It describes phenomena, data, processes, or signals that can be detected by an observer, either directly through senses or via instrumentation. The noun form is Beobachtbarkeit, or observability in English, and the related noun Beobachter refers to an observer.

In science and philosophy, beobachtbar denotes quantities or events that are accessible through observation or measurement.

In control theory and systems engineering, Beobachtbarkeit is a formal property of a dynamical system. A system
