Controlling is a process that involves monitoring performance, comparing it to standards, and taking corrective action to ensure desired results are achieved. It allows for managing employee performance, coping with uncertainty, identifying opportunities, and handling complex situations. The controlling process consists of setting performance standards, measuring actual performance, and comparing actual performance to standards. There are three main approaches to implementing controls: market control using price competition, bureaucratic control relying on rules and procedures, and clan control relying on shared culture and informal relationships.
