At Microsoft Partner Conference the MS CRM Team took the challenge of creating a xRM application in 24 hours. The team to fulfill this was Barry Givens, Nikhil Hasija, Reuben Krippner and Bryan Nelson.
To decide what kind of application to create they setup a vote on twitter where they ended up with 3 applications themes with the most votes. These where 1. a sports club management system, 2. a medical/healthcare system and 3. a golf course management system. The participants at the conference then voted again and the winner was the sports club management system.
And so the race began, and they actually did it. Nikhil Hasija is telling much more about it in the xRM Virtual User Group recording here.
The XRM Virtual User Group is a group for professional XRM Developers. They hosts virtual events from time to time with very interesting content.
