What Is Control?
Robert J. Mockler's definition of control points out the essential elements of the control process:
Management control is a systematic effort to set performance standards with planning objectives, to design information feedback systems, to compare actual performance with these predetermined standards, to determine whether there are any deviations and to measure their significance, and to take any action required to assure that all corporate resources are being used in the most effective and efficient way possible in achieving corporate objectives.
Types Of Control
Management can implement controls before an activity commences, while the activity is going on, or after the activity has been completed. The three respective types of control based on timing are feedforward, concurrent, and feedback.
