At every talk and workshop I try out something new to see if it sticks with the audience. An image that resonated a lot was describing the Business Model Canvas as a theater with a front stage and a backstage.

The Business Model Canvas is similar. The right-hand side of the Canvas is the front stage. The left-hand side of the Canvas is the backstage. Check out my little sketch outlining the front stage and back stage of the Business Model Theater:
