THE CONTROL FUNCTION OF MANAGEMENT Introduction The control function of management an organization is an activity to ensure that others are doing what should be done after strategy and organizational planning is made. The activities usually include a description of some type of measurement and feedback process. The basic process of controls involves three steps:- 1. establishing standards. 2. measuring performance against these standards. 3. correcting deviations from standards and plans

human operator. The main objective of a supervisory system is to give the means to the human operator to control and to command a highly automated process. So‚ the supervision of industrial processes includes a set of tasks aimed at controlling a process and supervising its operation. Supervisory control and data acquisition systems (SCADA) are widely used in industry for supervisory control and data acquisition of industrial processes. The process can be industrial‚ infrastructure or facility. SCADA
