System management is the control of all corporate processes and business transactions
between suppliers, customers and employees. Systems management targets e-services in business transactions, but also individual customer needs, as in customer relationship
management (CRM), the control of operational business processes, asin enterprise resource
management(ERP), or the organizational and information technology control of logistics, as in supply chain
management (SCM). The systems management hierarchy takes into account the applications, middleware, operating systems, as well as networks, servers and their components.
A critical aspect is the integrity and continuous availability of business information. The IT resources that support a business process should be combined in a business system and managed centrally.
