Five critical success factors in UI/UX design standard

1) Gathering Information Designing is like making decisions. To make good decisions, you need the right information. The collection and analysis of information is called “user research”. If the information gathered is not good, the analysis will not be good. Information gathering methods: Good: Observation, think aloud and talk back Valid: Analytical, socio-demographic data, documentation Poor: workshops, focus groups and opinion polls 2) Who is the application for? Ease of use doesn’t mean anything. Those who will use the app once in their lifetime versus those who work 7 hours a day 5 days a week do not have the same definition of ease of use. For the first, the interface must be intuitive, for the second, speed and control ...

What is Cognitive engineering standard

Cognitive engineering combines system engineering and cognitive ergonomics. Ergonomics means the study of work. Cognitive ergonomics means studying mental work. Unlike design thinking where people are in the office trying to imagine human work and problems in committee, the cognitive engineer first makes a cognitive analysis of the task. Cognitive analysis of the task (Cognitive Task Analysis) is to observe one by one the users, ideally in the work environment, doing their work and asking them to think aloud. Observations are recorded and verbatim analyzed. The cognitive analysis includes the analysis of goals and subgoals, information consulted, knowledge, decisions and actions performed. The problems that are encountered and effective strategies are analyzed. Following the cognitive analysis of the task, ...

Why Card Sorting is Wrong standard

Card sorting is a technique that was originally used in libraries to organize large quantities of information. Card sorting uses physical cards with words (or pictures or physical objects). The cards are put on a big table and users are asked to group these cards into categories that make sense to them. This technique allows to understand how users group information but is a wrong approach to organize information in a user interface because: When users interact with computers, the optimal information organization is not necessarily logical. Information can be organized along: 1) frequency /importance of use; 2) sequence of task 3) logical group; 4) standards (ex: month of the years), 5) numerical or alphabetical order. When doing card ...
