What are the components of the 3-M system?

The 3-M system, as outlined in OPNAVINST 4790.1J, primarily focuses on the organized approach to maintenance management within the naval fleet. The core components of this system include planning, scheduling, and conducting maintenance, which are essential to ensuring that equipment and systems remain operationally ready and efficient.

Planning involves establishing strategies for maintenance activities, determining what needs to be maintained, and setting timelines for completion. Scheduling ensures that maintenance tasks are assigned and carried out in a timely manner, minimising disruption to operations. Conducting maintenance is the execution phase where actual hands-on work is performed to repair or maintain equipment.

By focusing on these three components, the 3-M system enables naval commands to effectively manage their maintenance workload, enhance accountability, and improve material readiness. This structure directly supports the overarching goals of operational effectiveness and mission success.
