Usability Engineering is a professional discipline that focuses on improving the usability of interactive systems. It draws on theories from computer science and psychology to define problems that occur during the use of such a system. Usability Engineering involves the testing of designs at various stages of the development process, with users or with usability experts. The history of usability engineering in this context dates back to the 1980s. In 1988, authors John Whiteside and John Bennett—of Digital Equipment Corporation and IBM, respectively—published material on the subject, isolating the early setting of goals, iterative evaluation, and prototyping as key activities. The usability expert Jakob Nielsen is a leader in the field of usability engineering. In his 1993 book Usability Engineering, Nielsen describes methods to use throughout a product development process—so designers can ensure they take into account the most important barriers to learnability, efficiency, memorability, error-free use, and subjective satisfaction before implementing the product. Nielsen’s work describes how to perform usability tests and how to use usability heuristics in the usability engineering lifecycle. Ensuring good usability via this process prevents problems in product adoption after release. Rather than focusing on finding solutions for usability problems—which is the focus of a UX or interaction designer—a usability engineer mainly concentrates on the research phase. In this sense, it is not strictly a design role, and many usability engineers have a background in computer science because of this. Despite this point, its connection to the design trade is absolutely crucial, not least as it delivers the framework by which designers can work so as to be sure that their products will connect properly with their target usership.
Content management (CM) is a set of processes and technologies that supports the collection, managing, and publishing of information in any form or medium. When stored and accessed via computers, this information may be more specifically referred to as digital content, or simply as content.
A technical writer is a professional information communicator whose task is to transfer information between two or more parties, through any medium that best facilitates the transfer and comprehension of the information. Technical writers research and create information through a variety of delivery media. Example types of information include online help, manuals, white papers, design specifications, project plans, and software test plans. With the rise of e-learning, technical writers are increasingly becoming involved with creating online training material.

Technical writing is the writing of technical content, particularly relating to industrial and other applied sciences, with an emphasis on occupational contexts. The range of audiences for technical writing varies widely. In some cases, it is directed to people with specialized knowledge, such as experts or technicians. In other situations, technical writers help convey complex scientific or niche subjects to end users who need a basic understanding of a concept rather than a full explanation of a subject. Technical writing is the largest part of technical communication.
The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types. It is an open standard that is defined and maintained by the OASIS DITA Technical Committee.
Task analysis is a fundamental tool of human factors engineering. It entails analyzing how a task is accomplished, including a detailed description of both manual and mental activities, task and element durations, task frequency, task allocation, task complexity, environmental conditions, necessary clothing and equipment, and any other unique factors involved in or required for one or more people to perform a given task.
Single-source publishing, also known as single-sourcing publishing, is a content management method which allows the same source content to be used across different forms of media and more than one time. The labor-intensive and expensive work of editing need only be carried out once, on only one document; that source document can then be stored in one place and reused. This reduces the potential for error, as corrections are only made one time in the source document.
JoAnn T. Hackos is a lecturer, consultant, and author of a number of books about technical communication. Now retired, Dr. Hackos is the founder of the Center for Information-Development Management (CIDM) and the president emeritus of Comtech Services in Denver, Colorado. She is also a fellow and past president of the Society for Technical Communication. She is a member of the IEEE Standards Association and active in the ISO SC7 Working Groups that is developing standards for information developers. She is the co-author of the standards on content management and information-development management.
In computing, a scenario is a narrative of foreseeable interactions of user roles and the technical system, which usually includes computer hardware and software.
In computing, minimalism refers to the application of minimalist philosophies and principles in the design and use of hardware and software. Minimalism, in this sense, means designing systems that use the least hardware and software resources possible.
Minimalism is a movement in visual arts, music, and other media that began in post–World War II Western art.
User experience design is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), which encompasses all aspects and stages of a customer's experience and interaction with a company.
John Millar Carroll is an American distinguished professor of Information Sciences and Technology at Pennsylvania State University, where he previously served as the Edward Frymoyer Chair of Information Sciences and Technology. Carroll is perhaps best known for his theory of Minimalism in computer instruction, training, and technical communication.
Structured writing is a form of technical writing that uses and creates structured documents.
SIGDOC is the Special Interest Group on Design of Communication of the Association for Computing Machinery (ACM), an international learned society for computing. ACM SIGDOC was founded in 1975 by Joseph "Joe" T. Rigo.
Technical documentation is a generic term for the classes of information created to describe the use, functionality or architecture of a product, system or service.
A component content management system (CCMS) is a content management system that manages content at a granular level (component) rather than at the document level. Each component represents a single topic, concept or asset.
