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

Measure accessible demand
Use competition, small-business participation, incumbent vendors, and PSC mix before treating the full $126.38M market as addressable.
