This page teaches a merchandiser or planner how to compare a material requirement plan against what a mill has actually confirmed it can deliver, so a shortfall is caught before the cutting room, not on the day cutting is due to start. It is for anyone who checks a fabric confirmation against a plan rather than assuming a plan always becomes reality. It mainly teaches a decision: whether a confirmed quantity is enough, and what to do when it is not.
At work, a domestic brand planning to its own forecast, such as Cedar & Co., cannot assume a mill will always confirm exactly the quantity requested. A mill's own yarn supply, machine schedule, or a shared dye lot with another customer's order can all reduce what it is actually able to confirm, even after a purchase order has been placed. Without checking a mill's confirmation against the plan, a shortfall is only discovered once fabric arrives at the factory gate, far too late to fix without delaying cutting.
This lesson uses an illustrative domestic order for Cedar & Co., since Order A's own fixed fabric plan carries no shortfall to work through; the method taught here applies equally to Order A's own export figures whenever a real shortfall does occur.
You need: Lesson 13.3.3's method for adding lead time and safety stock to a bare material requirement.
By the end of this lesson you can:
Not covered here: calculating the bare material requirement itself (Lesson 13.3.1), calculating lead time and safety stock (Lesson 13.3.3), assembling every material on an order into one complete plan (Lesson 13.3.5).
| Term | Meaning |
|---|---|
| Bill of materials | The list of every material and cost component in a garment, with its cost, used to build up the FOB price. |
| Total fabric requirement | The full quantity of fabric an order needs, calculated from per-piece consumption times order quantity. |
| Safety stock | An extra quantity of material planned on top of the bare requirement, to cover ordinary variation in a supplier's own delivery or a mill's own production run without stopping the cutting room. |
| Make to Stock (MTS) | Producing against the seller's own sales forecast, rather than a single confirmed buyer order. |
Once a material requirement plan states a total planned quantity, bare requirement plus safety stock, that figure is not the end of the planning work. The mill's own confirmation, once it responds to the purchase order, must be checked against that same total. If the mill confirms less than the plan calls for, the difference is a shortfall, and it must be caught and acted on before the day cutting is due to start, not discovered on that day.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| Shortfall smaller than safety stock | A small shortfall that safety stock alone can absorb without any further action | The plan still delivers enough fabric for cutting, even though the mill confirmed less than the full planned quantity |
| Shortfall larger than safety stock | A shortfall that eats into safety stock and still leaves the plan short of the bare requirement | Further action is needed, a second supplier, an expedited partial delivery, or a delayed cutting date |
| Domestic MTS order | Cedar & Co.'s illustrative order, planned against its own forecast, checked against the mill's confirmation before cutting | A forecast-based order has no buyer waiting on a fixed date, but a shortfall still delays the brand's own shop delivery |
| Export MTO order | Order A's own fixed 15,000-piece order, checked the same way against Rowad Knits' confirmation | A shortfall on an export order risks a fixed, contracted delivery date agreed with Northline Apparel |
| Related product families | A hosiery mill confirming less yarn than a sock order's plan calls for, a home-textile converter confirming less sheeting fabric than a bedding order's plan calls for | The same compare-and-act method applies wherever a mill's confirmation can fall short of a plan's total |
Cedar & Co.'s illustrative order plans for 1,080 kg of single-jersey fabric, its own bare requirement with no safety stock added for this teaching example. Once the mill responds to the purchase order, it confirms only 950 kg, less than the plan calls for. Cedar & Co.'s planner must catch this shortfall and decide what to do about it before the date its own cutting is due to start.
Cedar & Co. plans to its own forecast rather than to one buyer's confirmed order, so no external buyer is waiting on a fixed contracted date the way Northline Apparel waits on Order A. This does not make a shortfall harmless; it only changes who feels the delay. A forecast-based order still has its own planned shop-delivery date, and a shortfall left unchecked pushes that date back just as surely as a missed export deadline would.
The worked numberThis example is entirely illustrative, following the method Order A's own fixed figures already established elsewhere in this course. The plan's total requirement:
The mill's actual confirmed quantity, illustratively:
The shortfall is 130 kg, the amount by which the mill's confirmation falls short of the plan's total, worked out live on this course's material requirement planner rather than discovered only once fabric arrives.
A shortfall does not always mean the mill has failed to perform. A shared dye lot, a yarn delay upstream at Nile Spinning, or an ordinary roll-end loss can each reduce what a mill is able to confirm, without any error on the mill's own part. What matters for the planner is not assigning blame but catching the gap early enough to still have options, since every option, a second supplier, an expedited run, or a revised date, needs lead time of its own to carry out.
The methodA common mistake is treating a mill's confirmation as a formality to be filed rather than a figure that must be checked against the plan the moment it arrives. A confirmation that quietly states a smaller quantity than requested can sit unread against the original plan for weeks, since nothing in the confirmation itself demands urgent attention. By the time fabric physically arrives and is weighed against the bare requirement, there is no lead time left to place a second order or adjust the cutting date.
This lesson shows how to catch a fabric shortage early instead of finding out about it too late. After a plan says how much fabric is needed, the mill eventually confirms how much it can actually supply. That confirmed amount has to be compared against the plan right away, not filed away and checked later. If the mill is confirming less than the plan needs, that gap is the shortfall, and it should be spotted as soon as the confirmation comes in, while there is still time to order more, ask another mill, or move the cutting date. Waiting until the fabric physically arrives to check is too late to do anything but delay.
Omar's illustrative domestic order plans for 1,080 kg of fabric, with cutting due to start in three weeks. The mill's confirmation arrives stating only 950 kg, less than the plan calls for. Cedar & Co.'s planner must decide what to do with two weeks still left before cutting.
Should Cedar & Co.'s planner accept the 950 kg confirmation as final, or act on the shortfall while two weeks remain?
Cedar & Co.'s planner should act on the shortfall now, while two weeks still remain before cutting. The shortfall, 1,080 minus 950, is 130 kg, which the mill's confirmation states is not available from the same dye lot. With two weeks left, the planner still has time to ask a second mill for the remaining 130 kg, request an expedited top-up run from the same mill, or, if neither is possible in time, move the cutting date back rather than start cutting short. Accepting the confirmation as final without acting removes all three of these options, since each one needs time this early warning still provides.
A 130 kg shortfall caught with two weeks still remaining before cutting costs little more than the planner's own time to source a top-up quantity or adjust a schedule. The same 130 kg shortfall discovered only once fabric physically arrives, on the day cutting is due to start, costs far more.
The illustrative value, in USD, of the missing 130 kg of fabric at Order A's own fixed fabric price of USD 5.60 per kg (section 7), reused here to illustrate the shortfall's scale, not a claimed cost for Cedar & Co.'s own fabric.
Beyond the fabric's own value, a cutting room that cannot start on schedule idles cutters and downstream sewing lines while a second order is placed and its own lead time is waited out, a cost in idle time that catching the shortfall two weeks early avoids entirely.
The Material requirement planner (this course's workbook) holds the "Shortfall Check" sheet, which reads a plan's total planned quantity and a mill's actual confirmed quantity, then calculates and flags any shortfall automatically as a live formula.
