One attempt at one task on one date, with constructed material: it is not a statement that the job, or this task in a given workplace, can be done by AI. The rubric, the attempt and the grade were made by the same model in one session, in that order; a person's check of a sample of grades will be published beside them.

The brief

You supervise the kitchen at the Harbor Street Conference Center. Saturday's event is a plated lunch for 120 guests at 12:30, three courses, with 8 vegetarian and 4 gluten-free guests. From the menu, the recipe yields, the staffing and the equipment below, write the production plan: portions and quantities per course, the production timeline worked backward from 12:30, station assignments and the layout of the plating line, and the plating sequence, with the holding temperatures that apply. Flag anything the numbers do not support.

The material

Constructed for this example; the names, figures and documents are invented.

MENU AND YIELDS
Course 1: tomato and basil soup, 8 oz portions, served hot and held at 165 F or above; one recipe yields 4 quarts (16 portions). A bread roll with it.
Course 2: roast chicken breast with lemon, one 6 oz breast per guest; a pan of 24 breasts roasts in 35 minutes at 400 F. Herbed potatoes, 5 oz portions; one hotel pan yields 40 portions, 45 minutes at 400 F; the standard seasoning contains flour, and a gluten-free seasoning is on hand. Green beans, 4 oz portions; a 5 lb bag yields 20 portions; blanch 4 minutes ahead, finish 3 minutes before plating. Vegetarian main: stuffed pepper, one recipe yields 12, bake 30 minutes at 375 F. Gluten-free guests: the chicken plate is gluten-free if the roll is omitted and the potatoes use the gluten-free seasoning; the soup is gluten-free.
Course 3: lemon tart, each tart cuts into 8 slices; a gluten-free tart (8 slices) from the pastry supplier is already ordered. Berries, 1 pint per 6 plates.

STAFF ON SATURDAY: you, two cooks (A and B), one prep cook (C), two dish and utility staff. Six servers, who do not work in the kitchen.

EQUIPMENT: two convection ovens, each holding 4 full hotel pans; a 6-burner range; one 10-gallon steam kettle; two hot holding cabinets, each holding 10 hotel pans; a walk-in cooler; a 12-foot plating line with a heat lamp over 6 feet of it.

SERVICE: each server carries 2 plates, so 12 plates leave per pass; the dining room is 60 seconds away. The client wants every main on the tables within 12 minutes of the first.

The rubric, written before the attempt

1. Quantities are right for every course. Evidence: Soup 30 quarts (7.5 recipes), which fits the 40-quart kettle in one batch; 116 rolls; 112 chicken breasts in 5 pans; 3 pans of potatoes with the gluten-free seasoning on at least the 4 gluten-free portions; 6 bags of green beans; one recipe of 12 stuffed peppers for 8 vegetarian plates; 15 regular tarts (116 slices) plus the gluten-free tart; 20 pints of berries.
2. Oven capacity is handled. Evidence: Nine pans (5 chicken, 3 potatoes, 1 peppers) against 8 slots, so the potatoes (45 minutes) and peppers are staggered against the chicken (35 minutes) with the holding cabinets in between, and the times are given.
3. A timed plan runs backward from 12:30. Evidence: Soup plating starting about ten minutes before service; the mains timed so that all 120 are on the tables within 12 minutes of the first; dessert after; every step with a clock time.
4. The service math is done. Evidence: 12 plates a pass and a one-minute walk, so 10 passes for 120 mains within 12 minutes means plates ready at about 10 a minute, and the line is staffed and sequenced for that, with who adds what to the plate in what order.
5. Stations, layout and holding are specified. Evidence: You, cooks A and B, prep cook C and the two utility staff assigned by course and task; the 12-foot line with the mains under the 6-foot heat lamp; soup and hot food held at 165 F or above; vegetarian and gluten-free plates kept apart and marked.
6. Flags where the numbers are tight, and nothing invented. Evidence: At least the oven slots, the holding time of the chicken, and the 6 feet of heat lamp for 120 plates; no equipment, staff or quantities beyond the material.

