Think of a busy kitchen. The head chef owns the menu, the sous-chef makes sure every dish is perfect, and each cook runs their own station. Data governance needs the same clarity: who decides what data means, who looks after it day to day, and who answers when something goes wrong. Without that, even the best technology turns into a noisy, untrustworthy mess. This chapter maps out the people side of governance — the roles that turn rules into reality, the structures that give those roles power, and the practical ways to keep everything running when people wear many hats.
