Guidelines checklist Invariably used in conjunction with a usability inspection method, guidelines and checklist help ensure that usability principles will be considered in a design. A heuristic evaluation is an evaluation method whereby a design is examined for instances in which certain heuristics or usability criteria are violated. It is similar to the cognitive walkthrough in that it is carried out by an expert but is less structured. Human factors Human factors is the field that studies the role of humans in man-machine systems and how systems can be designed to work well with people, particularly in regard to safety and efficiency. Information architecture The art and science of organising information to help people effectively fulfil their information needs.
Information architecture involves investigation, analysis, design and implementation.
The idea that design should be done in repeated cycles where, in each cycle, the design is elaborated, refined, and tested, and the results of testing at each cycle feed into the design focus of the next cycle. Interaction design Interaction design is a systematic and iterative process for designing highly interactive user interfaces. Methodology includes research and discovery techniques such as requirements analysis, stakeholder analysis, task analysis, as well as prototyping, inspection and evaluation methods. Likert scale A rating scale designed to measure user attitudes or reactions by quantifying subjective information. Participants indicate where along a continuum their attitude or reaction resides.
