You have an idea for a company that sources fruits from local farms and makes fresh juices on a daily basis. You want to start a subscription-based service in which households within a 100-mile radius subscribe to your plan and receive two gallons of freshly squeezed juice (for example, cherry juice, apple juice, lemonade) twice a week. As you think about starting your business, you ask yourself: Am I being responsive to the customer? Is it innovative? Can I offer a quality product? After asking these questions, review and identify which question you forgot to ask that would give you a sustainable advantage.
