Explain the purpose of an enterprise system

Enterprise systems integrate the functional systems such as accounting, finance, marketing, and operations. Another advantage of enterprise systems is that processes become more automated or totally automated, which increases efficiency. For example, by automating finance processes, a company can do things such as accept online orders and do business-to-business (B2B) transactions electronically, instead of via e-mail or offline methods such as telephone or fax.
Prior to selecting and implementing an ERP or other enterprise system, it’s essential that a company identify the problems to be solved, the goals to be achieved, and the type of support the information system is to provide.
