Quality attributes

See list of system quality attributes

• accessibility: for people who experience disabilities.

• accountability: for answerability, annotatability, liability, and the expectation of account-giving.

• accuracy: for closeness of measurements to true values.

• adaptability

• administrability

• affordability

• agility

• auditability

• autonomy

• automatability for automation interactions with the system, components, tests, etc.

• atomicity: a transaction must be "all or nothing"; see ACID.

• availability

• compatibility

• composability

• configurability

• controllability: for controling the state of the system.

• consistency: the degree to which the system and its data must be consistent, such as changing only in allowed ways.

• correctness

• credibility

• customizability

• debugability

• degradability

• determinability

• demonstrability

• dependability

• deployability

• discoverability

• distributability

• durability: a transaction that is committed is preserved, even in the event of power loss, crashes, or errors; see ACID.

• effectiveness

• efficiency

• evolvability

• extensibility

• failure transparency

• fault-tolerance

• fidelity

• flexibility

• heterogeneity: uses diverse technologies, such as multiple languages and frameworks.

• homogeneity: uses the same technologies, such as one language and framework.

• inspectability

• installability

• integrity

• interchangeability

• interoperability

• instrumentability: the degree to which it is possible to instrument the system.

• isolateability: the degree to which items are kept separate, such as for ACID transactions, testing.

• learnability

• maintainability

• manageability

• mobility

• modifiability

• modularity

• monitorability: the degree to which it is possible to monitor the system.
