An event like the CCDC is not possible without the support and assistance of many people who volunteer their time and energy for the benefit of the cause. The yellow and white teams were an essential part of the event, and their efforts were noticed. In short, the yellow team was responsible for the evaluation and grading of the teams' business injects. They were made up of the team representatives that helped to organize and train the students.
The white team consisted of a wide range of individuals who were responsible for designing the event, managing it while underway, and keeping everything flowing. These people were responsible for keeping the core network up and running, and for keeping track of the overall progress of the various teams. This group was so busy that after watching them for a few hours, I had to take a break!
