What Is The Difference Between Planning And Controlling?

While planning is looking ahead, controlling is acting in the pressent.  Planning and controlling are 'siamese sisters' and are inseparable as without one, the application of the other would be nothing but a practice in futility.

Any attempt to control without planning is as mentioned above totally futile when one does not even know whether he / she is going where they want to unless they know from the very beginning where they want to go.  Planning directs which way to go whereas controlling confirms whether it is the right way towards which one is heading and should be heading.  It also encumbers one's notorious tendency to get immensely affected by unwanted and gratuitous deviations that always become a purpose of distorting the objectives and planning process as well as the controlling mechanism.  Planning, thus, becomes the ultimate means to furnish and establish the particular benchmarks for developing an effective control mechanism.

Planning is a basic managerial function. It involves deciding on a course of action in advance. Planning is deciding what is to be done, where and how the work is to be done and who will do the particular task. We can say plan is to produce schemes for future action, to bring about specified results and specified cost, in a specified period of time. It is a deliberate, extent, speed and effects of change.  
Controlling is a procedure for measuring performance against objects. Controlling consist in verifying whether everything occurs in conformity with the plan adopted, the instructions issued and principles established. Its object is to point out weaknesses and error in order to rectify them and prevent recurrence. In short controlling facilitates the compliment of the plans. Although planning must preside controlling, plans are not self achieve. Plans guides manager in the use of the resources to the accomplished goal. Them activities are cheek to determine where confirm to plans. Some meaning of controlling like budget for expanse, in checking the record of labour hours lost. Each measure and each had shown where plans are working out. If devotion perishes, correct is innervated but what are correct activities through person.
