"The talent myth assumes that people make organizations smart. More often than not, it's the other way around."
- Malcolm Gladwell, What the Dog Saw, The Talent Myth
Great systems make people look good.
You see this in sports all the time. When playing in the right system, otherwise ordinary players look good, and good players look great. Take those players out of the system and put them on a dysfunctional team and their performance drops substantially.
Talent is important of course, but 'blue chip' recruits aren't enough. You have to have great systems to support them and maximize their potential.
So as a leader you need to ask yourself, "What am I doing to create better systems that can make those who operate inside of them shine?"
