Editing Usability engineering (section)

== International standards ==

Usability engineers sometimes work to shape an interface such that it adheres to accepted operational definitions of [[user requirements document]]ation. For example, the [[International Organization for Standardization]] approved definitions (see e.g., [[ISO 9241]] part 11) [[usability]] are held by some to be a context, efficiency, and satisfaction with which specific users should be able to perform tasks. Advocates of this approach engage in task analysis, then prototype interface design, and [[usability testing]] on those designs. On the basis of such tests, the technology is potentially redesigned if necessary.<ref>{{cite book|editor-last1=Coakes|editor-first1=Elayne|editor-last2=Willis|editor-first2=Dianne|editor-first3=Raymond|editor-last3= Lloyd-Jones|title=The new SocioTech : graffiti on the long wall|url=https://archive.org/details/newsociotechgraf00coak|url-access=limited|date=2000|publisher=Springer|location=London |isbn=1852330406|pages=[https://archive.org/details/newsociotechgraf00coak/page/n132 119]–125}}</ref>

The National Institute of Standards and Technology has collaborated with industry to develop the [https://www.nist.gov/publications/common-industry-specification-usability-requirements Common Industry Specification for Usability – Requirements], which serves as a guide for many industry professionals.{{Who|date=December 2014}} The [http://zing.ncsl.nist.gov/biousa/docs/Usability_and_Biometrics_final2.pdf specifications for successful usability in biometrics] were also developed by the NIST. Usability.gov, a no-longer maintained website formerly operated by the US [[General Services Administration]],<ref>General Services Administration, [https://www.usability.gov/ Usability.gov - Improving the user experience], accessed 5 November 2022</ref> provided a tutorial and wide general reference for the design of usable websites.

Usability, especially with the goal of [[Universal Usability]], encompasses the standards and guidelines of design for [[accessibility]]. The aim of these guidelines is to facilitate the use of a software application for people with disabilities. Some guidelines for web accessibility are:

#The Web Accessibility Initiative Guidelines.
#The Section 508 government guidelines applicable to all public-sector websites.
#The ADA Guidelines for accessibility of state and local government websites.
#The IBM Guidelines for accessibility of websites.
