The Value Proposition Canvas zooms in on two of those building blocks, the Value Proposition and the Customer Segment, so you can describe them in more detail and analyze the “fit” between them. Companies need to get both right, the “fit” and the business model, if they don’t want to go out of business. The tools work best in combination. One does not replace the other.
