How do I assess and validate my idea?

Under the hood here you’ll find a suite of practical tools to help you assess your ideas and concepts. These include: our Critique Pad for gathering feedback from others; our Idea Slide Rules for taking that feedback and translating it into a position in our impact-feasibility chart; and guidance for yourself or that you can share with others on how to critique and assess your own idea.
