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. Following a pre-decided plan, when circumstances have changed, may not turn out to be in the organisations interest.

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. Thus, much of the initiative or creativity inherent in them also gets lost or reduced. 

Planning is a time-consuming process: Sometimes plans to be drawn up take so much of time that there is not much time left for their implementation.

Planning may not work in dynamic environment: The business environment is dynamic, nothing is constant. The environment consists of a number of dimensions, economic, political, physical, legal and social dimensions. The organisation has to constantly adapt itself to changes.
