Tech-Pack Mistakes That Delay Production

1. Using descriptive words instead of measurements

‘Loose sleeve,’ ‘long body’ and ‘small neckline’ mean different things to different people. Replace subjective instructions with finished-garment measurements and clearly drawn points of measure.

If a shape cannot be explained with one number, add a detail sketch, reference curve or pattern instruction. Use one unit system throughout the pack.

2. Flats that disagree with the BOM

A front flat may show snaps while the BOM lists a zip, or the colour page may name a lining absent from the materials list. These conflicts stop purchasing and sampling because the factory cannot know which page is current.

Run a cross-page audit: every visible component should appear in the BOM, and every BOM component should have placement or use instructions.

3. Missing construction and finishing notes

A seam line on a drawing does not identify the seam type, allowance, stitch, edge finish or pressing direction. The sample room may choose its standard method, which can differ from the designer’s quality expectation.

Critical areas for abayas include neck finish, front opening, cuff, pocket reinforcement, side slit, lining attachment and hem. Photograph a benchmark if the finish is difficult to name.

4. Artwork without scale or placement

Factories cannot price or place embroidery from a screenshot. Provide the production file, physical width and height, colour references, technique and distances from stable seam points.

Account for grading: decide whether a motif stays one size across all garments or changes with size. State whether left and right placements are mirrored or identical.

5. Uncontrolled revisions

Sending corrections in several chat messages creates competing instructions. Use one numbered comment sheet, update the tech pack and change the version date. Mark resolved comments instead of deleting the history.

After a fit meeting, verify that the new measurement table, construction notes and artwork pages all reflect the same decision before issuing the next version.

6. The 10-minute handoff audit

Open the exported PDF, not the working file, and review it as a supplier would. Confirm that linked artwork is included, text is legible, units and style codes are consistent, and there are no hidden draft layers.

Finally, list every item still awaiting approval. A clean ‘open issues’ list lets the factory work around known gaps instead of discovering them one by one.

• Style code and version on every page
• Front, back and required detail views
• Measurement method and tolerance
• Complete BOM with colour references
• Construction and artwork instructions
• Packing, label and open-issue status

7. Treat assumptions as controlled open issues

A draft pack may legitimately contain unknown consumption, proposed materials or measurements awaiting a fit sample. The mistake is presenting these assumptions in the same way as approved instructions. A supplier may quote or sample against a placeholder because nothing identifies it as provisional.

Give every unresolved item a status, owner, decision date and affected page. Ask the recipient to acknowledge the open-issue list and state which activities can proceed before closure. When the answer arrives, update the master pack instead of leaving the decision only in email or chat.

• Proposed or approved status
• Decision owner
• Required evidence
• Due date and blocked activity
• Pack pages affected by the answer

8. Define what each sample must prove

A sample request labelled only ‘make first sample’ does not say whether the team is testing silhouette, fit, construction, material, artwork or final production readiness. Reviewers then mix major design changes with minor finishing comments, and the factory cannot tell what is approved for the next stage.

Name the sample stage and acceptance questions before work begins. Record actual measurements, photographed construction details, material references and numbered comments after review. An approved appearance does not automatically approve bulk fabric, graded sizes, packaging or a production process that was not represented in that sample.

9. Diagnose the mistake by its downstream consequence

When a delay occurs, trace it to the decision that could not be made. Missing material identity blocks sourcing or makes quotations incomparable; conflicting flats and construction notes block pattern or sample work; missing measurement methods make fit comments disputed; obsolete revisions create rework after an apparently correct handoff.

Use a simple diagnostic register with the observed question, source gap, affected activity, owner, correction and prevention check. This distinguishes a one-off clarification from a system problem that should change the template or review process.

• Supplier question or failed output
• Missing or conflicting source instruction
• Cost, quality or timing consequence
• Immediate correction owner
• Future preflight check

10. Use a controlled correction workflow

First pause only the work affected by the error and confirm which released revision the supplier holds. Consolidate the correction into one numbered change record, assess whether measurements, BOM, colourways, artwork or cost are also affected, then update the controlled pack and its revision history.

Issue one replacement file with a change summary and withdraw the superseded release from active use. Ask the supplier to acknowledge the new revision and restate any cost or schedule effect before restarting. After closure, add a prevention checkpoint to the relevant internal review rather than relying on memory.

• Confirm current released revision
• Identify every dependent page and file
• Approve the correction and commercial effect
• Issue one dated replacement
• Withdraw superseded instructions
• Record a prevention check
