====== Maintainability Criterion ====== [[public:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]] ===== Discussion ===== A Maintainability Criterion establishes a measurable condition used to evaluate the [[public:99_annexes:annex-b-terms-and-definitions:m:maintainability|Maintainability]] of an entity. A Maintainability Criterion may specify: * A threshold * A tolerance * An acceptable range * A required property * A permitted maintenance duration * A maximum change effort * A dependency-visibility condition * A change-isolation condition * A verification or regression-testing condition The applicable Maintainability Criteria may originate from a [[public:99_annexes:annex-b-terms-and-definitions:r:requirement|Requirement]], [[public:99_annexes:annex-b-terms-and-definitions:p:policy|Policy]], [[public:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]], profile, [[public:99_annexes:annex-b-terms-and-definitions:b:baseline|Baseline]], or designated [[public:99_annexes:annex-b-terms-and-definitions:a:authority|Authority]]. ===== Definition ===== //measurable condition used to determine whether the maintainability of an entity satisfies a specified requirement// ===== Source ===== Dido Solutions, Inc. and Jackrabbit Consulting, Inc., derived from the maintainability concepts in ISO/IEC 25010:2023 ===== Note ===== A Maintainability Criterion states the condition used for evaluation. It does not state the measured or observed result of that evaluation. A criterion may address modularity, reusability, analyzability, modifiability, testability, or another governed maintainability characteristic. When applicable Maintainability Criteria conflict, DIDO-TE records and surfaces the conflict without inventing precedence. The appropriate Community of Interest or designated Authority resolves the conflict. ===== Example ===== A requirement that an authorized configuration change be implemented and regression tested within four hours establishes a Maintainability Criterion containing a maximum maintenance duration and a verification condition. ---- © 2026 Dido Solutions, Inc. and Jackrabbit Consulting, Inc.
