What does this mean? Quite simply... details matter. The seemingly insignificant details matter to the success of any endeavor. If you want to be successful you have to pay attention to the details.
Early in my coaching career I was a "big picture" guy. I didn't spend much time focusing on the how. I was more focused on the what. I didn't understand the value of coaching details. I thought we could out scheme people. If we drew it up on paper, we would win. That's what I thought it mean to out coach people.
Then I had the opportunity to watch Nick Saban coach defensive backs. He was focused on the how and the what. Coach Saban broke down small techniques to their smallest part. Everything fit together. If a player did something wrong, he immediately corrected them and they did it again. He had a process for teaching. Most importantly, his players learned and executed.
That is one common bond that successful teams shared... Attention to detail. They cared about the things that most organizations don't care about. They made it a point to take care of the small things. They set a standard, coached the standard, then held their players accountable to the standard. They accept nothing less. They focus on the details within themselves, rather than the external that they had no control over. While this wasn't the only factor they had in common, it was perhaps the most important.
