Itivät

Itivät is a theoretical term used to describe the degree to which the essential identity or functional continuity of a system is preserved through change. It is applied to a range of domains, including technical systems, organizations, and cognitive processes, where components may be updated, swapped, or reorganized while the overall behavior or meaning remains recognizable.

The term is a neologism that has appeared in interdisciplinary discussions about system integrity and continuity. It does not have a single fixed definition across fields; instead, authors generally frame it as a measure of how well a system retains its core characteristics despite transformation. Because it is a broad concept, itivät is often defined in relation to other ideas such as identity, coherence, and fidelity.

Definitions of itivät typically involve criteria such as output fidelity, functional behavior, and interpretability of results. Some scholars distinguish high itivät, indicating strong persistence of identity, from low itivät, where changes lead to noticeable shifts in meaning or function. The exact metrics are context-dependent and may rely on qualitative judgments, quantitative benchmarks, or a combination of both.

Applications of itivät appear in software engineering, where it may describe the extent to which new versions remain functionally equivalent for users; in organizational theory, where it can refer to the continuity of brand or corporate identity across restructurings; and in philosophy or cognitive science, where it can serve as a metaphor for personal or systemic continuity through change.

Related concepts include continuity, identity, and system integrity. Because itivät is a flexible, emerging term, discussions often emphasize context and purpose over universal, one-size-fits-all definitions.
