This paper presents the author's contention that a continuation of the current time-based failure data policies by all branches of the military forecloses prospects for substantial improvement in predictive maintenance and logistics. A concept is proposed for a stress-based data system that promises an affordable and precise prognostic capability for substantial improvements in combat readiness and logistics costs. The concept, geriometry, evolved during a DARPA-sponsored RAND study of the potential for the application of new technology in the maintenance of Army ground vehicles, in the late 1970s. A proof-of-principle experiment in one or more operating organizational units is necessary to reduce technical uncertainties, as a first step.
