Additional items are then obtained in anticipation of predicted or scheduled needs based upon management plans and schedules. Maintenance factors are used in determining the rates at which items must be provisioned.
The Depot Recoverability Factor (DRF) represents the difference between the number of times an item is inducted into the Depot Level for repair (unscheduled only) and the number of times those items were repaired and made Ready For Issue (RFI):
Example:

![]()
* Note: Beyond the Capability of Maintenance (BCM), Not Repairable This Station (NRTS). See Appendix C for definitions.
The rate that a consumable item will be replaced from its next higher assembly at the Organizational maintenance level is:
