Confirming a genuine automation candidate, comparing its own total cost of ownership against the labour cost it replaces, and monitoring a line's own true energy use with a utility submeter are each useful alone, but only produce a workable decision when run together on the same shared line and the same shared volume. This is mainly a process decision, made once a factory is ready to commit to an actual purchase rather than test one step at a time. A factory that runs only one of these three checks in isolation risks approving automation on a volume that alone would not justify it, or reporting an energy figure that was never actually verified.
Delta Garments' own sleeve-attach line runs both Cedar & Co.'s domestic Make to Stock orders and recurring export Make to Order orders like Order A side by side, a hybrid model. Judging automation on either volume alone, without pooling them, can produce the wrong answer for a line that actually carries both.
You need: the automation-candidate test result (Lesson 4.1), the total cost of ownership and break-even volume (Lesson 4.2), and a plan for submetering the line once automated (Lesson 4.3).
By the end of this lesson you can:
Not covered here: the individual tests themselves, already taught in Lessons 4.1 to 4.3.
| Term | Meaning |
|---|---|
| Automation candidate | A task that is well-defined, repetitive and low in commercial judgement, and so a reasonable task to consider automating. |
| Total cost of ownership | A rollout's own total cost plus its own recurring cost over a defined period, used to compare it fairly against an alternative. |
| Technology break-even volume | The number of units or cartons a rollout must process before its own savings equal its own total cost. |
| Utility submeter | A separate meter installed on one line, department or machine group, measuring its own electricity or water use apart from the factory's single main meter. |
| Consumption intensity | A line's own energy or water use divided by the pieces it produced over the same period, giving a per-piece figure comparable across orders. |
Confirming an automation candidate, calculating its own total cost of ownership against the technology break-even volume, and planning a utility submeter for its consumption intensity are each taught separately, but a real hybrid line needs all three run together on its own true pooled volume, domestic and export combined. A decision reached on only one line's own share of that volume can reverse once the line's full, pooled volume is counted.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| One order type per line vs. a shared hybrid line | A line dedicated to a single business model only needs its own volume checked once; a shared hybrid line, like Delta Garments' own sleeve-attach line, needs domestic and export volumes pooled before the break-even check means anything | Judging a shared line by only one of its order types can wrongly reject automation that the line's own full volume would actually justify |
| Export MTO vs. domestic MTS volume on the same line | Export MTO volume on a hybrid line can arrive in large, infrequent batches like Order A's own 15,000 pieces, while domestic MTS volume arrives in smaller, steady monthly batches like Cedar & Co.'s own orders | Pooling volumes that arrive on different schedules still gives one correct annual total, even though the two streams look very different month to month |
| A volume close to the break-even figure vs. far from it | A pooled volume far above or far below the break-even figure gives a clear decision; a pooled volume close to the break-even figure needs the underlying assumptions, like the labour cost rate used, checked more carefully | A close call is exactly where an error in an earlier check, such as using the wrong labour cost figure, can flip the final decision |
| A newly automated line's own energy use vs. its pre-automation baseline | A line's own consumption baseline recorded before automation can change once automated, since a machine may draw power differently from the operators it replaces | A submeter's own reading should be re-checked after automation, not assumed to stay the same as the pre-automation baseline |
| Product families | The same combined method applies whether the goods are apparel, socks and hosiery, knit-to-garment, terry and towels, or home textiles and bedding | A factory new to this combined decision applies the same three checks together regardless of product family |
Delta Garments' sleeve-attach line already passed Lesson 4.1's own automation-candidate test. Lesson 4.2 found that Cedar & Co.'s own domestic volume alone, 48,000 pieces a year, fell short of the 60,000-piece break-even volume. Karim now adds the line's own recurring export volume, similar orders to Order A arriving several times a year, before deciding whether to approve the purchase, and plans a utility submeter for the line once it is automated, applying Lesson 4.3's own method.
Running the automation-candidate test, the total-cost-of-ownership check and the submeter plan together on the line's own true combined volume, rather than on Cedar & Co.'s domestic share alone, is what lets Delta Garments reach a workable final decision.
The worked numberCedar & Co.'s own domestic volume alone, 48,000 pieces, fell 12,000 pieces short of the break-even volume in Lesson 4.2, but pooling it with the line's own recurring export volume of 60,000 pieces gives 108,000 pieces a year, well clear of the 60,000-piece figure. Once the automated unit is installed, Delta Garments plans a utility submeter on the line so its own actual post-automation consumption intensity can be tracked directly, rather than assumed to match its pre-automation baseline.
A common mistake is running the break-even check on a hybrid line using only the volume from one business model, such as Cedar & Co.'s own domestic orders, and rejecting automation because that volume alone falls short. This ignores the line's own recurring export volume sharing the same task, which can be exactly what pushes the pooled total past the break-even figure. The fix is pooling every order type's own volume sharing the line before comparing it against the break-even volume, exactly as this lesson's method does.
Deciding whether to automate a task, checking whether the machine pays for itself, and tracking its real energy use afterward are three separate questions this course has taught one at a time. On a real line that carries more than one kind of order, they must be answered together using that line's own true combined volume, or the answer can come out wrong. Delta Garments' sleeve-attach line shows this: Cedar & Co.'s own domestic orders alone did not reach the volume needed to pay for automation, but adding the line's own regular export orders pushed the combined total well past it, so automation goes ahead and the line's real energy use is now tracked directly with its own meter.
Omar, the owner of Cedar & Co., reviews Lesson 4.2's own finding that his 48,000-piece domestic volume fell short of the 60,000-piece break-even volume, and asks Karim whether that means the automation should be rejected outright for the sleeve-attach line his own orders run on. The facts in front of Karim:
The question relayed to Karim:
Should the automation be rejected because Cedar & Co.'s own domestic volume alone falls short of the break-even volume? Decide before you open the decision.
No, the automation should not be rejected; the line's own pooled hybrid volume of 108,000 pieces clears the 60,000-piece break-even volume even though Cedar & Co.'s own domestic share alone does not.
Two facts decide this. First, this lesson's rule requires pooling every order type's own volume sharing a hybrid line before comparing it against the break-even volume, not judging one order type in isolation. Second, the line's own recurring export volume of about 60,000 pieces a year, once added to Cedar & Co.'s own 48,000 pieces, reaches 108,000 pieces, well clear of the 60,000-piece figure.
Rejecting automation based on Cedar & Co.'s own domestic share alone ignores exactly the pooled-volume method this lesson exists to apply.
Rejecting automation on Cedar & Co.'s own domestic volume alone would forfeit a first-year net saving of USD 5,760 that the line's true pooled volume actually earns once its own USD 7,200 total cost of ownership is covered, a saving that recurs every year the pooled volume stays at or above its current level.

1. Why does pooling Cedar & Co.'s domestic volume with the line's own export volume change the automation decision from Lesson 4.2?
2. A hybrid line's break-even volume is 50,000 pieces a year. Domestic orders contribute 22,000 pieces and export orders contribute 25,000 pieces. Does the pooled volume clear the break-even figure?
