Though they offer different messages, idea entrepreneurs have plenty in common. Quite a few of them have published books with the word “innovation” in the title. All of them hate to be called consultants. “I like to position myself as a thought leader,” says Vijay Govindarajan, a professor at Dartmouth’s Tuck School of Business and co-author of “The Other Side of Innovation.” “A consultant solves problems,” Govindarajan says. “That is not my role. What I want is for companies to self-diagnose their problems and self-discover their own solutions through my thought leadership.”
