Usability

Usability
Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, 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. Usability includes methods of measuring usability, such as needs analysis[1] and the study of the principles behind an object's perceived efficiency or elegance. Introduction[edit] The primary notion of usability is that an object designed with a generalized users' psychology and physiology in mind is, for example: In the user-centered design paradigm, the product is designed with its intended users in mind at all times.

Functional requirement In software engineering (and Systems Engineering), a functional requirement defines a function of a system or its component. A function is described as a set of inputs, the behavior, and outputs (see also software). Functional requirements may be calculations, technical details, data manipulation and processing and other specific functionality that define what a system is supposed to accomplish. Behavioral requirements describing all the cases where the system uses the functional requirements are captured in use cases. As defined in requirements engineering, functional requirements specify particular results of a system. In some cases a requirements analyst generates use cases after gathering and validating a set of functional requirements. Process[edit] A typical functional requirement will contain a unique name and number, a brief summary, and a rationale. The crux of the requirement is the description of the required behavior, which must be clear and readable. See also[edit] Roman, G.

Product requirements document A product requirements document (PRD) is a document written by a company that defines a product they are making, or the requirements for one or more new features for an existing product. A PRD is often created after a marketing requirements document (MRD) has been written and been given approval by management, and is usually written before (or at least concurrently with) a technical requirements document. It is designed to allow people within a company to understand what a product should do and how it should work. A PRD should generally define the problems that a product (or product feature) must solve, but should avoid defining the technical solution to those problems. A PRD sometimes serves as a marketing requirements document as well, particularly if the product is small or uncomplicated. Components[edit] Typical components of a software product requirements document are:[citation needed] Not all PRDs have all of these components. See also[edit] References[edit]
