Part 1

It might be an exaggeration to say that it tells us nothing, but averages don’t usually give us enough information to be useful.

Individual student level: In Math class, kid gets an ‘A’ on his test on positive and negative integers. Then he gets a ‘C’ on fractions. Score averages to a ‘B’… but when the kid moves on to algebra, and most of the algebra includes solving problems with fractions, it’s unlikely the kid will do better than a ‘C’. The important information is the ‘C’ in fractions, not the ‘B’ average.

On a team level: When some team members have done amazing things and other tram members have done nothing new, measuring the average means absolutely nothing. You can’t look at averages when some team members will move and some won’t. The reality is that everybody has to be moving in the right direction, and when some are standing still, it doesn’t matter where the average is, it doesn’t matter if the average is moving slightly up.

The fact is that we are failing or we have failed if we don’t figure out where we are weakest and improve where we need it most. Athletes get this. They know that the weakest part of their performance is the area where there is the most room for improvement… this is a mindset we need on our teams to move forward.
