'''Operational acceptance testing''' ('''OAT)''') is used to conduct operational readiness (pre-release) of a product, service, or system as part of a [[quality management system]]. OAT is a common type of non-functional [[software testing]], used mainly in [[software development]] and [[software maintenance]] projects. This type of testing focuses on the [[operational readiness]] of the system to be supported, and/or to become part of the production environment. Hence, it is also known as '''operational readiness testing''' ('''ORT''') or [['''operations readiness and assurance]] testing''' ('''OR&A''') testing. [[Functional testing]] within OAT is limited to those tests which are required to verify the ''non-functional'' aspects of the system.

According to the International Software Testing Qualifications Board (ISTQB), OAT may include checking the [[backup]]/restore facilities, IT [[disaster recovery]] procedures, maintenance tasks and periodic check of security vulnerabilities.,<ref>ISTQB http://istqbexamcertification.com/what-is-acceptance-testing/</ref> and whitepapers on ISO 29119 and Operational Acceptance by Anthony Woods,<ref name="ISO 29119 OAT">{{cite paper|author=Anthony Woods|title=Operational Acceptance - an application of the ISO 29119 Software Testing standard|date=2015}}</ref> and ISO 25000 and Operational Acceptance Testing by Dirk Dach et al., OAT generally includes:<ref>White Paper: Operational Acceptance Testing, Business Continuity Assurance.
