Definition
User acceptance testing is the final stage where the buyer verifies the delivered system meets the agreed acceptance criteria before sign-off and payment.
UAT is the buyer's last point of leverage: once you accept, the bargaining position shifts to the vendor. Tie acceptance to objective, pre-agreed criteria and withhold final payment until they're demonstrably met.
