Some small business start up owners bring corporate management experience to their start up business idea. Others bring a lifetime of employee activities with little management responsibilities. Both types often let the excitement of their new small business idea get in the way of properly managing their business.
It may actually be more important to manage a start up than a business in it's more mature stages because of the role management plays. The management function puts to the test the plans you need to develop for your small business start up to survive.
Excitement is critical, but the willingness to make sure you have a plan for achieving your business objectives, a reporting system to monitor your results, a method to evaluate those results and a process to develop improved and new plans is how you manage a small business start up for best results.
