Business Model Design from ZERO is a tool designed for users to pattern a business model themselves based on basic patterns. The basic patterns are presented based on academic research. By modularizing it like Lego bricks, it can be understood module by module or designed in combination with each module. Establishing notation rules prevents miscommunication and facilitates comparisons, proposals, and evaluations among users. Possible to expand the scope of analysis and create a database. While expanding the base of users by setting general notation rules as a base, the scope of expression can also be expanded by adding minimal innovations to these rules. It can be used for the individual understanding of the business model as well as for group/organizational communication, such as teams/departments.
