Chapter 10 — Discussion Guide

1. "You do not buy ingredients for dishes. You buy deliveries and decide what they become." Is that a genuine reframe or a rhetorical one? What to listen for: students should be able to name what actually changes operationally under the reframe — the order guide is written from the map rather than the menu, par levels are set on programs rather than dishes, and the first question about a proposed item becomes "what else does this reach?" Strong answers notice that the reframe also changes who writes the menu: if purchasing is the input, the person placing the orders has to be in the room, which is not how most menus get written. Push toward the failure mode: a restaurant that adopts the language without changing the documents has adopted nothing.

2. Bellwether cut raw oysters, a fried item, risotto, and duck breast. Which of the four would you fight hardest to put back, and what would you give up for it? What to listen for: the trade is the point. Every restoration costs something specific — the fryer costs hood capacity out of a construction budget that is already thin (Chapter 6), risotto costs a body on the line at peak, oysters cost a health-department risk category and a refrigerated display, duck costs a delivery line feeding one dish. Students who argue for an item without naming the payment have not done the exercise. The best answers notice that duck is the cheapest to restore operationally and the hardest to justify strategically, which is an interesting inversion.

3. The chapter says the golden triangle "is not established" rather than "is wrong," and then recommends the placement anyway. Is that intellectually honest or is it having it both ways? What to listen for: run this one carefully; it is the chapter's most important discussion and the one most likely to go shallow. The defensible position is that the action and the justification are separable: you may take an action whose cost is zero and whose upside is uncertain, provided you do not claim evidence you do not have. Push with the follow-up that separates good answers: "What would you have to believe for this to be dishonest?" — and the answer is, if it cost something, or if you told a lender it would lift sales 12%. Then generalize: how many practices in any professional field are conventions with no evidence and no cost? Is that a problem?

4. A cost lever with a demand side must be measured on both. Case Study 2's operator kept 17% of a \$96,629 improvement. What went wrong, and at what point was it fixable? What to listen for: students initially blame the chef, which is wrong and worth correcting — the rebuild was excellent work. The failure was in measurement scope: prime cost improved and was measured; the guest experience degraded and was not. Push them to name a measurement available in month three: covers by returning guest, the composition of two-item checks, review language, the placement rate computed at design time. Then ask the harder question — is there any restaurant report that would have caught it? — and let them sit with the answer, which is essentially no. That is why the judgment matters.

5. The chapter puts \$6.45 of non-ingredient cost on a plate that sells nine a week. Should a restaurant remove every item that fails that test? What to listen for: the correct answer is no, and articulating why is the exercise. Reasons to keep a low-volume item: it serves an occasion or a dietary need nothing else serves; it is the reason a specific segment comes at all; it is a component of the brand's claim about itself; or its sales are genuinely incremental rather than transferred. Push on incrementality specifically — it is the question almost nobody asks and Chapter 28 will make them ask it again about delivery. Watch for students who treat the \$6.45 as a decision rule rather than as an input; that is the same error as treating food cost percentage as a decision rule, and Chapter 1 already warned about it.

6. Bellwether's peak fire utilization is 68%. Is that a good number or a frightening one? What to listen for: both, and the argument is about risk appetite rather than arithmetic. Sixty-eight percent means the line works and has about a third in reserve; it also means one over-performing item, one large party ordering four ribeyes, or one cook having a bad ten minutes eats a large share of that reserve. Ask what utilization they would design to, and why. Then ask the question that reframes it: "What is the cost of designing to 50% instead?" — which is a smaller menu, fewer hearth items, or a bigger fire, and every one of those has a price. Connect to Chapter 1: in a four-cent-margin business, reserve capacity is expensive and its absence is fatal, which is exactly the shape of every hard decision in this book.

7. Chapter 2 fixed \$33.12 of food per cover before anybody had written a menu. Was that the right order, or should the menu have come first and the check average followed from it? What to listen for: the strongest closing discussion in the chapter, and there is a real argument on both sides. For the plan's order: the check average is constrained by the trade area and the competitive set, which are facts about the world, and a menu that produces a check the market will not pay is a fantasy however good it is. Against: a check average derived from occasion assumptions is itself a guess, and building a menu to hit a guessed number can produce a menu nobody wanted. The resolution most students reach — that the two must iterate, and that what matters is writing down which one you fixed — is the right one. Push them to say what they would do if the honest menu came out at \$29 of food per cover instead of \$33.12: raise prices, change the item mix, cut costs elsewhere, or revise the revenue forecast? Every one of those is a real option and three of them change other sections of the plan.
