Staffing function is considered to be the key to other functions of management. Do you agree?

Yes, staffing function is considered key to other functions of management because all other managerial functions depend on staffing. In fact, the effectiveness of other managerial functions depends on the effectiveness of the staffing function.
If an organisation employs right person, this will increase the work efficiency of an organisation. Thus, efficient staffing helps to improve the quality of planning, organising, directing and controlling.
