Paper SPC can't prove control to an OEM
Control charts maintained in 12-tab spreadsheets are slow, error-prone, and impossible to audit. When an OEM asks for capability evidence on a CTQ, reconstructing it from paper takes days you don't have.
Industry solution
Automotive
Zometric gives automotive component and assembly plants the IATF 16949 toolkit out of the box — live SPC on every CTQ characteristic, AIAG-format MSA and Gauge R&R, PPAP-ready capability evidence, and real-time OEE — so quality is provable to your OEM customers, not reconstructed from paper before an audit.

- Real-timeOEE across lines and plants
Automotive manufacturing is governed by IATF 16949 and the AIAG core tools — SPC, MSA, PPAP, FMEA. OEMs expect every critical-to-quality characteristic to be in statistical control and every gauge to be capable, with traceable evidence on demand. Zometric digitizes that entire stack: control charts and capability indices update in real time as parts are measured, Gauge R&R studies run in AIAG format, lot acceptance follows ANSI Z1.4 switching, and production logs feed OEE automatically. One automotive supplier using Zometric SPC with manual plus automated capture cut PPM by 90% and won new OEM business on the strength of verifiable, digital process control.
The reality on the floor
What slows Automotive quality and uptime
Gauge studies live in disconnected files
MSA and Gauge R&R run once a year in offline templates, calibration due-dates are tracked on whiteboards, and out-of-cal gauges keep measuring parts until someone notices.
Tool wear caught after the scrap is made
Stamping, machining and forging processes drift as tools wear. Without live signals, the drift is found at end-of-shift inspection — after the defective parts are already in the bin.
Downtime and OEE reconstructed after the fact
Production and downtime logged on paper means OEE is a weekly report, not a live number. Root cause is guesswork by the time the data is consolidated.
How Zometric helps
The platform, mapped to Automotive
Each capability is delivered by a module you can adopt on its own and expand from.
Live SPC on every CTQ characteristic
Browser-based Xbar-R, I-MR, P, NP, U, C and Laney charts with all eight Nelson rules and full Cp/Cpk/Pp/Ppk capability — drift is flagged in seconds and routed to the right engineer before the next part is made.
Delivered byIn-Process Quality & SPCAIAG-format MSA and gauge control
Crossed and nested Gauge R&R, Type 1, linearity and bias, and attribute agreement in AIAG format, plus a gauge register with automatic calibration scheduling and certificate management.
Delivered byGauge & MSAStatistically valid lot acceptance
Incoming, in-process and outgoing inspection on ANSI Z1.4 / Z1.9 and IS 2500 with forward-computed Tightened/Normal/Reduced switching — every lot tied to PO, GRN and batch for full traceability.
Delivered byInspectionReal-time OEE and downtime
Automated production logs and live Availability × Performance × Quality, with operator-logged downtime causes and type-based alerts — one auto component maker cut downtime 40% this way.

FAQ
Automotive — frequently asked questions
Does Zometric support the AIAG core tools (SPC, MSA, PPAP)?
Yes. SPC control charts and capability indices follow the AIAG SPC manual, Gauge R&R and MSA studies use AIAG-format crossed and nested designs (plus Type 1, linearity and bias), and the capability six-pack output is built for PPAP submissions. All calculations validate against Minitab and the AIAG references.
Can it connect to PLCs and CMMs on the shopfloor?
Yes. Zometric Edge connects PLCs, SCADA and sensors for automated capture, the Data Extractor watches shared folders for CMM output files, and operators can also enter data manually on any device. The same data model handles all three capture modes.
How does Zometric help us pass an IATF 16949 audit?
Every measurement is timestamped and linked to lot, batch, operator, inspector and gauge, control charts and capability are always current, and gauge calibration status is tracked with alerts. Audit evidence is queried on demand instead of reconstructed from paper.
Can we start with just SPC and add modules later?
Yes. Zometric is modular — most automotive suppliers start with In-Process Quality & SPC or Gauge Management, then add Inspection and Production Management on the same data backbone as they expand.
