Control is the process of monitoring activities to ensure they are accomplished as planned and correcting deviations. An effective control system ensures activities lead to attaining organizational goals. Feedforward control prevents anticipated problems by taking action before issues occur, allowing management to prevent rather than cure problems. To reduce dysfunctionality of controls, management can increase flexibility and use multiple performance criteria. Planning and control are linked, as objectives set in planning are the standards used for control. Feedback is the most common type of control due to experience with it and difficulty establishing systems for feedforward.
