According to Weihrich and Koontz; “All managers, from presidents to first-level supervisors – plan.”Plans should not only be effective, but also efficient.

So planning will also define all the future functions of management.
We have already been introduced to five essential managerial functions, namely, planning, organizing, staffing, leading and controlling.
