Business cannot exist on its own.  Like a musician without an instrument, unless there is something for the business to be active in, there is nothing, there is no music.  I can be a baker without having a shop but I cannot be a bread businessman without bread, the ability to get or make buns.  No matter how much I understand about the process, the pricing, mark-ups, turnover, promotion, innovation or roles within the organisation, without flour, oil, yeast and water, without getting stuck into baking, nobody will have anything to eat.
