Does computer-based training impact maintenance costs and actions? An empirical analysis of the US Navy’s AN/SQQ-89(v) sonar system

The United States Navy decided in the early 2000s to replace traditional, instructor-led schoolhouse training with computer-based training (CBT). While employing CBT may produce gains in knowledge acquisition and lower costs for repetitive, low-skill work, there is a lack of empirical evidence whether these benefits exist for more highly skilled Navy operations. Anecdotal evidence suggests that CBT failed to sufficiently prepare new sailors for sophisticated systems’ maintenance and operation. To determine the validity of this evidence, we examine how CBT has affected the AN/SQQ-89(v) sonar. We empirically analyse whether the Navy’s introduction of CBT significantly altered fleet maintenance costs, actions and training requirements, by assembling a unique data set of ships, locations, personnel, maintenance costs and maintenance actions. Controlling for the Navy’s plan to man the system, the number of authorized billets and the number of personnel on board, we find that CBT adversely impacts costs, actions and maintenance hours for the sonar system.
