Creativity is the generation and initial development of new, useful ideas. Innovation is the successful implementation of those ideas in an organization. Thus, no innovation is possible without the creative processes that mark the front end of the process: identifying important problems and opportunities, gathering relevant information, generating new ideas, and exploring the validity of those ideas.
That's the power of great insights. Insights, not ideas. There's a difference. Ideas, valuable though they may be, are a dime a dozen in business. Insight is much rarer -- and therefore more precious. In the advertising business, a good idea can inspire a great commercial. But a good insight can fuel a thousand ideas, a thousand commercials.
