buys this type of work from businesses like yours. Which vehicles dominate? Does the office use small-business set-asides or route work through large GWACs and primes?
7. Recompete and incumbent position
Identify the incumbent, contract history, modifications, performance signals, contract end date, vehicle and possible vulnerabilities. A recompete is attractive only when the competitive position is credible.
8. Contract value / magnitude
The contract should fit your financial and delivery capacity. A useful internal planning heuristic is to compare the opportunity with the scale of your strongest completed contracts. This is a business rule of thumb, not a federal rule.
9. Opportunity type / acquisition stage
Separate Sources Sought, RFIs and draft RFPs from final solicitations. Early signals can create time to research, team and engage before requirements are locked.
10. Keywords—last
Use keywords after the structural filters are in place. Government terminology can differ from commercial terminology, so keyword variations should support—not replace—NAICS, PSC, agency and award-data analysis.
