Management control is an important managerial function that helps check for errors and take corrective actions to minimize deviations from standards and achieve organizational goals. Control involves setting performance standards, measuring actual performance, and taking corrective action if needed. There are three main types of controls: feedforward controls prevent deviations, concurrent controls monitor ongoing work, and feedback controls review past performance against standards. The control process involves establishing standards, measuring performance, comparing to standards, and taking corrective actions.
