We rehearsed the hand-over twice to ensure that the presentation will go smoothly. Dry runs are very important when a distributed team is making an important presentation.
Effort : It took us an hour of preparation for every minute of the presentation. For example the 30 minute demo took about 30 hours to design, build and rehearse. The overview took about 5 hours to design build and rehearse. The sales and marketing section of the presentation part took about 4 hours of planning, creation, discussion and rehearsal.
