Funktionstniveau
Funktionstniveau, in German-language engineering and design literature, refers to the abstraction level at which a function of a system is defined, analyzed, and validated. The term signals how detailed the description of a function is, including inputs, outputs, interfaces, and performance constraints. The concept supports hierarchical decomposition of complex systems by allowing stakeholders to agree on a progressive granularity rather than on a single, monolithic specification.
The term is used in requirements engineering, system architecture, and safety and reliability analyses to structure
Levels are context-dependent and not standardized across industries. A common, illustrative scheme uses several layers: Level
