Audit of the Department of Defense’s Implementation of Predictive Maintenance Strategies to Support Weapon System Sustainment (DODIG-2022-103)
Publicly Released: June 15, 2022
The objective of this audit was to determine whether the DoD tracked, monitored, and shared lessons learned regarding impacts of predictive maintenance on weapon system sustainment. Our objective was also to determine whether select predictive maintenance strategies achieved cost and availability goals. However, during the planning phase, we identified that the Services had not fully implemented predictive maintenance strategies. Therefore, we amended our objective to determine the extent that the DoD had implemented predictive maintenance in accordance with guidance.
