Query: Great Book!

The book is clear, concise, and to the point. I used it as my standard reference in my training and for all my training delegates. This book gives you fantastic and powerful tools that you need to develop a business model. It does not show you how business models work from a finance stand, rather lets you combine this and that of tools to develop the model, based on your requirements. I like it very much. Good job!
