Abstract
This study evaluated the concept of using electronically delivered technical procedures to support maintenance operations in lieu of paper publications. The concept was tested on the basis of effectiveness, feasibility, and human factors issues. The Electronic Maintenance Publication System (EMPS) was tested on the PATRIOT system, an air defense missile system. No significant difference in maintenance time was found between EMPS or paper manuals. Errors committed while performing the tasks were negligible. Human factors issues were considered primarily to evaluate the concept of an electronic delivery and to guide refinement and future development of the system. Based on this study, it was concluded that an electronic delivery of maintenance information (as tested in EMPS) is an effective and feasible alternative to paper publications.
