Navy maintenance is becoming increasingly difficult with more complicated systems, reduced staffing, and efforts to reduce expensive training time. To improve maintenance readiness, the Navy is testing tablets by which technicians receive performance aids and directly connect with the larger Navy maintenance enterprise system. Technicians' performance can be improved by (1) micro controlled experiments which investigate interface details of accessing and presenting content via tablets and (2) macro field tests that illustrate the effect of technological tools in their deployed state. A comprehensive approach to improve productivity and decrease cost through tools is best informed by both micro and macro studies, and to integrate the results of both to create and promote Navy goals. The micro element of our approach is the study of how a tablet-based presentation of procedures can be structured to provide technicians the support needed to maximize performance. We will report results from one such study, identifying difficulties introduced by tablets and how they can be overcome, and the capabilities now possible with interactive tablets. The macro element of our comprehensive approach is the study of how the Navy maintenance technicians can benefit when connected to enterprise resources. Technician benefits include an ability to order components when technicians are in the field, access updated technical documentation, and automatically collect work performance data which reduces redundant paperwork and enables big-data analytics to identify interesting trends of previously unknown efficiencies and performance difficulties. We will report results from a recent field test that includes lessons learned from connecting technicians to the enterprise system. Micro studies provide scientific verification of principles used to develop the solution, and macro studies reveal how well the solution improves work flow and productivity in the Navy context.
