software quality assurance

software quality assurance (SQA) The process of ensuring that a software system and its associated documentation are in all respects of sufficient quality for their purpose. While a quality assurance team may be involved in all stages of a development project, there is typically a recognized quality assurance activity following completion of development and prior to release of the system for operational use.

The checks performed by the quality assurance team (which should be independent of the development team) vary between organizations and also depend on the nature and purpose of the software system. However they typically include functional testing of the software, checks that programming standards have been respected, that the program documentation is complete and of an adequate standard, and that the user documentation for the system is of the desired quality. The team would also probably explore the reliability of the software system, and attempt to ensure that the software system and its associated documentation are so organized as to promote system maintainability.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
