ISO 9241-11:2018 is an international standard that provides a framework for understanding the concept of usability and applying it to situations where people use interactive systems, and other types of systems (including built environments), and products (including industrial and consumer products) and services (including technical and personal services).[^1^]
Usability is defined as "the extent to which a system, product or service can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use".[^2^]
The standard explains that usability is an outcome of use, defines key terms and concepts, identifies the fundamentals of usability, and explains the application of the concept of usability. It also describes the components of the context of use, such as users, goals, tasks, resources and environment. The standard does not describe specific processes or methods for taking account of usability in design development or evaluation.[^2^]
If you are interested in learning more about this standard and how it can help you design and evaluate systems, products and services that are usable for your intended users, you might want to download a PDF copy of it.
