The biggest mistake a small business or startup can make when considering what product or service to offer a market is to base that decision on some sort of 'gut feel' or to offer the market the story that YOU want to give or that you feel is servicing the market's need.
Much better to ask these 4 'why' questions:
1. Why would they want it?
2. Why would we offer it?
3. Why will they buy the next one?
4. Why will they recommend us?
