Alfred P. Sloan Quote

Manifestly, in any organization men should move from the bottom up to the top. That develops loyalty, ambition and talent, because there is a chance for promotion. Never inject a man into the top if it can be avoided. In a big organization to have to do that, I think, is a reflection on management. Of course there are always exceptional cases. As the years have passed, developing, as they naturally have, emergencies at times, I have been gratified to find that we have, with very few exceptions, been able to find right within ourselves some individual capable of assuming a greater responsibility, and he has always been given the opportunity.
