Quality

A documented quality management system, built around traceability from the first job.

What is documented

A quality manual and seventeen written procedures covering:

• Document and record control
• Contract review, including customer requirement flowdown
• Purchasing and supplier approval — no purchasing from an unapproved supplier
• Nonconformance and corrective action, including effectiveness verification rather than just "action taken"
• Inspection and test, receiving inspection, and first article inspection
• Calibration and gage control
• Preventive maintenance
• Configuration management and traceability
• Counterfeit parts prevention
• Foreign object debris (FOD) prevention
• Export control
• Risk management

Traceability

Three identifiers, kept deliberately separate. A part number owns the design data and never changes when the part is revised. A job number covers exactly one manufacturing event — one part number, one lot — and owns that lot's traveler, material certifications, and inspection records. A Certificate of Conformance is issued against that job.

Keeping those three separate is what lets a question two years after shipment be answered from the records — which material certification, which revision, which inspection, on which date.

Inspection

First article, in-process and final inspection are recorded against the job, with the inspection evidence — including photographs where a photograph is the evidence, such as a leak-check readout — filed with the job and referenced by filename from the traveler.

Why the system looks like this

Devlen is run by a mechanical engineer who spent a career designing accelerator components and working with an accelerator laboratory machine shop to get them made — which means the documentation here is written from the point of view of the engineer who receives the part, not just the shop that ships it.

That is the useful half of the experience. Knowing which drawing notes actually drive a process, what a supplier needs to be told, and what an engineer will want to see in the paperwork is the difference between a quality system that satisfies an auditor and one that answers a customer's question.
