Killing things and performing tasks fills the bar. You'll see +150 or some other number pop up when the right things are done. That's filling your group's bar. When it is full, you fight the final boss. You keep doing the rooms until the bar is full. The better and faster you do each activity, the faster the bar fills and the faster you get to the final boss.

The timer is just a cutoff point for each activity. There are triumphs I think for finishing all before the timer runs out. The timer is there to keep your group from being stuck at one room for too long. There isn't any way to fail. You just take longer to finish filling the bar and fighting the end boss.
