Even if you have a good business plan, your company can still fail, especially if you do not stick to the plan! Having strong leadership with focus on the plan is always a good strategy. Even when following the plan, if you had poor assumptions going into your projections, you can be caught with cash flow shortages and out of control budgets. Markets and the economy can also change. Without flexibility built in to your business plan, you may be unable to pivot to a new course as needed.
