Small businesses need to think about creating or maintaining their vision. Many new companies start with a fairly well written vision statement. In the beginning, it is easy to harness the energy of the creation process and jot down the key points that are front-of-mind while the building is happening. But as time marches on, the original vision can become hazy. Perhaps through market change, economic slippage, employee turnover, or brutal competition, the original vision need some adjustment.
It is very important that the stakeholders review and reassess the vision. Make strategic or tactical adjustments as you must, but just do it.
