Operational business information systems tend to be used by lower level, non-managerial employees. The focus of operational BIS is on input or data collection. Operational information systems do process and output the data but the processing and output are very, very simple. For example, processing may simply be ordering the data collected. Output is usually just a list of all the data collected. Minimal calculations are performed or output. Often the output or dump of collected data by an operational information system is used as input into an information system with more sophisticated processing capability such as an MIS. Operational BIS include Transaction Processing Systems and Process Control Systems.
