A business plan deals with probability. It only focuses on the fact that things do not change from the current way of operations. Thus a business plan creates false certainty. All the plans and projects are based only on the managers or planners best guess as to the developments of the business. A business plan will of course neglect or tend to overlook at certain things like disasters and other unforeseen circumstances. This makes the business plan not wholly reliable and it might put the business into a risk of being unable to adapt to new threats and changes or even take advantage of new opportunities.
