Who knows the most about a product? The creator or the user? Take, for example, surfboards. There is a whole population of surfers whose everyday focus is to maximize their experience in taking a wave. The best experience is found using the best board. Thus, the experts are the users. Von Hippel shows us that across many industries, information technology especially, users are the best minds to influence change and advancement. User innovation benefits all and in his manifesto, Von Hippel shows us why. This manifesto has been adapted from the first chapter of Democratizing Innovation.
