The Old Guard is the cultural bellwether of the company. I believe that culture is a slippery thing to fully define, but I do believe it is the responsibility of the Old Guard to not only take the time to define the key values that are the pillars of that culture, to communicate the nuance of those values over and over again, and, lastly, when it becomes apparent they are no longer serving the company, they must be willing to let those values evolve.
