This page is for anyone who has followed Course 5 (Tech Packs and Costable Specifications) and now needs to decide whether a complete, submitted tech pack is actually ready for production. At work, nobody assembles a tech pack by checking its sections in isolation and stopping there. A product-development team or a buyer opens one finished document and decides whether every section is not only present, but consistent with every other section. Without that whole-document check, a person can confirm each section passes its own specific test and still approve a document that contradicts itself between two of those sections.
This lesson does not teach a new fact about tech packs. It assembles lesson 5.1 (what a tech pack is), lesson 5.2 (building a bill of materials), lesson 5.3 (adding construction and measurement detail), and lesson 5.4 (adding grading and packing) into one full-assembly audit, then applies it to a domestic Make-to-Stock batch Cedar & Co. is planning, loosely based on Order A's construction. This lesson mainly teaches a decision: given a real, complete-looking tech pack, is it actually ready for production.
You need: lessons 5.1 to 5.4 of this course. If you have not read them, the key terms below and the method's steps restate what each one covers.
By the end of this lesson you can:
Not covered here: how the next track's lessons build on a completed, costable tech pack once production is confirmed ready to proceed.
| Term | Meaning |
|---|---|
| Tech pack | The complete document set a factory needs to make a garment: bill of materials, construction detail, measurement spec, grading rules, and labelling/packing instructions. |
| Costable specification | A tech pack detailed enough that a factory can calculate an accurate cost from it, with no missing information forcing a guess. |
| Bill of materials | The list of every material and cost component in a garment, fabric, trims, making, overhead, and profit, with its own cost, that together build up to the total FOB price. |
| Construction detail | The tech pack section naming the stitch class, seam type, and seam allowance for each construction point on a garment. |
| Grading rules | The tech pack section stating the base size and the grade rule applied to produce every other size in the range. |
| Labelling and packing | The tech pack section stating what labels, packaging, and carton marking a garment needs, including any cost-relevant packing choices. |
| Full-assembly audit | A single check confirming all five tech pack sections are present and consistent with each other, not checked one section at a time in isolation. |
This closing lesson does not add a new fact about any one tech pack section. It combines four things this course already taught into one full-assembly audit: (1) all five sections present (lesson 5.1); (2) the bill of materials summing correctly (lesson 5.2); (3) construction and measurement detail reusing established conventions (lesson 5.3); (4) grading rules and labelling/packing complete and internally consistent with the bill of materials (lesson 5.4). A tech pack that passes every one of these four checks separately can still fail the audit, if any two sections contradict each other once the whole document is read together.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| Complete, consistent, costable tech pack | All five sections present, each internally consistent with the others. | Ready for production: a factory can cost it, sew it, size it, and pack it without guessing at anything. |
| Complete but inconsistent tech pack | All five sections present, but a labelling/costing mismatch (lesson 5.4's trap) or a construction deviation without a stated reason (lesson 5.3's trap) makes it unreliable. | Looks finished on a section-by-section read, but a mismatch between two sections means the actual production cost or method will differ from what was quoted. |
| Incomplete tech pack | One or more of the five sections missing entirely. | Cannot be assembled into a working document at all, regardless of how good the present sections are. |
| Order A's own case | Its own fixed figures across costing, construction, measurement, grading, and packing anchor the worked example of a complete, consistent, costable tech pack. | Shows all five sections can trace back to the same fixed reference order at once, so an inconsistency is a gap in the document, not an unavoidable limit of the method. |
None of the three shapes above is "close enough" to another. A complete but inconsistent tech pack is not a complete, costable one; it only looks that way until the whole document is checked together.
The case we followCedar & Co. is planning a domestic Make-to-Stock batch of T-shirts, loosely based on Order A's own construction, for its own forecast rather than a single buyer's order. Before the batch proceeds, Cedar & Co. asks its product-development team to assemble a complete tech pack covering all five sections, then submit it for approval.
The product-development team submits a tech pack with all five sections present: a bill of materials that sums correctly to Order A's own fixed FOB 3.20, construction detail matching Order A's established conventions, a complete measurement spec covering all four points of measure, and complete grading rules stating both the base size and the grade-per-point amounts. Read section by section, every one of these four checks passes. But the labelling section specifies a woven label, while the bill of materials still costs a printed label at USD 0.03, the exact mismatch this course's lesson 5.4 warned against.
