This report identifies three critical problems in the life-cycle management of common shipboard equipment

• By 2014, depot maintenance accounted for nearly a third of the total operations and support cost of ships. A significant proportion of this work, which was unplanned, had to be done because the Navy had deferred maintenance of ships.
• The Navy's "troubled system" approach is inadequate because it cannot identify the reason why a system is troubled; it does not address the failures of low-cost equipment, even though the overall cost for repairing these failures is greater than for any others; and it does not account for every equipment failure.
• It is not possible to develop a complete picture of the systems driving maintenance costs without consulting multiple data sources, which at present are disconnected and incapable of producing a complete and accurate picture of the material state of ships in service.
