What Does OAT Stand For?
OAT stands for Operational Acceptance Test
Operational Acceptance Test (OAT) is a critical phase in the software development lifecycle that evaluates a system's operational readiness and performance under real-world conditions. The primary objective of OAT is to ensure that the solution meets business requirements, complies with operational standards, and functions effectively within the existing IT infrastructure. This testing phase typically involves assessing the system's stability, reliability, security, and usability, ensuring that it can be deployed smoothly and efficiently in a live environment. Successful completion of OAT is essential for gaining stakeholder approval and moving forward with production deployment.
