Quality Attribute

A Quality Attribute is a characteristic that expresses the degree of quality with which software satisfies requirements in addition to performing its functions. Examples include Security, Performance, Availability, Reliability, Resilience, Observability, and Maintainability.

SimpleModeling does not assign Quality Attributes to one particular model or modeling activity. They are cross-cutting design concerns examined against requirements, constraints, and realization methods identified in Object, Knowledge, Literate, Domain, and execution models.

Applications define their required quality levels and specific policies. Textus primarily provides runtime and operational mechanisms shared across applications. Design-time, AI-aware, and organizational or business qualities also depend on CML, Cozy, development conventions, component structure, technology selection, and operational policy.
