“The wise executive never looks upon organizational lines as being settled once and for all. He knows that a vital organization must keep growing and changing with the result that its structure must remain malleable. Get the best organization structure you can devise, but do not be afraid to change it for good reason: This seems to be the sound rule. On the other hand, beware of needless change, which will only result in upsetting and frustrating your employees until they become uncertain as to what their lines of authority actually are.”
