Volume three of the IMIS Final Report documents the results and conclusions of each field test or demonstration conducted at Luke Air Force Base. Recommendations and lessons learned collected during the entire program (e.g., requirements analysis, system design, implementation, integration, test, installation, and demonstration) are provided. The IMIS project was an advanced development demonstration project which developed and field tested the technology to provide the maintenance technician with the capability to access all of the technical information (interactive electronic technical manuals, interactive diagnostics instructions, work orders, supply availability and ordering, historical data, training material, etc.) required to maintain aircraft via a single, integrated system, regardless of the source of that information. In the final phase of the project, an IMIS Demonstration System was developed and tested. In the field test, the performance of technicians on troubleshooting tasks when using the IMIS was compared with their performance on comparable tasks when using the paper technical orders. Test results indicated that technicians were able to perform the tasks significantly faster, used fewer parts, and made fewer serious errors when using the IMIS. In addition, the test indicated that, when using IMIS, non-specialist (crew chief) technicians could perform the tasks as effectively as the specialists.
