I think there are some things that cause business to fail: 1. business runs are not in accordance with the expertise owned, so he can not run a good business, 2 too focused on product development, so forget the marketing process. This will lead to product marketing constrained, and ultimately lost by other competitors, 3. do not want to innovate in product development and marketing. This will lead to less compete in marketing, 4. not able to manage financial management well.
