How do we keep our brand consistent across every team and touchpoint?

You say you manage the brand. What you actually manage is the gap between what you promise and what you deliver. That gap gets filled every day by people who never think about the brand at all — the support rep answering a ticket, the engineer naming a button, the salesperson making a joke mid-pitch. No strategy document closes that gap. It closes only when enough people, in enough small moments, choose the same thing without being told to. You cannot write your way to coherence. You can only decide, together, what you will do the next time it matters — and then do it, again and again. Most brand work flatters itself as creative work. It is not. It is the discipline of repeating a few true choices until they become habit. If your team is still arguing about brand values, you have not done the harder work yet: deciding who decides, and what happens the moment someone breaks the pattern.
