Book excerpt: Analyses were made to compare job performance aids (JPAs) and technical orders (TOs) in terms of the process by which they are developed, their contents, and their production costs. Throughout the comparisons, some attention was given to the functions that each type of technical data best supports. In comparison to TOs, JPAs are developed by a more rigid process which starts with systematic descriptions of maintenance tasks and personnel. In content, JPAs normally have many more illustrations, more blank space and a simple standard format for rather detailed directions. Currently available cost data do not support any substantive conclusions about the initial and long term relative costs of TOs and JPAs for a given system. Additional pertinent conclusions were: (1) Any technical data system used by maintenance men must include an illustrated Parts Breakdown, (2) Providing both JPAs and TOs to a given maintenance technician would not be optimal, (3) Technical data should be developed according to a systematic procedure which includes task analysis and a description of the users, (4) Future technical data should be adaptable to various modes of presentation, (5) Unambiguous guidance for the performance of troubleshooting tasks is highly desirable, (6) Illustrations and standardized language increase the utility of technical data for maintenance.
