ABSTRACT
Technological innovations and a changing economic structure are forming a society in which knowledge dominates the core part of production capacity and requires workers to optimize their productivity (Nonaka and Takeuchi 1995). They are confronted with this requirement as it relates to work using knowledge. Therefore, in every business £eld, user support technologies are expected to aid and support the activities of workers. Support elements such as advisory, librarianship, reference, and training functions must suf£- ciently deal with the problems that workers face (Bramer and Winslow 1994). In the past, the functions of these elements were put together in the form of a manual. The electronic manual is an OJT (on the job training) oriented performance
model that combines increased business performance and business instruction/training (Haga and Kojima 1993; Kojima 1992; Yamada and Kojima 1997). It should essentially satisfy the requirements of high understanding of a task procedure, supplying knowledge and know-how at the task execution site, and acting as a task instructor and a task manager.
