The Demo — The Jerry McGuire Moment!
'Show me the money!' That's right... base milestones on an objective evaluation of working systems.... show it... demo it... show and tell ... that's where the money is...and the feedback...don't forget the feedback. Feedback on what has been shown goes both ways between the team and the customer. This allows the team to adapt according to the customer feedback ... and for the customer to adapt according to the work presented.
