I was just in one where two of us were really the earners, and the other three were loafers.

In my current team, I have earned 75% of the total so far and the other four have combined for 25%.

The challenge, however, does mirror group projects in the classroom. THere is an interesting dynamic between the "leaders," the "followers" and the "credit-takers."

I think there is a part to learn about how to become a better team manager too, so maybe KA is trying to help students learn of this dynamic in a place that is not as "high-stakes" as the school.
