The first principle of the Agile Manifesto is about "valuable software". Value is subjective; it's the perceived benefit we get from something. Imagine you are working for an It department in a large organization. You want to deliver valuable software with iterative delivery. There might be dozens of stakeholders with dozens of definition of value. How do you ensure you are both "building the right thing" and "building the thing right"? Suppose you are increasing your productivity, you might be building the wrong product faster. This book describes how a large organization uses techniques to focus on the right product and to deeply anchor the idea that less output can deliver more outcomes.
