Companies and non-profits can founder when CEO successions go badly–very often because a long-tenured CEO becomes an immovable object who ultimately only gives way to an irresistible force (such as death–J. Edgar Hoover; a board in revolt–ex-Disney head Michael Eisner; or a bureaucratic coup de grace–Admiral Hyman Rickover).  Disney seems to be getting it right this time, though the story refers to other companies that may be approaching an immovable object vs. irresistible force crossroads.
