Eliminates duplication: If technology is well managed, it will automate information flow in an organization. In this case, the technical team will set up a management information system (MIS) which provides periodic, predetermined and ad-hoc reporting capabilities. In most cases the MIS reports summarize or aggregate information to support decision-making tasks. So, MIS’s are systems that have information-processing responsibilities that include information through online analytical processing (OLAP) and conveying information to whoever needs it. To a small organization this process might be expensive, so people in charge must calculate return on investment. MIS’s are commonly known as ‘’management alerting systems ‘’’ because they send alerts to management concerned to the existence or potential existence of problems or opportunities.A management information system (MIS) provides reports in many different forms. Its reports can be periodic reports , summarized reports , exception reports , ad hoc reports and comparative reports.
