In the guide Canvases and templates
Business Model Generation has become a big reference. Explains – with loads of examples, use cases and nice illustrations – a simple and powerful tool to help entrepreneur shape their business ideas. It’s not a book to read but a book to consult as a reference.
On could say the knowledge in this book is also available for free on the web, in blogs, video etc… but the book is tangible and a good place to start.
