A management information system (MIS) is a computer system consisting of hardware and software that serves as the backbone of an organization’s operations. An MIS gathers data from multiple online systems, analyzes the information, and reports data to aid in management decision-making.
The goal of an MIS is to be able to correlate multiple data points in order to strategize ways to improve operations. For example, being able to compare sales this month to sales a year ago by looking at staffing levels may point to ways to boost revenue. Or being able to compare marketing expenditures by geographic location and link them to sales can also improve decision-making. But the only way this level of analysis is possible is due to data that is compiled through an MIS.
