An operational definition specifies a concept or measurable quantity by stating the exact operations, procedures, or measurements used to observe, quantify, or apply it. It replaces abstract description with repeatable procedure, so that different observers produce consistent results. Parameters: the concept being defined (the what), the operations prescribed (the how), and the criteria for observation (the when). Persistence mechanism: documented procedure, institutional training, and repeated cross-validation across applications.

Definition
Why it is in scope
A human-made method for defining abstract concepts by specifying the exact operations, procedures, or measurements used to identify and quantify them. It persists through scientific practice, methodological standards, and institutional protocols that require concepts to be rendered testable and observable.

An operational definition IS a specific kind of methodology — a methodological approach for rendering abstract concepts testable through specified operations and measurements. Per Law 9, a competent speaker would call an operational definition 'a kind of methodological tool.' Direction specific→general is correct.

Remove measurement — does operational-definition stop operating? Yes. An operational definition defines how to measure a concept; without the measurement function, it has no purpose. The removal test passes.
