The purpose of control is not only to detect errors and defects in performance of work, but also to adopt remedial measures. Without taking corrective actions, control has no meaning. The base of controlling process is taking actions in order to ensure that the actual activities conform to the planned activities. For example, if actual output falls short of standard output, we take several actions like checking the raw material, checking the production activities, corrective actions may be taken, analysis of standards, reassignment of duties, bringing change in the style of production, etc.
