A generic decentralized lean business model canvas was developed using the principles of business process management and lean six sigma for blockchain-based systems presented in this study. Based on the literature review, it was found that business model canvas and lean canvas are some of the most widely used management tools. Business Model Canvas can be used for selling a specific product and lean canvas can be used for solving a specific problem. Based on Business Model Canvas, a Decentralized Business Model canvas for decentralized space was developed in which the key parameters such as Problem definition, Key resources, Key activities, and learning were missing. As the Learn Parameter is missing, there is no mechanism for rectification of error/problems and it does not take into account the principles of Business Process Management and Lean Six Sigma. As many companies who have already implemented the principles of Business Process Management and Lean Six Sigma are now moving to establish blockchain in their business. Also, several startups use blockchain ideals in their business model. This motivated us to develop a novel decentralized lean business model canvas template. This can be made suitable for any blockchain-based use cases to make strategic management plans. It uses 13 key parameters and overcomes the limitations posed by other canvases. Validation of the decentralized lean business model canvas was done by considering a use case scenario for scholarly communication and scientific publishing. The proposed system competes on time, cost, quality, security, and trust.
