When Apple (AAPL - Get Report) announced on Dec. 16 that Philip Schiller, the company's senior vice president of worldwide product marketing, would deliver the keynote speech at this week's Macworld conference instead of CEO Steve Jobs, speculation swirled again about the future of the company -- and Jobs's health.

Companies with strong corporate cultures can usually count on continued success if they can seamlessly transfer power to an executive from a strong bench of managers. But selecting Jobs's successor will be challenging, given the degree to which he is tied to Apple's identity. As Wharton management professor Michael Useem puts it: "There are few companies where the top person has as much of an impact
