Steve Jobs was the CEO of the company he founded and during his tenure he presided over all of Apple's important events. But his being CEO is not why he gave Apple's presentations.
Steve Jobs didn’t run Apple’s keynotes because he was the company’s CEO; he ran them because he was the company’s best presenter.Exactly. Don't have the CEO do the presentations. Have the best presenter do the presentations. If that person happens to be the CEO, so be it.
And by the way, that advice is just as germane to every aspect of your organization. Don't assign tasks strictly by title. Assign them by merit.
