Originally conceived by Alexander Osterwalder, the Business Model Canvas is widely used by entrepreneurs to document the status of their business models. In principle, the Business Model Canvas can be used as a versatile tool for discovering and solving any type of pain on the planet. However, the Business Model Canvas is sub-optimally used. The Business Model Canvas has 12 "handicaps" that constrain it as a versatile tool for Open & Multilevel Pain Solving. This book critically and deeply explores the Business Model Canvas with a view to identifying as well as fixing its handicaps. Complementary tools such as the Business Model Strip, POKER Scorecard, and POKER Canvas are suggested to be used so that the full potential of the Business Model Canvas can be realized.
