Funktionsbereit

Funktionsbereit is a German term used to describe a component, system or device that is prepared to perform its intended function and is ready for use. The designation implies that necessary preparation steps have been completed, such as configuration, testing, calibration, documentation, and, where relevant, training or instruction.

The term is common in engineering, manufacturing, procurement, IT, and service management. It serves as a status marker in project workflows and supply chains, indicating that a unit or module has passed required checks and can operate under defined conditions.

Criteria for being deemed funktionsbereit vary by context but typically include functional tests showing expected performance, proper configuration, safety and quality checks, and the availability of user manuals and maintenance information. In software, it can mean that a module is installed, configured, and has passed unit and integration tests; in hardware, that calibration and verification procedures are complete; in logistics, that the item is packaged and ready for deployment or shipment.

Relationship to related terms: funktionsbereit differs from funktionsfähig (currently capable of functioning) and from einsatzbereit (ready for deployment in the field). It is also distinct from inbetriebnahme, the process of bringing equipment into operation, and from its broader concept, funktionsbereitschaft, the state of readiness.

Examples include a laboratory instrument certified as funktionsbereit after functional testing, or a software feature marked as funktionsbereit once it is tested and released to production.
