List of System Quality Attributes
From Wikipedia, the free encyclopedia
Within systems engineering, quality attributes are 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:
- accessibility
- accountability
- adaptability
- administrability
- affordability
- agility
- auditability
- availability
- credibility
- compliant with standards
- composability
- configurability
- customizability
- degradability
- demonstrability
- dependability
- deployability
- distributability
- durability
- evolvability
- extensibility
- flexibility
- installability
- interchangeability
- interoperability
- learnability
- maintainability
- manageability
- mobility
- modularity
- nomadicity
- operability
- portability
- predictability
- recoverability
- relevance
- reliability
- repeatability
- reproducibility
- reusability
- scalability
- seamlessness
- serviceability (a.k.a. supportability)
- securability
- simplicity
- stability
- survivability
- sustainability
- tailorability
- testability
- timeliness
- understandability
- usability
Many of these quality attributes can also be applied to data quality.
[edit] Common subsets
- A subset of them (Reliability, Availability, Serviceability, Usability, and Installability) are together referred to as RASUI.
- Another subset used for Software Requirements (Functionality, Usability, Reliability, Performance, Supportability) are together referred to as FURPS.
- For databases RASR is an important concept (Reliability, Availability, Scalability, and Recoverability).
- When dealing with safety-critical systems, the acronym RAMS (Reliability, Availability, Maintainability and Safety) is frequently used.
