I’m watching a lot of football this time of year, and all of these teams are filled with star athletes, even at third-string. Yet only some teams are far above the pack. it’s not the athletes, it’s the coaching.
The same applies to business. Watch any company rise from the ashes (IBM) or descend into chaos (GE) and the employees haven’t significantly changed, leadership has.
You don’t need a great consultant to explain this to you or to boards of directors, but one just did.
