What defines lost checks in the maintenance scheduling process?

The concept of lost checks in the maintenance scheduling process refers specifically to daily and situational checks that were planned but ultimately not accomplished. These checks are an essential part of routine maintenance as they ensure that all necessary inspections and operational tasks are completed to maintain the readiness and reliability of equipment and systems. When these checks are missed, it can lead to a breakdown in maintenance compliance and possibly result in safety risks or operational downtime.

In the context of the Navy 3-M System, lost checks highlight the importance of executing daily and situational checks as scheduled and the need for accurate tracking of maintenance activities. If these checks are not performed, it signals a failure in the maintenance process and calls for corrective actions to ensure they are addressed in the future.
