Usability WikipediaUsable redirects here. For the idea contest, see USable. Many tools are designed to be easy to hold and use for their intended purpose. For example, a screwdriver typically has a handle with rounded edges and a grippable surface, to make it easier for the user to hold the handle and twist it to drive a screw. Usability is the ease of use and learnability of a human made object such as a tool or device. In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.

The object of use can be a software application, website, book, tool, machine, process, vehicle, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects such as a cookbook, a document or online help and mechanical objects such as a door handle or a hammer.

Monthly programs available, call todayUsability includes methods of measuring usability, such as needs analysis3 and the study of the principles behind an objects perceived efficiency or elegance. In human computer interaction and computer science, usability studies the elegance and clarity with which the interaction with a computer program or a web site web usability is designed. Usability differs from user satisfaction and user experience because usability does not directly consider usefulness or utility. IntroductioneditThe primary notion of usability is that an object designed with a generalized users psychology and physiology in mind is, for example More efficient to usetakes less time to accomplish a particular task. Easier to learnoperation can be learned by observing the object. More satisfying to use. Complex computer systems find their way into everyday life, and at the same time the market is saturated with competing brands. Windows 8 vs. Windows 7 comparison in terms of speed and performance. Windows 8 has a faster performance but is slower for 3D and high res gaming. This has made usability more popular and widely recognized in recent years, as companies see the benefits of researching and developing their products with user oriented methods instead of technology oriented methods. By understanding and researching the interaction between product and user, the usability expert can also provide insight that is unattainable by traditional company oriented market research. For example, after observing and interviewing users, the usability expert may identify needed functionality or design flaws that were not anticipated. A method called contextual inquiry does this in the naturally occurring context of the users own environment.

Acceptance testing Formal testing conducted to enable a user, customer, or other authorized entity to determine whether to accept a system or component. Information regarding the development, coordination, and implementation of statewide testing programs in California. Usability testing is a technique used in usercentered interaction design to evaluate a product by testing it on users. This can be seen as an irreplaceable usability. Why Is Gilgamesh A Hero Essay. In the user centered designparadigm, the product is designed with its intended users in mind at all times. In the user driven or participatory design paradigm, some of the users become actual or de facto members of the design team. The term user friendly is often used as a synonym for usable, though it may also refer to accessibility. Usability describes the quality of user experience across websites, software, products, and environments. There is no consensus about the relation of the terms ergonomics or human factors and usability. Wwe Raw Full Game Setup Free Download on this page. Some think of usability as the software specialization of the larger topic of ergonomics. Usability Testing Programs' title='Usability Testing Programs' />Others view these topics as tangential, with ergonomics focusing on physiological matters e. Usability is also important in website development web usability. According to Jakob Nielsen, Studies of user behavior on the Web find a low tolerance for difficult designs or slow sites. People dont want to wait. And they dont want to learn how to use a home page. Theres no such thing as a training class or a manual for a Web site. People have to be able to grasp the functioning of the site immediately after scanning the home pagefor a few seconds at most. Otherwise, most casual users simply leave the site and browse or shop elsewhere. DefinitioneditISO defines usability as The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. The word usability also refers to methods for improving ease of use during the design process. Usability consultant Jakob Nielsen and computer science professor Ben Shneiderman have written separately about a framework of system acceptability, where usability is a part of usefulness and is composed of 7Learnability How easy is it for users to accomplish basic tasks the first time they encounter the design Efficiency Once users have learned the design, how quickly can they perform tasks Memorability When users return to the design after a period of not using it, how easily can they re establish proficiency Errors How many errors do users make, how severe are these errors, and how easily can they recover from the errorsSatisfaction How pleasant is it to use the design Usability is often associated with the functionalities of the product cf. ISO definition, below, in addition to being solely a characteristic of the user interface cf. For example, in the context of mainstream consumer products, an automobile lacking a reverse gear could be considered unusable according to the former view, and lacking in utility according to the latter view. When evaluating user interfaces for usability, the definition can be as simple as the perception of a target user of the effectiveness fit for purpose and efficiency work or time required to use of the Interfacecitation needed. Each component may be measured subjectively against criteria, e. Principles of User Interface Design, to provide a metric, often expressed as a percentage. It is important to distinguish between usability testing and usability engineering. Usability testing is the measurement of ease of use of a product or piece of software. In contrast, usability engineering UE is the research and design process that ensures a product with good usability. Usability is a non functional requirement. As with other non functional requirements, usability cannot be directly measured but must be quantified by means of indirect measures or attributes such as, for example, the number of reported problems with ease of use of a system. Intuitive interfaceseditThe term intuitive is often listed as a desirable trait in usable interfaces, often used as a synonym for learnable. Some experts such as Jef Raskin have discouraged using this term in user interface design, claiming that easy to use interfaces are often easy because of the users exposure to previous similar systems, thus the term familiar should be preferred. As an example Two vertical lines on media player buttons do not intuitively mean pausethey do so by convention. Aiming for intuitive interfaces based on reusing existing skills with interaction systems could lead designers to discard a better design solution only because it would require a novel approach. This position is sometimes illustrated with the remark that The only intuitive interface is the nipple everything else is learned. Bruce Tognazzini even denies the existence of intuitive interfaces, since such interfaces must be able to intuit, i. Instead, he advocates the term intuitable, i. He continues, however, But even that is a less than useful goal since only 2. ISO standardseditISOTR 1. ISOTR 1. 69. 82 2.
