Strategic Planning should neither be rigid nor flexible. It shouldn’t be so rigid that there couldn’t be any changes made in the five to ten years of the plan. It also shouldn’t be that flexible those changes are made to the plan every month and the whole shape of the strategic planning changes. There can never be any correct amount of flexibility or rigidity for a plan. The flexibility depends on a variety of external and internal factors which includes social factors, environmental factors, and economical stability. The size of the product portfolio and the complexity of the organizations are also important in deciding how flexible a plan can be.
