For asset-intensive industries, any asset downtime can mean lost revenue. IBM Maximo® MRO Inventory Optimization and Support solutions help you optimize your maintenance, repair and operations inventory. Continuous optimization of MRO inventory can minimize downtime and costs. Using predictive and prescriptive analytics technology, MRO Inventory Optimization helps you cost-effectively maintain the ideal mix of critical MRO spares and materials to ensure the right spares are available at the right time, and at the right cost.

  • Up to 50% of unplanned asset downtime is due to stock outs, so having the right parts when needed is critical to your business.¹
  • Less than 20% of asset-intensive organizations have the right maintenance spares in stock at least 95% of the time.²
  • Up to 40% of maintenance workers' time losses can be attributed to spare parts inventory imbalance, so efficiency  leaks extend well beyond the storeroom.²


Reduce asset downtime by having the right maintenance repair parts in stock when you need them.

Keep MRO inventory optimized continuously to help reduce the cost of repair and replacement parts.

Improve internal service levels by maintaining an optimized MRO inventory to help cut unplanned downtime.
