Operationalization thus defines a fuzzy concept so as to make it clearly distinguishable, measurable, and understandable by empirical observation. In a broader sense, it defines the extension of a concept—describing what is and is not an instance of that concept. For example, in [[Medicine|medicine]], the phenomenon of health might be operationalized by one or more indicators like body mass index or tobacco smoking. As another example, in visual processing the presence of a certain object in the environment could be inferred by measuring specific features of the light it reflects. ## Key points - In research design, especially in psychology, social sciences, life sciences and physics, operationalization (or operationalisation) is a process of defining the measurement of a phenomenon which is not directly measurable, though its existence is inferred from other phenomena. - Operationalization thus defines a fuzzy concept so as to make it clearly distinguishable, measurable, and understandable by empirical observation. - In a broader sense, it defines the extension of a concept—describing what is and is not an instance of that concept. - For example, in medicine, the phenomenon of health might be operationalized by one or more indicators like body mass index or tobacco smoking. - As another example, in visual processing the presence of a certain object in the environment could be inferred by measuring specific features of the light it reflects. ## Relation to Systems Thinking Operationalization sits within the Systems Thinking cluster of related concepts. Its principles contribute to understanding [[Feedback|feedback]], [[Emergence|emergence]], and dynamic behavior in complex adaptive systems. ## Sources - [Operationalization — Wikipedia](https://en.wikipedia.org/wiki/Operationalization) Back to Systems Thinking ---  ## Semiotic profile > *The semiotic universals this article invokes, machine-derived from the crossref — **unverified** (born so).
