• SBA programs (8(a), HUBZone, SDVOSB, WOSB) are federal certifications for federal contracts only — state certifications are separate.
• DCAA, DCMA, and ACO are the government-side contract oversight functions — understanding their roles helps you anticipate government requirements.
• GWAC vehicles (OASIS+, CIO-SP4, 8(a) STARS III) are essential for access to the largest task order competitions — position on a vehicle before you need it.
• Bookmark this glossary — come back to it whenever you encounter an unfamiliar term in a solicitation or contract.
