John, this is a really stimulating concept. The idea of only buying the software after the Scope/Proof is powerful: basically you do all the implementation and testing first, then put in the customer's keys on Go Live.
On new customers, how much showing of software do you do between the Vision Statement and getting their commitment to Scope? Do you often break the Scope step into several portions, increasing the $$ and the customer commitment with each?
On the Orphan side, what is the difference between the System Review and the Develop Scope/KTA?