PRODUCTION PLAN, Saturday plated lunch, 120 covers at 12:30 (8 vegetarian, 4 gluten-free)

Quantities
- Course 1, soup: 120 x 8 oz = 960 oz = 30 quarts = 7.5 recipes, one batch in the 10-gallon (40-quart) kettle, held at 165 F or above. Rolls: 116 (no roll on the 4 gluten-free plates).
- Course 2, mains: chicken 112 breasts (120 less 8 vegetarian) = 5 pans of 24 (120 capacity, 8 spare). Potatoes 120 x 5 oz = 3 hotel pans of 40; one pan made with the gluten-free seasoning and used for the 4 gluten-free plates and extras, the other two with the standard seasoning. Green beans 120 x 4 oz = 480 oz = 30 lb = 6 bags. Stuffed peppers: one recipe of 12 for the 8 vegetarian plates (4 spare). Gluten-free plates: chicken, gluten-free-seasoned potatoes, beans, no roll.
- Course 3: 116 regular slices = 15 tarts (120 slices, 4 spare) plus the gluten-free tart (8 slices, 4 used). Berries 120 / 6 = 20 pints.

Oven plan (2 ovens x 4 pans = 8 slots; 9 pans to cook)
- 11:00 to 11:45: potatoes, 3 pans, oven 1 at 400 F. 11:15 to 11:45: stuffed peppers, oven 2 at 375 F; oven 2 is then raised to 400 F.
- 11:45: potatoes to holding cabinet 1 (165 F or above); peppers to holding cabinet 2.
- 11:50 to 12:25: chicken, 5 pans, 4 in oven 1 and 1 in oven 2, at 400 F. Out at 12:25 to holding cabinet 1.
- Green beans: blanched 4 minutes by 11:30 and chilled; finished 3 minutes on the range in two batches at 12:45 and 12:50.

Timeline backward from 12:30
- 10:30: soup started in the kettle (you); rolls counted; dessert plates to the walk-in.
- 11:00 to 12:25: ovens as above; cook A on potatoes and peppers, cook B on chicken.
- 11:30: beans blanched and chilled (prep cook C); soup temperature checked.
- 12:15: soup temperature checked; soup bowls staged; the line set.
- 12:18 to 12:30: soup plated at 10 bowls a minute (two ladling, one adding the roll); 12 bowls per server pass, 10 passes; course on the tables from 12:30.
- 12:45 and 12:50: beans finished on the range (C).
- 12:50: soup course clearing begins (utility staff).
- 12:55 to 13:07: mains plated at 10 plates a minute and carried 12 per pass, 10 passes, so the last main is down within 12 minutes of the first. Vegetarian (8) and gluten-free (4) plates are plated first on a marked tray at the end of the line and carried by one named server.
- 13:10 onward: dessert plated by prep cook C and one utility from cold plates; gluten-free slices on a marked plate.
- 13:30: dessert served.

Stations and layout
- Kettle: soup, you, with temperature checks at 11:30 and 12:15.
- Ovens and holding: cook A, potatoes and peppers; cook B, chicken. Both move to the line at 12:50.
- Range: prep cook C, beans at 12:45.
- Plating line, 12 feet, left to right: warm plate stack; potatoes (cook A); chicken (cook B); beans and lemon (prep cook C); check and wipe (you). The heat lamp covers the last 6 feet, where finished plates wait in rows of 12 so each server pass lifts a full set.
- Dish and utility: one on pots and the kettle, one running clean plates and the dessert plates from the walk-in; both clear the soup course from 12:50.
- Servers: 6, 2 plates each, 12 per pass, 60 seconds to the room.

Holding temperatures: soup at 165 F or above in the kettle; chicken, potatoes and peppers in the holding cabinets at 165 F or above until plated; beans finished to order; dessert on cold plates from the walk-in.

Flags
- Oven slots: nine pans against eight, so the potatoes and peppers cook first and hold about 70 minutes, which is long for potatoes. Alternative: 2 potato pans at 11:00 and the third with the chicken at 11:50 (5 chicken plus 1 potato uses 6 of the 8 slots).
- Chicken holding: out at 12:25, plated from 12:55, 30 minutes in the cabinet. Moving the chicken later risks the 12:55 start; this is the tightest point in the plan.
- Heat lamp: 6 feet of lamp holds about 24 plates, so the line must plate at the servers' pace of 12 plates a minute and not run ahead.
- Staffing: three on the line plus you is the minimum for 10 plates a minute; the utility staff are clearing soup at the same time, so if clearing falls behind, the soup bowls stay on the tables until the mains are down.

The grade

Graded 2026-10-01 03:54 UTC against the rubric above, by the same model.

Overall: passes. The plan does the arithmetic, respects the equipment and names the tight points. A chef may prefer the chicken out later than 12:25; the attempt says so itself.

How the examples are made and graded: the method. Every task of this job, with its length and when it comes within reach: First-Line Supervisors of Food Preparation and Serving Workers.
