käyttöönottotesti

Käyttöönottotesti, often translated as commissioning test or user acceptance testing (UAT) in English, is a critical phase in the implementation of a new system, software, or piece of equipment. Its primary purpose is to verify that the delivered solution meets the specified requirements and is ready for operational use by the end-users. This testing is typically conducted after system testing and integration testing have been completed, ensuring that all components work together as intended.

The core of a käyttöönottotesti involves the end-users themselves or their representatives actively using the system in a realistic environment. They perform predefined test scenarios and tasks that simulate their day-to-day operations. The goal is to identify any discrepancies between the expected behavior and the actual behavior of the system, uncovering bugs, usability issues, or unmet functional requirements that might have been missed in earlier testing stages.

Successful completion of a käyttöönottotesti signifies that the users have validated the system and are satisfied with its performance and functionality. This often leads to a formal sign-off, authorizing the transition of the system into production. If significant issues are found, they are documented, and the development team works to resolve them before a re-test is conducted. This iterative process ensures that the final deployed system aligns with the business needs and expectations of the organization.
