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.
