Planning leads to rigidity: In an organisation, a well-defined plan is drawn up with specific goals to be achieved within a specific time frame. These plans then decide the future course of action and managers may not be in a position to change it. This kind of rigidity in plans may create difficulty.

planning does not guarantee success :Managers have a tendency to rely on previously tried and tested successful plans. It is not always true that just because a plan has worked before it will work again.  

Planning reduces creativity: Planning is an activity which is done by the top management. Usually the rest of the members just implements these plans. As a consequence, middle management and other decision makers are neither allowed to deviate from plans nor are they permitted to act on their own.

planning does not work in a dynamic environment : It becomes difficult to accurately assess future trends in the environment if economic policies are modified or political conditions in the country are not stable or there is a natural calamity.
