During some interactions with my local Innovation Center, I was introduced to the book Business Model Generation by Osterwalder & Pigneur. This book is full of useful information and powerful graphics and helps business owners and managers capture the essense of their business graphically using the “Business Model Canvas.”
The book goes on to describe various patterns of business models and providing several examples of business models used by some well-known and successful companies (e.g. Google).
I would highly recommend this book to any business owner. If you’d like to get a taste of what this book provides, here is a short PDF with the Canvas and some expcerpts from the book that explain how the Canvas works.
