How important is a prototype for Andy Sycamore to succeed with his "Nested Learning?"

What will be an ideal response?

What Andy Sycamore is attempting to do with "Nested Learning" is to offer a better alternative to the typical paper and pencil-based training methods typically employed in most training sessions. This is an interactive, software-based tool where the answers are nested (one answer leads to a second question and so on — the nested part). As such, conceptually the idea may be difficult for trainers to understand. In short, it may be difficult for potential adopters to visualize the learning process embedded in Andy's idea. A prototype would be an attractive option here because using the prototype, Andy can actually demonstrate the efficacy of his process over conventional methods.
