OK, this seems to have taken forever but understand one of the dynamics of building world-class products and services - you must go slow early to go fast later.

In Show 4 we covered the key questions to start build the prototype. Let's take that a little deeper.

Topics:

• What Is The Design?
• ​Build a model of the initial process
• How Are You Going to Test It?
• ​Do a walk through, imagine what happens at each step and record the initial brainstorm
• What Must You Learn to Build It Right?
• ​Based on the walk through and brainstorming - make 3 lists: based on facts, where are you certain (no assumptions); based on a few assumptions - where do you have reasonably certain; what don't you know

This is list is where the Design Phase and the Development meet.
