Management information systems (MIS) jobs focus on the information technology used by managers to understand employee and business performance. You develop and maintain an MIS system, determine when to add new technology or services and coordinate with IT personnel to ensure the company has everything it needs to monitor its performance. Many MIS employees also help create reports, program new features, and create guidelines for using and maintaining the system. Security and redundancy are important in this role, so MIS employees often create backup systems and limit outside access to the system. MIS should not be confused with Medical Information Systems, which fulfill a similar role in the healthcare industry. Be sure to review job postings carefully if they use MIS in the name because it could refer to either of these terms.
