Slicing the Cake - User story slicing

Cake consists of several layers, similar to software system that consists of several architectural layers. Think of a whole story as a multi-layer cake, e.g., a network layer, a persistence layer, a logic layer, and a presentation layer. When we split a story, we're serving up only part of that cake. We want to give the customer the essence of the whole cake, and the best way is to slice vertically through the layers. ~ Bill Wake
