Most failures and successes are based on the business' operations....too much marketing/sales will drive a start-up to failure. Too much work setting up operations causes the business to really never start. My advice to my clients is if you are not a person who can balance both sides of business you need to get another person to take on the part you are not strong at...most of the time it is Operations....
