Electronic Performance Support System (EPSS)
In 1989, AT&T debuts an Electronic Performance Support System, which coaches trainers on building tests.
Performance or Job Aids include technical manuals, decals, flowcharts, or other means of listing the steps for performing a task, while an EPSS is normally computer-based and may include wizards and Help Systems. Unlike a technical manual that must be printed, copied, and shipped to all the locations where it is used, an EPSS can be instantly updated.
EPSS can be thought of as software designed to improve worker productivity by supplying immediate on-the-job access to integrated information, learning opportunities and expert consultation, with the scope and the sequence controlled by the user.
