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:

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.
