Reading PSC Data
How to evaluate a federal market by PSC
PSC identifies the contractor product or service associated with an award action. Read obligations together with action frequency, active fiscal years, customer breadth, and recent activity before treating a classification as an addressable market.
Follow the customers
Federal customer count shows whether demand is concentrated in a narrow buyer set or distributed across government.
Validate current relevance
Latest activity helps separate active federal markets from classifications that primarily describe older contract history.
