Technical breakdown
When a factory sends back questions, the instinct is to read them as resistance. They are not. They are the production team telling you exactly which parts of your documentation they cannot execute without making a decision you did not authorise them to make.
Factories are built for repeatability and efficiency. They do not want to interpret, infer, or guess. When the instructions are clear, they produce. When the instructions are ambiguous, they stop and ask - or worse, they proceed with their own interpretation and produce something you did not expect.
If your handoffs consistently generate questions, the documentation is generating them.
The four gaps that cause most pushback
Ambiguous construction. Designers often specify the result but not the method. “Clean interior finish” is a description of an outcome, not an instruction. It tells the factory nothing about which seam type to use, what the stitch density should be, or in what order operations should be performed. When the method is not specified, the factory chooses the most efficient one available to them - which may not be the one that achieves your intended result.
Conflicting data across documents. A tech pack typically contains a sketch, a measurement table, and a BOM. If these three sources do not agree, the factory cannot proceed without confirmation. A sketch showing a 25 mm button and a BOM listing 20 mm buttons is not a minor discrepancy - it is a production stop. The factory will not choose which document is correct. They will wait for you to tell them.
Instructions that are not manufacturable. Sometimes a detail that looks straightforward in a sketch is physically difficult to execute on production machinery. A pocket placed directly over a bulked seam, or a topstitch that must begin at an inside corner - these create quality problems that the factory can predict before cutting. When they flag these issues, they are protecting the outcome. The correct response is to engage with the concern, not to insist the sketch is right.
Vague material specifications. “High-quality cotton” is not a specification. “130 gsm, 100% cotton poplin, pre-washed, colourfast to Grade 4” is a specification. When material descriptions are qualitative rather than technical, the factory sources what they think meets the intention. What arrives is often different from what was imagined.
The standard to aim for
A production-ready tech pack should be executable by someone who has never seen the design before and cannot ask any questions. If a stranger can read the document and assemble the garment without ambiguity, the documentation is ready. If they need to make assumptions at any point, the documentation is not.
This is not a perfectionist standard. It is a practical one. Every question a factory has to send is a delay. Every answer that requires a revision is another delay. The time spent closing documentation gaps before handoff is a fraction of the time spent managing back-and-forth after it.
How to communicate with precision
Moving from ambiguous to precise is largely a language shift.
- Not: “Make this look premium” - but: “Single-needle lockstitch, 12 stitches per inch, self-thread matching pantone reference”
- Not: “Good quality interlining” - but: “Woven fusible interlining, 60 gsm, applied to collar stand and cuff pieces only”
- Not: “Neat finish on the inside” - but: “French seam throughout, minimum 6 mm finished width”
Technical language removes interpretation. It is the difference between a suggestion and an instruction.
Checklist before sending a technical handoff:
- Construction methods specified - seam type, stitch density, and operation sequence
- Sketch, measurement table, and BOM cross-checked for internal consistency
- All hardware and trim listed with objective specifications - size, weight, finish, and source
- Any complex alignment or matching requirements explicitly flagged and costed
- Potentially unmanufacturable details reviewed with the factory before finalising
- Stranger test performed - can the document be executed without asking a single question?
