Quality
Management.
Certified at the source — not the receiving dock.
Quality is everything in manufacturing. MES quality and sourcing engineers are physically inside the factories where your components are made — verifying every stage from raw material to finished part. Boots on the ground, not reports after the fact.
What does source-based quality management mean at MES?
Source-based quality management means verifying a component where it’s made — not after it arrives. MES stations quality and sourcing engineers inside our partner manufacturing facilities, where they verify raw material, approve first articles, monitor in-process controls, run CMM inspection, and confirm critical features before parts ship.
Most sourcing companies inspect at the receiving dock, or rely on the supplier’s own reporting. By then a problem is already built into thousands of parts. MES catches it on the floor — at the machine, at the press, at the point where it can still be corrected. That’s how we keep PPM low and protect your program timeline.
Our engineers are in the factory. Every day.
The difference between MES and a broker is presence. Our quality and sourcing engineers don’t wait for parts to arrive — they’re on the production floor while your components are being made.
When your parts arrive, they’ve already been verified — by an MES engineer who watched them get made.
Raw material sign-off
Confirming alloy, grade, and material certifications before a single part is produced.
First article approval
Validating the first parts against your drawing before the run is released.
In-process monitoring
Watching dimensional trends during production and correcting drift before it becomes a defect.
CMM inspection at the source
Measuring critical features on calibrated equipment, in the plant.
Ship approval
Confirming critical dimensions and documentation before parts leave the building.
How MES manages quality end to end.
In-person engineering oversight
MES quality and sourcing engineers provide on-site oversight at supplier facilities — start-to-finish, from raw material through final inspection. Your quality isn’t outsourced to the supplier’s word.
Precision measurement & inspection
Industry-leading metrology for exact measurement and inspection — CMM dimensional verification, first article inspection reports (FAIR), gauging, and in-process checks against your drawing and GD&T.
Customer-approved tooling design
Tooling is designed, reviewed, and approved with your team before production — so parts are right the first time and expensive redesigns are caught before steel is cut.
Continuous communication
Proactive, ongoing communication on quality status, dimensional results, and any issue the moment it surfaces — so there are never surprises at your dock.
Integrated supply chain management
Best-in-class supply chain management wraps around quality — a dedicated specialist and planner who tie inspection, inventory, and on-time delivery into a single accountable program.
Quality starts with the right supplier
Every MES supplier is identified, vetted, and developed by the same team that verifies your parts.
Start-to-finish quality, at every stage.
Five checkpoints between raw material and your dock — each one verified by an MES engineer before the next begins.
Documentation isn’t an afterthought — records travel with every order.
Raw material
Material grade and certifications verified before production begins.
Tooling & first article
Customer-approved tooling; first articles validated against your drawing.
In-process controls
Dimensional trends monitored live during the run to keep PPM low.
Final inspection
Critical features confirmed on CMM at the source before parts ship.
Documentation
CMM results, material certs, and inspection records travel with every order.
Quality you can certify.
MES quality systems and documentation meet the standards regulated supply chains require. MES, Inc. has been ISO 9001:2015 certified since 2009, and supports automotive programs through IATF 16949-certified suppliers.
The MES difference
Every account gets a dedicated supply chain specialist and planner who own quality, inventory, and on-time delivery as one program.
The same standard — everywhere we source.
MES quality and sourcing engineers cover the key manufacturing hubs of Mexico, Europe, Japan, India, China, and Vietnam. Wherever your components are made — including our company-operated Metrics Works facility in Saltillo, Mexico — the standard, the inspection, and the documentation are the same.
Frequently asked questions
MES embeds quality and sourcing engineers inside partner manufacturing facilities. They verify raw material, approve first articles, monitor in-process controls, run CMM inspection, and confirm critical features before parts ship — so quality is verified at the source rather than discovered after delivery.
It means MES engineers are physically present on the production floor while your parts are made — not inspecting at a receiving dock or relying on supplier reports. Problems are caught and corrected during production, which is how MES keeps PPM low.
MES has been ISO 9001:2015 certified since 2009. For automotive programs, MES sources through IATF 16949-certified suppliers and supports the full automotive quality chain — PPAP, control plans, FMEA, and material certifications.
PPAP (Production Part Approval Process) is a formal documentation and approval process — mainly automotive — that confirms a supplier’s process can consistently produce a conforming part. MES manages PPAP submission and the supporting documentation for customers who require it.
Before. MES engineers verify critical dimensions on CMM equipment at the source and confirm documentation before parts leave the facility, so components arrive already verified.
By verifying quality at every stage — raw material, first article, in-process, and final inspection — and correcting dimensional drift during production instead of discovering it after thousands of parts are made.
