There's a lot involved in owning and managing a business. It is more so if you have the responsibility of staffing as well as the fulfillment to one's customers/clients. Rather than do a listing of what's required for business, perhaps a more blended approach would be more practical to those seeking to qualify themselves before entering the realm of business.
Though I can rattle off a list of characteristics necessary for the field of business, I get the feeling that a more detailed approach may be necessary to help the reader grasp what is really needed. In school, we get so caught up in passing exams and doing projects that like obtaining a driver's licence we only learn business when we get into it.
