feilbasert

Feilbasert is a Norwegian adjective meaning based on faults or errors. It is used to describe methods, analyses, or systems that center on identifying, understanding, and addressing faults or mistakes. The term functions as a descriptive label rather than a formal theory, signaling a problem-oriented approach.

The expression appears across various domains, including engineering, software development, quality assurance, and diagnostics. Common constructions include feilbasert tilnærming (fault-based approach), feilbasert analyse (fault-based analysis), and feilbasert diagnostikk (fault-based diagnostics). In usage, feilbasert is typically contrasted with other paradigms such as data-drevet (data-driven) or regelbasert (rule-based) approaches.

Etymologically, feilbasert is a compound of feil (fault, error) and basert (based), reflecting its meaning. Its interpretation is context-dependent: in one setting it may emphasize fault detection and correction, in another a fault-centered reasoning process. While widely understood in Norwegian, it is not tied to a single standardized theory; rather, it serves as a flexible descriptor for approaches that foreground faults and corrective action. In English translations, feilbasert is commonly rendered as “fault-based” or “error-based,” depending on the domain being described. Related concepts include feilidentifikasjon (fault identification) and rotårsaksanalyse (root-cause analysis).
