What you must do
Perform a cost or price analysis for every procurement transaction, including contract modifications, in excess of the simplified acquisition threshold; the method and degree of analysis depend on the facts (including considering potential workforce impacts where the transaction will displace public sector employees); as a starting point, make independent estimates before receiving bids or proposals.
When it applies
Any contract or contract modification above the SAT (FAR-based per 2 CFR 200.1; historically $250,000 — confirm current value at 48 CFR 2.101).
