Gartner defines the asset performance management (APM) software market as the software and applications that optimize the reliability and availability of industrial operational assets. The market is particularly attractive to asset-intensive industries, including power, utilities, manufacturing, oil and gas, natural resources, telcos, and transportation (excluding aviation, which has specialized requirements). In these industries, asset failure can have a significant impact on service delivery, the bottom-line revenue, and safety and reputation. APM is primarily deployed on industrial assets, including fixed industrial plants and equipment, linear assets or infrastructure, fleets, and facilities.
