List Of System Quality Attributes

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. They are usually Architecturally Significant Requirements that require architects' attention.[1]

Quality attributes

Notable quality attributes include:

Many of these quality attributes can also be applied to data quality.

Common subsets

  • 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 transaction 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.
