Although the innovation process is messy and non-linear, every innovation we studied went through similar steps. If you are starting with a problem, work through the steps. If you already have a technology or product, go back to understand the problem you are solving. Avoid using surveys and market studies — really go deep and understand the hearts and minds of your customers during the process. Although you won’t eliminate the risk of innovation, you can dramatically reduce it and dramatically reduce the cost of failure, giving you multiple chances to launch a home run.
