Planning and controlling are two separate fuctions of management, yet they are closely related. The scope of activities if both are overlapping to each other. Without the basis of planning, controlling activities becomes baseless and without controlling, planning becomes a meaningless exercise.

In absense of controlling, no purpose can be served by. Therefore, planning and controlling reinforce each other. According to Billy Goetz, “Relationship between the two can be summarized in the following points”

1. Planning preceeds controlling and controlling succeeds planning.
2. Planning and controlling are inseperable functions of management.
3. Activities are put on rails by planning and they are kept at right place through controlling.
4. The process of planning and controlling works on Systems Approach which is as follows :
   Planning    →    Results    →    Corrective Action
5. Planning and controlling are integral parts of an organization as both are important for smooth running of an enterprise.
6. Planning and controlling reinforce each other. Each drives the other function of management.

In the present dynamic environment which affects the organization, the strong relationship between the two is very critical and important. In the present day environment, it is quite likely that planning fails due to some unforeseen events. There controlling comes to the rescue. Once controlling is done effectively, it give us stimulus to make better plans. Therfore, planning and controlling are inseperate functions of a business enterprise.
