ERM also stands for enterprise relationship management.
1) ERM (enterprise resource management) describes software that lets an enterprise manage user access to its network resources efficiently. ERM software generally lets a user sign on to different enterprise systems and applications using the same password. ERM software makes it easy for the enterprise to control and keep track of which systems and resources each user has access to, and provides consistent standards for creating and changing passwords. One system administrator can usually manage user access to all platforms - UNIX, mainframe, Windows NT, and so forth - and to the applications on these platforms that require controlled access.
2) ERM (enterprise resource management) also describes software that manages all of a company's assets and resources, including such basic applications as general ledger, accounts payable and receivable, as well as manufacturing, inventory, and human resources.
