Great designers design, that's why they're so great.
You will group with others to design solution to presented problem.
NO INTERNET, NO COMPUTERS, just pen and pencil... and your ideas.
No hire/fire power over other team members.
No time to check it all, so use ASSUMPTIONS.
After design, you will have to present your solution to others and answer their questions... as well as those from the client.
Don't worry, you get to ask others too. ;-)
