The correct answers are: Controlling, Co-ordinating, Commanding
Fayol wrote that to manage is to forecast and plan, to organise, to command, to co-ordinate and to control. Commanding is the exercise of centralised authority and leadership. Co-ordinating involves harmonising the activities of all groups towards the common objective. Controlling is measuring performance and accounting for deviations from plans. Writers after Fayol substituted functions such as motivating and consulting for commanding.
