There are ten people in a room and there is one window in this room. Everyone prefers the window in a configuration and at least one person most prefers the window completely closed and at least one person most prefers the window completely opened. Without knowing the preference of others, come up with a process to determine the state the window should be kept in based on everyone's preference. Test your process by assigning everyone preferences and seeing if your process works and if you are happy with the outcome.
