Within systems engineering, quality attributes are realized non-functional requirements used to evaluate the performance of a system. These are sometimes named "ilities" after the suffix many of the words share. Notable quality attributes include:
- agility [Toll] (see Common Subsets below)
- autonomy [Erl]
- composability [Erl]
- discoverability [Erl]
- failure transparency
- interoperability [Erl]
- process capabilities
- reusability [Erl]
- serviceability (a.k.a. supportability)
- standards compliance
Many of these quality attributes can also be applied to data quality.
- Together, reliability, availability, serviceability, usability and installability, are referred to as RASUI.
- Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements.
- Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
- For databases reliability, availability, scalability and recoverability (RASR), is an important concept.
- Atomicity, consistency, isolation (sometimes integrity), durability (ACID) is a browser metric.
- When dealing with safety-critical systems, the acronym reliability, availability, maintainability and safety (RAMS) is frequently used.
- Dependability is an aggregate of availability, reliability, safety, integrity and maintainability.
- Integrity depends on security and survivability.
- Security is a composite of confidentiality, integrity and availability. Security and dependability are often treated together.
