Minimum Viable Product (MVP)

The essence of the Minimum Viable Product (MVP) approach is that each product increment will attempt to deliver at least one outcome to at least a subset of the users of the system.
 --> Instead of shipping something we ship something of value.

Never delay feedback. Ever. Get really good at creating and evaluating the smallest increment possible to answer the question "Is our latest decision a good one?"
