There's an expression in business that "a better mousetrap might not be enough." It's intended to convey the idea that a better product or service isn't always the most successful (or even successful at all) in the marketplace.

For example, McDonald's has been the most financially successful purveyor of hamburgers in the world yetI think most people would agree--doesn't make the most delicious, highest-quality ones available.

If we accept that premise, how do you believe conducting a market analysis and customer segmentation helps to overcome the "not better enough" mousetrap problem?
