List of system quality attributes


List of system quality attributes

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
* accuracy
*
*
*
* agility
* auditability
* availability
* credibility
* standards compliance
* process capabilities
* compatibility
* composability
*
*
*
*
* dependability
*
*
*
* evolvability
* extensibility
* fidelity
* flexibility
*
* Integrity
* interchangeability
* interoperability
* learnability
* maintainability
* manageability
* mobility

* modularity
*
* operability
* portability
* precision
* predictability
*
* relevance
* reliability
* repeatability
* reproducibility
* responsiveness
* reusability
* robustness
* scalability
* seamlessness
* serviceability (a.k.a. supportability)
*
* simplicity
* stability
* survivability
* sustainability
*
* testability
*
* understandability
* usability


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

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.
