In Why Startups Fail, Tom Eisenmann introduces the Diamond-and-Square (DaS) framework. Like the Business Model Canvas (BMC), the DaS represents the value proposition, the marketing activities that drive customer acquisition and retention, and the technology and operations (resources and activities) that all translate into the revenues and costs that feed a profit formula.
Unlike the point-in-time perspective of the BMC, the DaS reflects the necessity for the startup to gain the resources necessary and apply those resources successfully to achieve a sustainable profit formula. The DaS and the BMC are complementary. Entrepreneurs should be thankful to have the Diamond-and-Square framework to add to their toolbox in building and scaling a successful startup.
