Just tell me exactly what you want

Life would be so much simpler if our customer would just tell us exactly what they want the product to do. I wonder why they don’t just write it all down, then we can go off and build it?

The manifesto starts by saying: We are uncovering better ways of developing software by doing it and helping others do it. It’s important to understand that it says uncovering – it doesn’t claim to be the definitive How To for software development. Sixteen years later, I think it’s safe to say we are still uncovering better ways.
