Maintainability Criterion

Go to Terms and Definitions

A Maintainability Criterion establishes a measurable condition used to evaluate the 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 Requirement, Policy, Constraint, profile, Baseline, or designated Authority.

measurable condition used to determine whether the maintainability of an entity satisfies a specified requirement

Dido Solutions, Inc. and Jackrabbit Consulting, Inc., derived from the maintainability concepts in ISO/IEC 25010:2023

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.

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.
