'''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'''). [[Functional testing]] within OAT is limited to those tests which are required to verify the ''non-functional'' aspects of the system.

OAT elaborates upon and compartmentalises operational aspects of acceptance testing.<ref>{{Cite web |title=atos-operational-acceptance-testing-whitepaper.pdf |url=https://atos.net/wp-content/uploads/2017/01/atos-operational-acceptance-testing-whitepaper.pdf |url-status=live}}</ref>.

According to the International Software Testing Qualifications Board (ISTQB), OAT may include checking the [[backup]]/restore facilities, IT [[IT disaster recovery|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 document|author=Anthony Woods|title=Operational Acceptance - an application of the ISO 29119 Software Testing standard|date=2015|publisher=Capgemini and Sogeti|pages=1-121–12}}</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.

* Component Testing

* Assess operability and supportability of the system.

For running the OAT [[test case (software)|test case]]s, the tester normally has exclusive access to the system or environment. This means that a single tester would be executing the test cases at a single point of time. For OAT the exact '''Operational Readiness''' quality gates are defined: both entry and exit gates. The primary emphasis of OAT should be on the operational stability, portability and reliability of the system.
