10 / Market Interpretation

How should contractors evaluate this market?

01

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.

02

Follow the actual buyers

Move from federal customers to contracting offices. Offices reveal where acquisition responsibility and recurring purchasing activity are concentrated.

03

Measure accessible demand

Use competition, small-business participation, incumbent vendors, and PSC mix before treating the full $1.00B market as addressable.
