My first sight of business model canva is the second picture. The tutor explained a lot at that time, but I still felt hard to understand the meaning and relationshio between each block. Untill I read the second picture in the book <Business model generation>.
The building blocks show different parts are relevently seperated. The shape which is an arrow expresses the active and passive relations between Value Propositions and Customer Segments. At same time, the illustrations on the arrows aid to express the communicability of themselves.
The illustration is good for concept communication. And the greatest advantage of table is easy to use. I believe that if the illustration was showed on that class, the whole class would feel easier to understand it.
