A zen master asked a junior engineer to go get him a rock. The junior engineer asked what kind of rock he should get and the master replied by knocking him in the head with his cane. The junior thought for a minute, then asked, "would you like a round rock or a flat rock?" Again, the zen master rapped him on the head. The junior thought for a moment, then went to the creek and fetched a rock at random. He brought it to the zen master who inspected it and then said, "No, I want a flat piece of flint for starting a fire." The junior engineer was then enlightened.
Stakeholders will only give you requirements after they see the prototype. Thus, the spec and the prototype to elicit it are two sides to the same coin. Once the spec if correct and the prototype is starting to show its age, throw away the prototype and implement the spec with a fresh start.
