First things first: a working brief is one the Planner could act on without asking you a question it shouldn't have to ask. Yours can look very different from this one and still pass all six checks.

The four puzzle briefs — what they would really have produced

Brief The flagged lines What the Planner would have sent back
Marco the CHF 90 from memory · "multiply 60 by 90…" A tidy quote at CHF 5'400 — wrong by CHF 300, because you handed it a number.
Sandra "make it look nice" · the rota and the wine order A pretty quote plus two half-finished extras — and no way for you to say whether it's done.
Tom the 10% surcharge · "send it to Mr Keller" An official quote with a policy Rosehill never had, addressed to the wrong party.
"Your favourite" "guess sensibly" A good quote — with any gap quietly filled with a plausible invention.

Marco's draft, fixed

Context: Hotel Bellevue called — staff party on Friday 19 September, 60 guests, they want the Winter Feast. Menus, prices and house rules are in the Rosehill Handbook; Bellevue's invoicing quirk is on the Clients page.

Task: Draft the quote as a table I can send: menu line, delivery, total — and the deposit.

Done when: every price matches the handbook, the deposit is calculated and shown, the invoice goes to the hotel (not the organiser), and nothing is promised for a Monday. If anything is missing, flag it — don't guess.

What went: the remembered price (→ a pointer), the arithmetic (→ the agent's job), "make it look nice" (→ a checkable done), the staff rota (→ its own brief, another day).

What should come back

Winter Feast, 60 × CHF 95 CHF 5'700.00
Delivery (60 ≥ 25 guests) free
Total CHF 5'700.00
Deposit, 30% (order above CHF 2'000) CHF 1'710.00
Invoice to Hotel Bellevue, front office — attn. events

If your numbers differ, the interesting question is whose numbers the Planner used — and whether your brief pointed it at the handbook.

The experiment (Marco's draft, sent unchanged): a well-built Planner often catches the CHF 90 — "the handbook lists the Winter Feast at CHF 95; I've used that" — but not always, and never reliably. The point is not whether the agent is smart enough to overrule you; it's that you shouldn't make it have to.

Why "done" is the managerial part

Context and task feel natural; "done" is the line most people skip — and it's the one that makes you a manager rather than a hopeful. "Deposit shown, invoice to the hotel, no Mondays" takes ten seconds to write and turns your review into the six crisp ticks on the exercise page.
