\u201cextent 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<\/em><\/p>\n\n\n\n
Note 1 to entry: The \u2018specified\u2019 users, goals and context of use refer to the particular combination of users, goals and context of use for which usability is being considered.<\/em><\/p>\n\n\n\n Note 2 to entry: The word \u2018usability\u2019 is also used as a qualifier to refer to the design knowledge, competencies, activities and design attributes that contribute to usability, such as usability expertise, usability professional, usability engineering, usability method, usability evaluation, usability heuristic.\u201d<\/em><\/p>\n\n\n\n Usability is often also used interchangeably with ease-of-use, but according to its definition, it is about much more than that. It also deals with the overall satisfaction of the user. Usability also refers to methods for improving the ease of use during the design process.<\/p>\n\n\n\n \u201cUsability is about human behavior. It recognizes that humans are lazy, get emotional, are not interested in putting a lot of effort into, say, getting a credit card and generally prefer things that are easy to do vs. those that are hard to do.\u201d<\/em><\/p>\u2013 David McQuillen<\/em><\/cite><\/blockquote>\n\n\n\n <\/p>\n\n\n\n According to the ISO 9241-210<\/strong> standard, user experience is defined as Note 1 to entry: Users\u2019 perceptions and responses include the users\u2019 emotions, beliefs, preferences, perceptions, comfort, behaviours, and accomplishments that occur before, during and after use.<\/em><\/p>\n\n\n\n Note 2 to entry: User experience is a consequence of brand image, presentation, functionality, system performance, interactive behaviour, and assistive capabilities of a system, product or service. It also results from the user\u2019s internal and physical state resulting from prior experiences, attitudes, skills, abilities and personality; and from the context of use. <\/em><\/p>\n\n\n\n Note 3 to entry: The term \u2018user experience\u2019 can also be used to refer to competence or processes such as user experience professional, user experience design, user experience method, user experience evaluation, user experience research, user experience department. <\/em><\/p>\n\n\n\n Note 4 to entry: Human-centred design can only manage those aspects of user experience that result from designed aspects of the interactive system.\u201d<\/em><\/p>\n\n\n\n Because this may be hard to understand, Dan Norman and Jakob Nielsen, the inventors of the term User Experience, also have an easier explanation about what UX is about.<\/p>\n\n\n\n \u201cNo product is an island. A product is more than the product. It is a cohesive, integrated set of experiences. Think through all of the stages of a product or service \u2013 from initial intentions through final reflections, from first usage to help, service, and maintenance. Make them all work together seamlessly.\u201d<\/em><\/p>\u2013 Dan Norman<\/em><\/cite><\/blockquote>\n\n\n\n <\/p>\n\n\n\nUser Experience (UX)<\/h2>\n\n\n\n
