A Engineering documentation

Audit-Ready SOPs, Work Instructions and Validation Records for Manufacturers.

You send the raw material — a recording, a rough draft, a walk-through of how it's actually done. You receive a structured, toleranced, audit-ready document written by an engineer who knows what a reviewer will look for.

01 What we write

Five documents, one standard.

02 The difference, made visible

What we caught that the notes left out.

Same source notes, two outputs. A transcriber gives you the left column. An engineer gives you the right — and the right column is the one that survives an audit. Toggle the engineering on.

WI-INJ-022 · INJECTION MOULD CHANGEOVER
What the operator told us

"Swap the mould, bolt it in, set the temps off the last sheet, run a few shots and if they look ok we're good to start the batch."

What we delivered
1.2 Verify mould ID against work order — scan + 2-point check Caught: "swap the mould" assumes the right mould. Wrong-tool runs are a top scrap cause; we made identity a verified step, not an assumption.
2.4 Torque clamp bolts to spec, star pattern — 95 ± 5 N·m Caught: "bolt it in" has no spec. Under-torque drops moulds; over-torque cracks plates. We specified value, sequence and a calibrated tool.
3.1 Set process from validated sheet — not "last run" Caught: "off the last sheet" propagates drift. We tied setpoints to the validated master, with a deviation log if they differ.
4.0 First-article inspection before batch — 3 pcs · CTQ dims · QA release Added: "if they look ok" is not acceptance. We defined sample size, the critical dimensions to measure, and who signs to release.
THE LEFT COLUMN READS FINE. THE RIGHT COLUMN IS WHY YOU PASS THE AUDIT AND KEEP THE LINE RUNNING.
03 How it works

One exchange. Then you get the document.

STEP 01

You send raw material

A recording, a rough draft, a marked-up drawing, or a 20-minute walk-through of how it's really done. We work from your format — no template for you to fill in.

STEP 02

One round of questions

We scope it, quote it, and ask one focused round of engineering questions if needed. No kickoff calls, no discovery theatre. You approve the scope before we write.

STEP 03

You receive the deliverable

A finished, formatted, audit-ready document in your house style — typically within five business days. One round of revisions included.

05 Common questions

Frequently asked about engineering documentation.

How long does it take to write a manufacturing SOP?

A single SOP or work instruction typically takes three to five business days from receipt of your source material. That material can be a recording, a rough draft, or a process walk-through. More complex procedures with multiple sign-off levels may take up to seven days. Turnaround is agreed in the scope before work begins.

What information do I need to provide to get a document written?

Any raw material works: a voice recording of how the process is actually done, a rough draft, a marked-up drawing, or a 20-minute walk-through video. You do not need to fill in a template. The engineer asks one focused round of questions after reviewing your material, then writes the document from that.

Will the documents pass an ISO 13485 or FDA audit?

Documents are written to the standard used in ISO 13485 and MDR regulated environments. That includes defined parameters with tolerances, two-party sign-offs, deviation routing, and traceability to incoming material. Every clause is written as a verifiable record, not a description. Whether a specific document satisfies your QMS depends on your internal quality system; the scope review can align to your document control requirements.

What types of manufacturers do you work with?

Primarily medical device manufacturers under ISO 13485 and MDR, consumer electronics manufacturers with high-volume production lines, and industrial equipment OEMs. The background is deepest in process validation, equipment qualification, and new-product introduction, so the fit is strongest where those are the challenges.
