This chapter is about the art of saying “no” (or “not yet”) so you can focus on what truly matters. Pinning down what’s in scope (and what isn’t) early can save everyone a world of pain. Projects often drown in wish-lists and shifting requirements, but you can prevent that chaos from the start. Bring clarity with simple tools like scope lists and negotiate changes without losing your cool. We also tackle prioritization: identify the highest-value work and happily delay or cut the rest. Sometimes doing less is the best way to succeed!
