Usability Module > Overview - 1 of 1


This module introduces the concepts of usability and user-centered design. Usability is a measure of how well a system supports operators and maintainers in task performance.  User-centered design is a methodology proven to result in high "usability."  It is characterized by designing all parts of the system to support the people who use it.  Also, called "human-centered" design, this approach focuses on the human role in the system.  Functions and tasks are allocated to the "human side" or "machine side," based on user capabilities and limitations.  "Machine-side" functions and tasks are allocated and designed to support human capabilities and compensate for human limitations.  User-centered design is an iterative process that seeks and incorporates feedback about usability throughout design, development, and test.