The worked numberOrder A's own fixed figures show what a fully consistent tech pack looks like once every section is traced back to the same reference order.
Four of the five sections trace back to Order A's own fixed figures without a single change. Only the labelling section breaks that consistency, and only a full-assembly audit that reads the bill of materials and the labelling section together, rather than each on its own, catches it.
The methodA common mistake is running lesson 5.1's completeness check, lesson 5.2's sum-and-verify check, lesson 5.3's reuse-and-verify check, and lesson 5.4's completeness-and-consistency check, one after another, and treating four separate passes as proof the whole document is ready. Each check only looks at its own section. A cross-section inconsistency, such as a labelling choice that does not match the bill of materials' costed assumption, only becomes visible when the whole document is reviewed together, not section by section in isolation.
This lesson brings together everything this course, and this whole track, has taught, in one check anyone can run on a finished tech pack before approving it. Check that all five parts are there: the cost list, how the garment is sewn, its measurements, its size rules, and its labels and packing. Then check each part again, but this time against the others, not on its own. A tech pack can get every single part right by itself and still have two parts that do not agree with each other, such as a cost list that assumes one kind of label while the labelling instructions ask for a different, more expensive one. Only checking the whole document together, not one part at a time, catches a mistake like that before it reaches the factory floor.
Cedar & Co.'s product-development team submits a tech pack for the domestic Make-to-Stock batch, based on Order A's own construction, ahead of production sign-off. All five sections are present: a bill of materials, construction detail, a measurement spec, grading rules, and a labelling/packing section.
Is this tech pack ready for production? Decide before you open the decision.
Not yet. Every section individually passes its own specific check: all five sections are present, the bill of materials sums correctly to FOB 3.20, construction and measurements match established conventions, and the grading rules are complete.
But the labelling section specifies a woven label, while the bill of materials still costs a printed label at USD 0.03, part of the trims figure that sums into the FOB total. A woven label is typically a different, often higher, cost than a printed label, so this is a real mismatch between what was costed and what the labelling section actually asks for, an inconsistency only visible when the tech pack is reviewed as a whole, not section by section.
Either the bill of materials must be updated to reflect the woven label's actual cost, or the labelling section must be corrected back to the printed label the costing assumed, before the tech pack is ready for production. If Cedar & Co. proceeds on this tech pack as submitted, the factory will source whichever label the labelling section names, and the batch's actual cost will silently diverge from the FOB 3.20 that was quoted.
This is framed qualitatively, tying together the whole course and the whole track, with the concrete USD 0.03 printed-label figure as the anchor. Approving a tech pack because each of its five sections, checked separately, appears to pass its own specific check risks shipping an internal contradiction into production, discovered only once the factory sources a woven label that was never costed into the bill of materials' 0.03 printed-label line. On a batch of any real size, the difference between a printed and a woven label multiplies across every piece, silently changing the order's actual cost from what was quoted and approved. This is the real, but not separately quantified, cost this closing lesson's full-assembly audit method is designed to prevent, for this course and for every tech pack this whole track has taught you to assemble.
This course's workbook is the tech pack itself. Its Tech Pack Sections sheet has one row per section, with columns for where each section's figures come from, whether it is complete, and any notes. The example rows already filled in show Order A's own five sections, each traced to its fixed source, as this lesson's worked number set out. Download the workbook, copy its rows into your order's file, and run the full-assembly audit across every row before treating the tech pack as ready.
| Workbook row | Order A (filled in) | Your order |
|---|---|---|
| Bill of materials | Complete, sums to FOB 3.20 | |
| Construction detail | Complete, established conventions | |
| Measurement spec | Complete, all four points | |
| Grading rules | Complete, base size and grade rule | |
| Labelling and packing | Complete, matches the bill of materials |
1. What five sections must a complete tech pack have?
2. Can a tech pack pass every individual section check and still not be ready for production?
3. A different order's tech pack has all five sections present and each section, checked alone, passes its own test. What does a full-assembly audit still need to check?

You now have a one-step audit that checks a whole tech pack, not just its individual sections, before an order proceeds. This closes Track 5 (Product, Construction and Tech Packs). The next track opens a new stage of the order, building on the complete, costable specification this track has taught you to assemble. Back to the course map
