It’s the cornerstone of business: see a need, fill this need. The more you understand the needs of your customers, the more business you can get, because need determines demand and price, and right there is the crux of your enterprise. The only thing that matches a good need and being able to meet it, is being able to supply what people want irrespective of need. Not sure if this is true? Think about coffee, chocolate or even data. It is here that the line separating need and want becomes blurred; what is important is that we just got to have it.
