Jakub Simek from Pontis Foundation and Sote Hub created the fifth version of Effective Innovation Canvas to evaluate social innovation and business ideas.
Now this version is a radical departure and revision of the concept - the original inspiration from Business Model Canvas and Lean Canvas was replaced with the powerful idea of self-similarity or fractality (describing the project in ever granular detail and length in five levels with increasing numbers of sections: 0,1,2,4,8).
Again the inspiration comes from books like Exponential Organizations, Ten Types of Innovations, Antifragile, Zero to One. And concepts like Effective Altruism, Model Thinking, Theory of Change, Game Theory and Theory of Constrains and Systemic/Pattern Thinking.
