This page is for a merchandiser or production manager at a garment factory who must decide what happens to every checkpoint still ahead once an earlier one has already slipped past the point of simple absorption. At work, this person is handed a schedule that no longer matches reality: one checkpoint is already late, its buffer already used up, and every checkpoint after it needs a fresh decision, not just a note that it is "behind." This is chiefly a decision-flow skill: choosing, for the checkpoints still ahead, whether to compress a stage, use a costlier option, or accept that the ship date itself must move, and rebuilding the plan around whichever choice is made. Without rebuilding the plan properly, a factory can keep chasing an old schedule that a slip has already made impossible to meet.
You need: Lesson 3's method for telling a recoverable delay from a non-recoverable one. Useful, not required.
By the end of this lesson you can:
Not covered here: the formal claim or chargeback a buyer may raise over a missed ship date, and the wider order-booking decisions a factory makes across its whole floor (both covered later in Track 11).
| Term | Meaning |
|---|---|
| Recoverable delay | A stage finishes late, but a buffer later in the timeline absorbs it without moving the final date. |
| Non-recoverable delay | A stage finishes late with no buffer left, so the final date must move or a costlier recovery option must be used. |
| Buffer | Extra days or weeks added to a timeline on purpose, to absorb a likely delay. |
| Escalate | Telling the people who need to know, early, that a delay may change the delivery date, instead of waiting for it to happen. |
| Critical path | The chain of sequential stages that sets the shortest possible total time for the order. |
| Production tracking | Comparing a stage's actual finish date against its planned date throughout production, to catch a delay while it can still be fixed. |
A non-recoverable delay means the original schedule for every checkpoint still ahead is no longer realistic; it was built assuming the buffer that has now been used up. Rebuilding the critical path means choosing, deliberately, one of a small set of options for the remaining checkpoints, then recalculating each remaining deadline around that choice, rather than simply moving every date back by the size of the slip and hoping it still works. The three realistic options are: compress a later stage (for example, overtime to shorten sewing), pay for a costlier substitute (for example, air freight instead of sea freight), or move the ship date itself. Each option has its own cost, and the choice is not automatic; it depends on which option costs least against what the order is actually worth.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| Export order vs. domestic order | An export order's ship date is fixed by a buyer's own contract, so moving it needs a formal conversation and often a claim; a domestic Make to Stock brand's own shop-floor date can sometimes move with only an internal decision, since no outside buyer holds a contract over it. | Treating a domestic date as if it needed the same formal renegotiation as an export ship date adds delay and cost a domestic decision does not actually require. |
| A hybrid floor vs. a single-order floor | Delta Garments' hybrid line runs Order A and a domestic run together; a slip on Order A's own fabric can tempt a planner to compress the domestic run's own stage instead, borrowing capacity from an order that was not actually delayed. | Fixing one order's slip by quietly delaying a different order on the same floor only moves the problem, and the second order's own buyer or brand still needs to know. |
| Compressing a stage vs. substituting a costlier method | Compressing sewing with overtime, at Order A's own fixed overtime rate, usually costs far less than switching the whole shipment to air freight. | Reaching straight for the most expensive option, air freight, without first pricing a cheaper compression option wastes money the order's own margin may not support. |
| A single slipped checkpoint vs. more than one on the same order | Order A's own schedule can, in a worse case, see both fabric in-house and sewing complete slip in sequence, compounding the delay rather than a single isolated slip. | Rebuilding around a single slip's cost while a second slip is already forming leaves the new plan out of date again almost immediately. |
| Socks, terry, and home-textile product families | A hosiery, terry, or bedding order rebuilds its own remaining checkpoints the same way, using that product's own compressible stage, such as linking or finishing, in place of sewing. | The three-option rebuilding method does not change by product family; only which stage can realistically be compressed changes. |
Delta Garments runs Order A alongside a domestic Make to Stock run on the same hybrid line. Order A's fabric-in-house checkpoint, planned for week 7, actually finishes six days into week 8, and Mona confirms the schedule's own five-day buffer ahead of cutting and sewing has already been fully used, making this a non-recoverable delay against the week 10 ex-factory ship date. Karim, the production manager, must choose one of the three options for the checkpoints still ahead: overtime to compress sewing, air freight to shorten the shipping stage instead, or asking Sara, the buyer at Northline Apparel, to move the ship date.
