One of the beauties of the business model thinking is that we learn to see a business totally different if we really apply stringent thinking and dissect a business into its building blocks. And one of the most important concepts is that the value proposition is not the product.
The question what a good strategy is is difficult to answer. With hindsight it is easy: A good strategy is one that works. But in foresight? Many formulated, intended strategies are plain boring, generic and not customer centric, but focused on investors. Many business model innovators on the other hand have clear strategies that are focused on customers and on the value proposition.
