Prescriptive Maintenance (RxM)

The stage beyond prediction: systems that not only forecast a failure but recommend or initiate the specific corrective action.

Prescriptive maintenance closes the gap between knowing and doing. A predictive system says the bearing on pump P-14 will likely fail within three weeks; a prescriptive system adds the recommendation — replace the drive-end bearing, here is the procedure, parts are in stock at the central store, the optimal window is Thursday's planned line stop — and, at higher maturity, drafts the work order and reserves the parts itself.

The prerequisite is integration. Prescription requires the predictive signal, the work management system, the parts inventory, and the schedule to share one data fabric; a prediction in one system and a storeroom in another cannot compose a recommendation. This is why prescriptive capability tends to emerge on unified platforms and struggles on stitched architectures.

Human oversight remains part of the definition in serious deployments: prescriptions are recommendations with evidence attached, approved by planners, with autonomy extended action-class by action-class as track record accumulates. The technology pattern behind this is increasingly agentic — software that monitors, reasons, and acts within an explicit mandate.
