Execution is the job of the business leader.
Complexity has nothing to do with intelligence, simplicity does.
Execution is a systematic process of rigorously discussing hows and whats, tenaciously following through, and ensuring accountability.
If you don't have the best people you hurt everyone.
How people talk to each other absolutely determines how well the organization will function.
I saw that leaders placed too much emphasis on what some call high level strategy, on intellectualizing and philosophizing, and not enough on implementation. People would agree on a project or initiative, and then nothing would come of it.
