1. Little control on external factors: Generally no enterprise can control external factors such as government policies, technological changes, competitions etc.
2. Resistance from employees: Control is often resisted by employees. They see it as a restriction on their freedom e.g. Employees may resist and go against the use of cameras to observe them minutely.
3. Costly affair: Control is a costly affair as it involves a lot of expenditure of time and efforts.
4. Difficulty in setting quantitative standards: Control system looses some of its effectiveness, when standards cannot be defined in quantitative terms. In the absence of quantitative standards, comparison with standards becomes difficult.
