This page teaches a merchandiser or planner how to bring every skill in this course together into one complete material requirement plan for a whole order, from the bill of materials to a confirmed, shortfall-checked delivery. It is for anyone who must assemble, not just calculate, a full plan before releasing every purchase order an order needs. It mainly teaches a decision: whether a plan, taken as a whole, is ready to release.
At work, a planner rarely uses this course's four earlier skills one at a time in isolation. A real order needs its bill of materials turned into a material requirement list, any shared-fabric orders combined, lead time and safety stock added, and the mill's confirmation checked against the plan, all before a single purchase order safely goes out. Without assembling all four steps into one plan, a planner can complete some steps correctly and still miss one, leaving the order exposed exactly where the missed step would have caught a problem.
This lesson uses an illustrative domestic order for Cedar & Co. to show every stage of a complete material requirement plan working together, including a shortfall, in one place, following the same method Order A's own fixed figures established in the earlier lessons of this course.
You need: all four earlier lessons of this course: building a material requirement list (13.3.1), combining orders sharing a fabric (13.3.2), adding lead time and safety stock (13.3.3), and spotting a shortfall (13.3.4).
By the end of this lesson you can:
Not covered here: any single step in isolation, each already covered in Lessons 13.3.1 to 13.3.4; costing the materials once quantities are confirmed (Track 1's costing course); booking factory capacity around a confirmed material delivery (Track 11).
| 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. |
| Lead time | The total time from a confirmed order to the goods reaching their destination. |
| 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. |
| Material requirement list | The full list of every material an order needs, each in its own unit and quantity, built line by line from the order's bill of materials and its order quantity. |
Each of this course's earlier lessons teaches one step; a complete plan is what results once all four are carried out on the same order, in sequence: the bare requirement first, from the bill of materials; any combining with another order sharing the same fabric next; lead time and safety stock added on top of the resulting total; and finally the mill's actual confirmation checked against that total for any shortfall. A plan missing any one of these four steps is not yet complete, however carefully the other three were done.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| A plan with no issue at any step | A straightforward order whose bare requirement, combined total (if any), and mill confirmation all match cleanly | The plan is ready to release as soon as all four steps are recorded, with nothing further to correct |
| A plan needing a combined purchase order | Two orders sharing a fabric, as in Lesson 13.3.2, folded into one plan before lead time and safety stock are added | Step 2 changes the total that steps 3 and 4 are then carried out against |
| A plan surfacing a shortfall late | A shortfall found only at step 4, after lead time and safety stock were already calculated on the assumption of a full delivery | The earlier three steps still stand; only the final delivery quantity, and possibly the cutting date, needs revising |
| Export MTO plan | Order A's own fixed figures carried through the same four steps, checked against a confirmed export delivery date | A shortfall here risks a fixed, contracted date agreed with Northline Apparel |
| Domestic MTS plan | Cedar & Co.'s illustrative order carried through the same four steps, checked against its own forecast-based schedule | A shortfall here delays the brand's own shop delivery rather than a buyer's contracted date, but the four-step method is identical |
Cedar & Co.'s illustrative order needs its bare fabric requirement calculated from its bill of materials, then lead time and safety stock added, before its mill's actual confirmation is checked for any shortfall. Carrying all four steps through in order, rather than stopping once the bare requirement and safety stock look complete, is what lets Cedar & Co.'s planner catch a shortfall at the final step, with time left to act on it.
The same four steps apply equally to Order A's own export figures, even though Order A's own fixed plan carries no shortfall to work through in this course. A planner moving between an export Make to Order order and a domestic Make to Stock order does not need two different methods; the same bill of materials, lead time, safety stock and shortfall check apply to both, only the underlying figures and who is waiting on the delivery date differ.
The worked numberThis example is entirely illustrative, following the method Order A's own fixed figures already established in this course. Step 1, the bare requirement:
Step 3, safety stock at 10% of the bare requirement:
Step 3 continued, the total planned quantity:
Step 4, the shortfall against the mill's actual confirmation of 1,050 kg:
All four steps, worked through in order on this course's material requirement planner, show a complete plan of 1,188 kg with a 138 kg shortfall still to act on before cutting, rather than a plan that stops at step 3 and assumes the mill will confirm the full amount.
A common mistake is stopping the planning work once lead time and safety stock are calculated, since the plan already looks complete and carefully built at that point. A total planned quantity of 1,188 kg is only a target until the mill's own confirmation is checked against it; assuming the mill will simply deliver the full planned quantity skips the one step, the shortfall check, most likely to catch a real problem before cutting.
This lesson brings everything in this course together into one full plan. First, work out how much material is needed from the garment's own ingredient list. Second, if another order needs the same fabric, add the two together. Third, add extra time for the mill to actually make it, and a small extra amount in case the mill's own output falls slightly short. Fourth, once the mill actually confirms what it can deliver, check that confirmed amount against the plan, because the mill's real answer can still be less than what was asked for. Only once all four of these checks are done is a plan actually finished and ready to act on.
Omar's illustrative domestic order needs a complete material requirement plan before any purchase order goes out. Omar's planner has already built the bare requirement and added safety stock, and now waits on the mill's confirmation before deciding whether the plan is ready.
Is Cedar & Co.'s material requirement plan complete and ready to release, once safety stock has been added but before the mill's confirmation is checked?
No, the plan is not yet complete. Steps 1 through 3 are done correctly, giving a total planned quantity of 1,188 kg, but step 4, checking the mill's actual confirmation against that total, has not yet happened. Once checked, the mill's 1,050 kg confirmation leaves a shortfall of 138 kg (1,188 minus 1,050), which needs a decision, sourcing a top-up quantity or adjusting the cutting date, before Omar's planner can safely release every purchase order the order needs. Following Omar's own instruction, the trim purchase orders should also wait until the fabric side of the plan is fully resolved, since a change to the cutting date affects every material on the order, not only the fabric.
A complete four-step plan costs only the planner's own time to carry out, since every step reuses figures already calculated earlier in the same process. Skipping the final step, and discovering the 138 kg shortfall only once fabric physically arrives, costs far more.
The illustrative value, in USD, of the missing 138 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 within the full plan, not a claimed cost for Cedar & Co.'s own fabric.
Beyond the fabric's own value, an incomplete plan that skips the final check risks the same cutting-room delay covered in Lesson 13.3.4, now compounded by however much of the rest of the order, trims, sewing capacity and shop delivery, was already scheduled around a fabric delivery that never fully arrived.
The Material requirement planner (this course's workbook) brings together every sheet from this course's earlier lessons, "Bill of Materials to Requirement," "Combine Orders," "Lead Time and Safety Stock," and "Shortfall Check," into one "Complete Plan" summary sheet, reading each step's own result forward into the next, automatically, as live formulas.
| Step | Illustrative Cedar & Co. order (filled in) | Your order |
|---|---|---|
| 1. Bare requirement | 1,080 kg | |
| 2. Combined with another order? | No | |
| 3. Safety stock (10%) and total planned | 108 kg → 1,188 kg | |
| 4. Mill's confirmation and shortfall | 1,050 kg → 138 kg shortfall | |
| Ready to release? | Not yet; shortfall needs a decision |
