Page 61 of the brand book I was handed last month contains a single sentence, bolded, with no explanation: the logo may never appear over a photograph of food. I asked four people why. Nobody knew. The person who did know left in 2019.
So I did what I always do, which is treat the document like a dig site. Two hours in the shared drive and I found it. A 2017 deck, a national account, a photo of a sandwich, and a senior vice president who hated it. The rule was not a principle. It was a peace treaty with a man who no longer works there.
Every brand book I have ever opened is at least half this.
The rules that came from craft and the rules that came from a bad Tuesday look identical on the page. Same typeface, same tone of authority, same implied threat. And because they look identical, a designer three years later treats a personality conflict as a law of physics.
Guidelines do not record what your brand believes, they record which arguments somebody was tired of having.
This is why brand books calcify. Nothing in the format captures reasoning, so nothing in the format can be revisited. A rule with a rationale can be tested against a new situation. A rule without one can only be obeyed or broken, and breaking it feels like insubordination, so people obey it into irrelevance.
The fix is not a rewrite. Rewrites just produce a fresh set of unexplained rules in a nicer grid. The fix is an inventory.
Go through the book line by line and sort every rule into three piles. One, rules that protect recognition: the logo lockup, the core color, the clear space. Those are real, they are why Liquid Death reads as Liquid Death on a shelf from ten feet away, and you leave them alone. Two, rules that encode a genuine point of view, the way Oatly's copy standards encode an attitude rather than a font size. Keep those and write down the why, in a sentence, in the book. Three, everything else. Fossils. Compromises. Settlements.
Guidelines do not record what your brand believes, they record which arguments somebody was tired of having.
For pile three, do not delete quietly. Delete with a note: removed, originated as a 2017 preference, no longer load bearing. That note is the most valuable page in the document, because it teaches the next strategist that rules have origins, which is the only thing that keeps the book from petrifying again.
I printed the audit and left it on the dining table overnight. Barnaby slept on pages 40 through 70, which is roughly the section I was proposing to cut. Truffles offered no opinion. Honestly, the strongest editorial feedback I got all week.
