Spares management and optimisation is increasingly recognised as a foundation of cost-effective operating processes. Operations will be more susceptible to prolonged downtime events if critical spares are not properly managed. While proper MRO management stand to save considerable inventory costs.

PRISM can assist to catalogue spares by item in a Bill of Material (BOM) and Prioritizing spares based on importance. Ability to spot trends in how assets consume critical spares may indicate a need for realigned maintenance plans
