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 ...

The Cognitive Approach standard

Introduction IT projects tend to be executed in distinct phases. 1. determining the business needs, 2. setting system specifications for those needs, 3. programming and then 4. testing. The first two phases usually represent 50%[1] of a project’s cost. The traditional way of determining the business needs is to ask users or subject matter experts to express the needs verbally. Analysts then transcribe them and define the system requirements that will meet the needs. System requirement’s documents are finally reviewed and approved.

Change Management : A Catch-22 standard

The catch-22 The levels at which impacts of change are major are not understood while the levels at which impacts are minor are easily understood. Why? Most managers believe people resist change because humans have a natural desire to keep the status quo. They believe that resistance to change is a defense mechanism caused by frustration and anxiety. With this diagnostic, executives belief that good change leadership comes with a strong message from the top, effective communication plan, mandatory training and sometimes, removing undesirable parties that are labeled as strong change resistant.

10 Things to pay attention in evaluating user interface standard

it would be wrong to rate user interface solely, and compliance to set of heuristic since the impact of each one of them depend of the context of use. For example, it is wrong to say that the CNN web complies at 75% while the New York Times web site complies at 88%. Prior to applying heuristics, it is essential to have a good grasp of the user profile and task. User Profile comprises a description of the user frequency of use (once in a lifetime or everyday), familiarity with technology, gender age, and training, etc. The task description comprises: what are the user Goal, Sub goal and Methods and Frequency (looking for flight arrival 95% of the time, booking a flight 5% of the time) Get three to five independent evaluators that share the list of heuristics, user profile and task. Each one of them evaluate the user interface during one or two hours separately Share the findings together and rate each problems in term of high medium and low impact. High impact problems prevent user from performing their tasks while low impact might be an aesthetic aspect or a nice-to-have feature.

What user want! standard

I expect the system to provide me all  information I need without being overload. I want to be able to accomplish my task in the natural flown of my thinking without being distracted. I don’t want to have to perform unnecessary steps, actions, calculation, or take notes. I want to be able to read and understand, symbols an graphic instantly. I expect have feedback following my actions. I want interaction techniques to be consistent and familiar. I expect the system prevent errors or provide errors recovery mechanism. I want the system provide rapid method for frequent task and guidance for unfamiliar task. I want visibility. I don’t feel uncomfortable with hidden processes. I want to find my way easily.
