The Usability Engineering Lifecycle By Deborah Mayhew Pdf

Several broad disciplines including Psychology, Human Factors and Cognitive Science subsume usability engineering, but the theoretical foundations of the field come from more specific domains: human perception and action; human cognition; behavioral research methodologies; and, to a lesser extent, quantitative and statistical analysis techniques.

When usability engineering began to emerge as a distinct area of professional practice in the mid to late 1980s, many usability engineers had a background in Computer Science or in a sub-field of Psychology such as Perception, Cognition or Human Factors. Today, these academic areas still serve as springboards for the professional practitioner of usability engineering, but Cognitive Science departments and academic programs in Human-Computer Interaction now also produce their share of practitioners in the field.[citation needed]

In usability engineering, it's important target and identify human errors when interacting with the product of interest because if a user is expected to engage with a product, interface, or service in some way, the very introduction of a human in that engagement increases the potential of encountering human error. Error should be reduced as much as possible in order to avoid frustration or injury. There are two main types of human errors which are categorized as slips and mistakes. Slips are a very common kind of error involving automatic behaviors (i.e. typos, hitting the wrong menu item). When we experience slips, we have the correct goal in mind, but execute the wrong action.Mistakes on the other hand involve conscious deliberation that result in the incorrect conclusion. When we experience mistakes, we have the wrong goal in mind and thereby execute the wrong action.[4]

Some well-known practitioners in the field are Donald Norman, Jakob Nielsen, Deborah Mayhew and John M. Carroll. Nielsen and Carroll have both written books on the subject of usability engineering. Nielsen's book is aptly titled Usability Engineering, and was published in 1993. Carroll wrote Making Use: Scenario-Based Design of Human-Computer Interactions in 2000, and co-authored "Usability Engineering: Scenario-Based Development of Human-Computer Interaction" with Mary Beth Rossen in 2001. Some other field leaders are Alan Cooper, Larry Constantine and Steve Krug the author of "Don't Make Me Think! A Common Sense Approach to Web Usability". 2ff7e9595c
