ISO 9241 - User Experience and Usability


Introduction of ISO 9241 serials standard

Measurements of a good product

ISO 9241 serials standards focus on ergonomics of human-system interaction, which is the measure of “good product” from the view of users of system, product and service. ISO 9241 serials standards supply a whole explanation, framework of ergonomics of human-system interaction and also an approach and guideline to create and manage ergonomics of human-system interaction.



of ISO 9241 serials standard

The key of ergonomics of human-system interaction following ISO 9241 is human-centered design (HCD), which refers to usability, accessibility, user experience and avoiding from harm of use, these four elements are called human centered quality (HCQ). ISO 9241 serials standards supply clear definitions, criteria and methodology for HCQ. Especially about usability ISO 9241-11 discusses in a unique document, because it is an important quality criteria of system, product and service. Even more ISO 9241-210 and -220 supply a manage module and framework for HCD, which is called human centered process (HCP), to introduce, assess and execute HCD in organization in different situations and for different purposes.

ISO 9241 serials standards improve not only the quality of system, product and service, but also the professional and manage ability of product and referred teams, even the effect and quality of manage in an organization.
