Usability Inspection
Usability inspection is the name for a set of methods where an evaluator inspects a user interface. This is in contrast to usability testing where the usability of the interface is evaluated by testing it on real users. Usability inspections can generally be used early in the development process by evaluating prototypes or specifications for the system that can't be tested on users. Usability inspection methods are generally considered to be less costly to implement than testing on users. Usability inspection methods include: * Cognitive walkthrough (task-specific) * Pluralistic walkthrough * Heuristic evaluation (general) or (domain or culture-specific ) *Action Analysis * Guideline scoring or testing References {{reflist See also * Heuristic evaluation * Comparison of usability evaluation methods Usability testing methods aim to evaluate the ease of use of a software product by its users.

Usability Testing
Usability testing is a technique used in user-centered interaction design to evaluate a product by testing it on users. This can be seen as an irreplaceable usability practice, since it gives direct input on how real users use the system. It is more concerned with the design intuitiveness of the product and tested with users who have no prior exposure to it. Such testing is paramount to the success of an end product as a fully functioning application that creates confusion amongst its users will not last for long. This is in contrast with usability inspection methods where experts use different methods to evaluate a user interface without involving users. Usability testing focuses on measuring a human-made product's capacity to meet its intended purposes. Examples of products that commonly benefit from usability testing are food, consumer products, websites or web applications, computer interfaces, documents, and devices. Usability testing measures the usability, or ease of use, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Walkthrough
The cognitive walkthrough method is a usability inspection method used to identify usability issues in interactive systems, focusing on how easy it is for new users to accomplish tasks with the system. A cognitive walkthrough is task-specific, whereas heuristic evaluation takes a holistic view to catch problems not caught by this and other usability inspection methods. The method is rooted in the notion that users typically prefer to learn a system by using it to accomplish tasks, rather than, for example, studying a manual. The method is prized for its ability to generate results quickly with low cost, especially when compared to usability testing, as well as the ability to apply the method early in the design phases before coding even begins (which happens less often with usability testing). Introduction A cognitive walkthrough starts with a task analysis that specifies the sequence of steps or actions required by a user to accomplish a task, and the system responses to those acti ...

Pluralistic Walkthrough
The pluralistic walkthrough (also called a participatory design review, user-centered walkthrough, storyboarding, table-topping, or group walkthrough) is a usability inspection method used to identify usability issues in a piece of software or website in an effort to create a maximally usable human-computer interface. The method centers on recruiting a group of users, developers and usability professionals to step through a task scenario, discussing usability issues associated with dialog elements involved in the scenario steps. The group of experts used is asked to assume the role of typical users in the testing. The method is prized for its ability to be utilized at the earliest design stages, enabling the resolution of usability issues quickly and early in the design process. The method also allows for the detection of a greater number of usability problems to be found at one time due to the interaction of multiple types of participants (users, developers and usability profession ...

Heuristic Evaluation
A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface (UI) design. It specifically involves evaluators examining the interface and judging its compliance with recognized usability principles (the "heuristics"). These evaluation methods are now widely taught and practiced in the new media sector, where UIs are often designed in a short space of time on a budget that may restrict the amount of money available to provide for other types of interface testing. Introduction The main goal of heuristic evaluations is to identify any problems associated with the design of user interfaces. Usability consultants Rolf Molich and Jakob Nielsen developed this method on the basis of several years of experience in teaching and consulting about usability engineering. Heuristic evaluations are one of the most informal methodsNielsen, J., and Molich, R. (1990). Heuristic evaluation of user interfaces, Proc. ...

Guideline Scoring Or Testing
A guideline is a statement by which to determine a course of action. A guideline aims to streamline particular processes according to a set routine or sound practice. Guidelines may be issued by and used by any organization (governmental or private) to make the actions of its employees or divisions more predictable, and presumably of higher quality. A guideline is similar to a rule, but are legally less binding as justified deviations are possible. List of guidelines Examples of guidelines are: * Code of practice * EASE Guidelines for Authors and Translators of Scientific Articles * Federal Sentencing Guidelines * Guidelines for Examination in the European Patent Office * Medical guidelines * Publicly Available Specification * Programming style guidelines * UNGEGN Toponymic Guidelines The United Nations Group of Experts on Geographical Names (UNGEGN) is one of the nine expert groups of the United Nations Economic and Social Council (ECOSOC) and deals with the national and i ...

Comparison Of Usability Evaluation Methods
Usability testing methods aim to evaluate the ease of use of a software product by its users. As existing methods are subjective and open to interpretation, scholars have been studying the efficacy of each method and their adequacy to different subjects, comparing which one may be the most appropriate in fields like e-learning, e-commerce, or mobile applications.
