InnoCentive has developed a service for client companies that outsources creative problem solving and innovations to outside problem solvers who might live anywhere in the world such as India, China, or Russia. What guidelines to follow for choosing the type of problems to be posted on the Internet would you suggest to a company that is going to use this service? What type of problems do you think would be preferable to solve internally (and not post on the Internet) using the company's own employees to develop a solution?
