Any strategy lives or dies on the basis of its customer value proposition. There are many typologies relevant to crafting a value proposition, because there are many ways to win customers. But the key issue is always: what is the center-of-gravity in our approach? Do we ultimately compete on the basis of our cost structure (e.g., Ryanair and Wal-Mart) or another basis that increases our target customer’s willingness-to-pay (e.g., Singapore Airlines and Nordstrom)? In other words, will we sell it for more or make it for less — and allocate sales resources accordingly?
