(i)'Planning may not work in a 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. 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.
(ii) 'Planning does not guarantee success': The success of an enterprise is possible only when plans are properly drawn up and implemented. Any plan needs to be translated into action or it becomes meaningless. 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.
