I found the concept of the profit zone a very useful way to think about changes in business. I tend to think about companies in a very static way, as I’m analyzing them at one point in time (the current one). But the companies themselves are in a constant struggle to adapt to changing environments, and this book provides some terrific examples of a number of companies that have had to adapt their way into new business models as things have changed.
The only downside was that the writing style is a little dry, so at times it was a chore to get through.
I recommend the book to all interested in this topic.
