10 / Market Interpretation
How should contractors evaluate this market?
Start with the spending direction
Compare annual obligations with actions and vendor participation. Growth driven by only a few large actions represents a different opportunity from broad, recurring demand.
Follow the actual buyers
Move from federal customers to contracting offices. Offices reveal where acquisition responsibility and recurring purchasing activity are concentrated.
Measure accessible demand
Use competition, small-business participation, incumbent vendors, and PSC mix before treating the full $118.71M market as addressable.
