toimintoperusteisia

Toimintoperusteisia is an adjectival form used in Finnish to describe things that are based on how an operation or function is performed. The term comes from the compound "toiminto" (operation, function) and the suffix "perusteinen" (based on, founded on), with the plural partitive ending "-isia" used to modify plural nouns in contexts such as measures, criteria, or principles.

Grammatically, toimintoperusteinen is an attributive adjective. Its form toimintoperusteisia is used when describing plural nouns in partitive or certain other grammatical contexts, for example "toimintoperusteisia mittareita" (operationally based metrics) or "toimintoperusteisia vaatimuksia" (operationally based requirements). The expression is typical of formal or technical Finnish and is common in business, IT, production, and policy discourse.

Usage and nuance: toimintoperusteisia is used to distinguish assessments, criteria, or plans that anchor themselves in the functioning and performance of processes rather than in abstract inputs, theoretical assumptions, or purely financial figures. It emphasizes how operations are carried out and evaluated. For instance, "Toimintoperusteisia mittareita käytetään arvioimaan prosessien suorituskykyä," meaning metrics grounded in actual process performance.

Related terms include toiminnallinen (functional), tulospohjainen or tulosperusteinen (outcome-based), and perusperiaatteisiin perustuva (based on core principles). In Finnish, toimintoperusteisia is a technical—yet increasingly common—way to express that analysis or planning is rooted in operational realities.
