It looks dated. It breaks on a phone. Nobody can update it. Those are real problems, and they are usually what starts the conversation. But start there and the brief quietly becomes "make it newer" — and newness cannot be the goal. Whatever you choose for being new will be old again in three years.
Sites get rebuilt and the enquiries do not move. Most of the time, something that should have been kept was thrown out with everything else.
"Make it new" is the goal that strands you halfway
Set the purpose on the other side of the screen, not on your own. Who has to believe you, what they need to believe, and in what order. Write that as one line and most later decisions make themselves.
When the goal is newness, the test becomes whether something looks good — a test with a different answer for every person in the room. Opinions split, sign-off stalls, compromises stack up, and what ships is nobody's taste.
Name the person you want and you always have somewhere to return to. Would this photograph reassure them? Is this a word they actually use? Would they read this far in this order? Decisions get faster, and they hold even when the people making them change.
One line is enough. Long planning documents are re-read only by the person who wrote them.
