The Business Model Canvas is a simple, living document that lets you capture all the important aspects of a business model on a single sheet of paper. But once you've created it, then what? You have to test your model. Use the business model canvas as a starting point for getting out into the real world and validating, verifying, confirming, or refuting the assumptions that went into building your model. Bit by bit, you build confidence in the model and reduce the risks inherent in your developing business. This presentation walks through the basics of identifying what parts of your model to test and how to think about constructing simple experiments against your canvas. This was given at the January 22, 2013 meeting of the Business Model Generation Meetup in Cambridge, MA. Please let us know what you think!
