An electronic performance support system (EPSS) is any computer software program or component that improves user performance. ''Electronic Performance Support Systems'' is also the name of a book, published in 1991, by Gloria Gery.〔http://www.amazon.com/Electronic-Performance-Support-System-Gloria/dp/0961796812〕 == Uses == Electronic performance support systems can help an organization to reduce the cost of training staff while increasing productivity and performance. It can empower employees to perform tasks with a minimum amount of external intervention or training. By using this type of system an employee, especially a new employee, will often not only be able to complete his or her work more quickly and accurately, but, as a secondary benefit, will also learn more about the job and the employer's business. An EPSS is best considered when workers require knowledge to achieve individual performance in a business environment. It is often furthermore considered when skilled performers are spending a lot of time helping less skilled performers; when new workers must begin to perform immediately and training is impractical, unavailable or constrained; or when employees need to be guided through a complex process or task that cannot be memorized. These situations often occur when new systems (e.g. customer relationship management, enterprise resource planning) are introduced, upgraded or consolidated, and in certain call centres when agents must perform using complex systems, processes or products. There are different views about the components and characteristics of EPSS. For example, from Barker and Banerji’s (1995) point of view, an EPSS has four functional levels, which should be brought together successfully. The first level is the user interface shell (the human computer interface) and the database; the second one is generic tools (help system, documentation, text retrieval system, intelligent agents, tutoring facility, simulation tools and communication resources); the third one is application-specific support tools; and the final level is a target application domain (schools, particular business settings, military, etc.). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「electronic performance support systems」の詳細全文を読む スポンサード リンク
