Assume absolutely nothing! Names may be misleading. Read the profiles and the objective of the exercise carefully!
It is a leadership reaction drill. Take charge if there is none, follow good ideas from others, put forth your good ideas, and know the difference between good and bad.
As mentioned earlier, it can actually be fun. Watch what you say, it may come back later, like in my case.
Good luck!
Inertia, inertia, inertia!!! Don't let it get you!
