Abstract
While recent rapid changing business environment, the importance of business models has increased. From the viewpoint of program management, business models are designed in scheme model project, typically by using business model canvas and so forth. Even though CAD (Computer Aided Design) systems which support business model design are proposed, these features have been limited to support making consensus among stakeholders by assisting to sketch business models on computer screen. In this study, we discussed a concept of business model CAD system that provides advanced supports, based on business context mechanism library. We proposed a concept of business model CAD system, which provides the function to alert unexpected side-effects, not only to modeling and to simulate, with business context mechanism library. Moreover, we confirmed the feasibility of advanced supporting features through fictional scenarios where new business models are designed.
