David C. Novak, former COO of Pepsi, talking about Pepsi Crystal in an interview with Fast Company:
It was a tremendous learning experience. I still think it's the best idea I ever had, and the worst executed. A lot of times as a leader you think, "They don't get it; they don't see my vision." People were saying we should stop and address some issues along the way, and they were right. It would have been nice if I'd made sure the product tasted good. Once you have a great idea and you blow it, you don't get a chance to resurrect it.