The worked numberOvertime at USD 2,250 recovers the same six-day slip that air freight would cost USD 27,000 to recover instead, a saving of USD 24,750 on this order alone. Karim chooses overtime first, and only considers air freight, or asking Sara to move the ship date, if overtime alone cannot fully close the six-day gap once sewing capacity on the hybrid line is actually checked.
The methodA common mistake, once a slip is confirmed, is simply adding the number of days late to every remaining checkpoint's deadline and calling the schedule rebuilt, without checking whether cutting, sewing, or shipping capacity is actually available on those new dates, or whether a cheaper recovery option would have avoided moving them at all. A pushed-back schedule that nobody has actually checked against real floor capacity is not a rebuilt plan; it is the same problem, written in different numbers, waiting to be discovered again once the new dates arrive.
Once a delay has used up all its buffer, the plan for every stage still ahead has to be rebuilt on purpose, not just pushed back by the number of days lost. There are three real choices: speed up a later stage, usually with overtime; pay more for a faster method, such as air freight instead of sea freight; or accept that the final date itself has to move. Each choice has its own cost, and the cheapest one that still works is usually the right one to pick, checked against what the whole order is actually worth. Once a choice is made, every remaining stage's own deadline needs to be worked out again around that choice, and checked against what the factory floor can actually deliver, not just written down and hoped for.
Karim, the production manager, has confirmed Order A's fabric-in-house delay is non-recoverable and must choose the recovery option today.
The two options as Karim has priced and checked them:
Which option should Karim choose for Order A's six-day slip? Decide before you open the decision.
Overtime. It costs USD 24,750 less than air freight and, once checked, does not touch the domestic run's own schedule the following week.
The two facts that decide this are overtime's far lower cost, and the confirmation that it does not compete with the hybrid floor's own domestic run for the same sewing-line time. Had overtime instead required using next week's sewing-line hours, the domestic run's own schedule would need checking before choosing it, since borrowing that capacity would simply move Order A's slip onto a different order sharing the same floor.
Choosing overtime instead of air freight saves USD 24,750 on Order A alone, the difference already calculated above. The further cost at risk is what skipping the capacity check would have cost: if Karim had chosen overtime without confirming it left the domestic run untouched, and the two orders had actually needed the same sewing hours, the domestic run's own shop-floor date could have slipped instead, trading one order's recovered slip for another order's new one, on a floor where both matter. Checking capacity before choosing costs Karim a short conversation with the line supervisor; skipping it risks turning one recovered delay into a second, unplanned one.
This lesson adds the rebuilt deadline, the chosen recovery option, and its cost to the tracker built across Lessons 1 to 3. [Download the tracker](templates/T11-C01-critical-path-tracker.xlsx).
| Milestone | Original deadline | Rebuilt deadline | Recovery option | Cost |
|---|---|---|---|---|
| Cutting and sewing complete | Week 9 | Week 9 (held via overtime) | Overtime | USD 2,250 |
| Ex-factory ship date | Week 10 | Week 10 (unchanged) | None required | — |
1. What does 'rebuilding a critical path' mean, once a delay is confirmed non-recoverable?
2. A different order's slip needs 10 days recovered. Overtime would cost USD 500 per day; a costlier substitute method would cost USD 900 per day for the same recovery. Which option costs less overall, and by how much?

You can now name a critical path's checkpoints, set each one's deadline backward from the ship date, spot a slip early, and rebuild the plan once a slip has happened. The last lesson brings all of this into one complete working tracker. Back to the course map
