Enterprise asset management is the business processes and enabling information systems that support management of an organisation's assets, both physical assets, called "tangible", and non-physical, "intangible" assets.
Physical asset management: the practice of managing the entire lifecycle (design, construction, commissioning, operating, maintaining, repairing, modifying, replacing and decommissioning/disposal) of physical and infrastructure assets such as structures, production and service plant, power, water and waste treatment facilities, distribution networks, transport systems, buildings and other physical assets. It is related to asset health management.
Infrastructure asset management expands on this theme in relation primarily to public sector, utilities, property and transport systems. Additionally, Asset Management can refer to shaping the future interfaces amongst the human, built, and natural environments through collaborative and evidence-based decision processes.
Fixed assets management: an accounting process that seeks to track fixed assets for the purposes of financial accounting.
IT asset management: the set of business practices that join financial, contractual and inventory functions to support life cycle management and strategic decision making for the IT environment. This is also one of the processes defined within IT service management.
Digital asset management: a form of electronic media content management that includes digital assets.
