To convey fundamental concepts, it requires effort and time, both in short supply. But it's possible to conserve both by separating the fundamental concepts and intellectual skills from the content and particulars. That enables the training to focus on the essential fundamentals for effective performance. In such cases, traditional training approaches work well because they don't have to teach a lot of content. Regarding support tools, ones such as dictionaries were designed to recall elements of a job task and make memorization less necessary.
Technical manuals help workers access job-related information.
Those and other tools were developed to help workers accomplish tasks. With computers assisting job tasks, there's an opportunity to provide electronic performance support and positively reshape the training paradigm. The presentation of verbal information is crucial. Training should emphasize intellectual skills, when and how to access information, and not detailed data that is likely to change. For example, suppose workers need to focus on how to increase the amount of material shipped by a customer rather than on memorizing shipping codes.
