The extent of potential savings depends heavily on your current situation—such as the maturity level of your maintenance organization, the proportion of reactive maintenance calls, the transparency of your cost structures, and the state of your spare parts management. Experience shows that a combination of process improvements, better management of outsourced services, and MRO optimization can achieve significant reductions in ongoing maintenance costs and inventory levels without compromising equipment availability. In addition, reliability engineering enhances equipment performance and increases availability. Specific target values are defined jointly as part of the health check and business case evaluation.
