Why Production Planning Matters

A professional bakery is not just about great recipes — it is about getting the right products finished at the right time, every time. On any given morning, a bakery may need baguettes, dinner rolls, whole-wheat sandwich loaves, and focaccia all ready before doors open. If you start mixing in the wrong order, you run out of oven space, products proof too long, or items finish cold. Production planning prevents those failures before they happen.

This lesson teaches you to build a backward production schedule, scale formulas accurately using baker's percentage, and document quality through a formal quality control (QC) audit.

Building a Backward Production Schedule

Backward scheduling means you start with the finish time — say, 7:00 a.m. opening — and work backward through every step to find the latest safe start time for each product.

For each item, list every stage and its typical duration:

Once you have durations for each stage, subtract backward from the finish time to find when mixing must begin. Write every step on a timeline sheet so the full production is visible at once.

After drafting the schedule, check for equipment conflicts: two products cannot occupy the same deck or rack oven at the same time unless you have confirmed the oven holds both pans. Identify conflicts on paper and adjust start times or batch order before you ever touch flour.

Scaling Formulas with Baker's Percentage

Baker's percentage expresses every ingredient as a percentage of the total flour weight. Flour is always 100%. If a formula uses 500 g flour and 350 g water, water is 70%.

To scale up or down:

1. Determine the desired total dough weight (unit weight × unit count, plus a small overage for scaling loss).

2. Add all formula percentages to find the total percentage (flour % + water % + salt % + yeast % + any other ingredients %).

3. Divide the desired dough weight by the total percentage (expressed as a decimal) to find the new flour weight.

4. Multiply the new flour weight by each ingredient's percentage to find its scaled weight.

Always have a second person or the instructor verify your math before you measure any ingredient. An arithmetic error in a large batch wastes significant product and cost.

Digital scale safety: Place the scale on a stable, level surface. Zero (tare) the scale before each ingredient. Never exceed the scale's rated capacity, and keep it away from water sources to protect electronics.

Sequencing Multiple Products

When running several doughs simultaneously, the general rule is: longest process first. Whole-wheat sandwich loaves typically have longer fermentation than baguettes; start them earliest. Focaccia may need a long pan proof at room temperature; plan that pan space too.

Batch your oven loads so products bake in sequence without gaps. If two products need the same oven temperature, bake them together. If temperatures conflict, schedule them in separate loads and adjust start times accordingly.

Quality Control Audit

Quality control (QC) is the systematic process of measuring finished products against a defined standard and recording any gap. In a licensed commercial bakery, QC records support food safety compliance and help identify recurring problems. For ACF and RBA credentials, understanding QC principles demonstrates professional competence.

For each product, your audit should include:

Write your findings on the QC report template. Be specific and honest — a QC report that ignores problems is useless.

Safety in a Production Environment

Mixer safety: Keep hands and utensils away from moving dough hooks or paddles. Use the bowl guard when provided. Turn the mixer off and wait for it to come to a complete stop before scraping the bowl.

Oven safety: Use heavy oven mitts or gloves rated for high heat. Call out "behind" or "hot" when moving through a busy kitchen with hot pans. Set hot sheet pans on designated surfaces, never on edges where they can fall.

Cutting safety: Keep bench knives and lame blades pointed away from the body during scoring. Score with a controlled, deliberate motion. Dispose of razor-style blades in a puncture-resistant sharps container.

Lifting: Commercial batches can be heavy. Bend at the knees, keep the load close to your body, and ask for help with anything over a safe personal limit. Never twist at the waist while carrying a heavy bowl.

Sanitation: Wash hands before production begins and after any break. Sanitize work surfaces between dough types to prevent cross-contamination, especially when working with whole-grain or seeded products alongside plain doughs.

Key terms8

Baker's percentageA formula notation system in which every ingredient is expressed as a percentage of the total flour weight; flour is always 100%, allowing easy scaling up or down.
Backward schedulingA planning method that starts from the required finish time and subtracts each process step's duration to determine the latest acceptable start time for each task.
Bulk fermentationThe first rise of a yeast dough after mixing, during which yeast activity and enzymatic reactions develop flavor and structure before the dough is divided and shaped.
Final proofThe last fermentation period after shaping, during which the dough expands to its baking volume before entering the oven.
Equipment conflictA scheduling situation in which two or more products are planned to use the same piece of equipment — such as a deck oven or proofer — at the same time, making simultaneous production impossible.
Quality control (QC) auditA structured evaluation of finished products against established standards, documenting measurements such as weight, crust color, and crumb structure, and identifying corrective actions for any deviations.
Corrective actionA specific, actionable change made to a process or formula to bring a product back into conformance with its quality standard after a deviation is identified.
TareThe function on a digital scale that zeros out the weight of a container so only the net weight of the ingredient being measured is displayed.

Worked examples4

1. A base baguette formula uses 500 g flour, 350 g water, 10 g salt, and 4 g instant yeast. You need to produce baguettes with a total scaled dough weight of 2,400 g. Find the new weight of each ingredient.
  1. Step 1 — Calculate baker's percentages from the base formula. Flour = 100%. Water = (350 ÷ 500) × 100 = 70%. Salt = (10 ÷ 500) × 100 = 2%. Yeast = (4 ÷ 500) × 100 = 0.8%.
  2. Step 2 — Add all percentages to find the total percentage: 100 + 70 + 2 + 0.8 = 172.8%.
  3. Step 3 — Convert total percentage to a decimal: 172.8 ÷ 100 = 1.728.
  4. Step 4 — Divide desired dough weight by that decimal to find the new flour weight: 2,400 ÷ 1.728 = 1,388.9 g (round to 1,389 g).
  5. Step 5 — Multiply the new flour weight by each ingredient's percentage (as a decimal). Water: 1,389 × 0.70 = 972.3 g. Salt: 1,389 × 0.02 = 27.8 g. Yeast: 1,389 × 0.008 = 11.1 g.
  6. Step 6 — Verify: 1,389 + 972.3 + 27.8 + 11.1 = 2,400.2 g ≈ 2,400 g. ✓
Answer: Flour: 1,389 g | Water: 972 g | Salt: 28 g | Instant yeast: 11 g (all rounded to the nearest gram).
2. You need 18 dinner rolls, each with a scaled dough weight of 60 g before baking. Your formula's total baker's percentage is 165%. What flour weight do you need? Add 5% extra dough to account for scaling loss.
  1. Step 1 — Find the net dough weight needed: 18 rolls × 60 g = 1,080 g.
  2. Step 2 — Add 5% overage for scaling loss: 1,080 × 1.05 = 1,134 g total dough weight needed.
  3. Step 3 — Convert total baker's percentage to a decimal: 165 ÷ 100 = 1.65.
  4. Step 4 — Divide total dough weight by the decimal to find flour weight: 1,134 ÷ 1.65 = 687.3 g (round to 687 g).
Answer: You need approximately 687 g of flour for this batch.
3. A bakery opening is at 7:00 a.m. Whole-wheat sandwich loaves require: mixing 20 min, bulk fermentation 90 min, divide and pre-shape 15 min, bench rest 20 min, final shape 10 min, final proof 60 min, bake 35 min, cool 30 min. What is the latest time mixing must begin?
  1. Step 1 — List all durations: mix 20, bulk ferment 90, divide/pre-shape 15, bench rest 20, final shape 10, final proof 60, bake 35, cool 30. Total = 280 minutes.
  2. Step 2 — Convert 280 minutes to hours and minutes: 280 ÷ 60 = 4 hours 40 minutes.
  3. Step 3 — Subtract from the 7:00 a.m. finish time: 7:00 a.m. − 4 hours 40 minutes = 2:20 a.m.
  4. Step 4 — Mixing must begin no later than 2:20 a.m. to have loaves cooled and ready at 7:00 a.m.
Answer: Mixing must begin by 2:20 a.m.
4. You bake 12 dinner rolls; the target unit weight after baking is 52 g. You weigh a sample of 5 rolls and get: 49 g, 51 g, 53 g, 50 g, 48 g. Calculate the average weight and state whether this batch passes or fails a ±5 g tolerance.
  1. Step 1 — Add the sample weights: 49 + 51 + 53 + 50 + 48 = 251 g.
  2. Step 2 — Divide by the number of samples: 251 ÷ 5 = 50.2 g average.
  3. Step 3 — Calculate the tolerance range: target 52 g ± 5 g = 47 g to 57 g.
  4. Step 4 — Check all individual weights against the range: 49, 51, 53, 50, 48 — all fall between 47 g and 57 g.
  5. Step 5 — Check the average: 50.2 g is within the 47–57 g range.
  6. Step 6 — The batch passes on weight, but the average is 1.8 g below target, suggesting a slight under-scale or excess bake-off. Note this in the QC report as a minor deviation and propose checking pre-bake dough piece weight next production run.
Answer: Average weight: 50.2 g. All individual weights are within the ±5 g tolerance. Batch passes weight QC, with a minor deviation noted.
