Trazabilidad en secuencia justa que elevó a OEE en 9 puntos.
A German OEM body-shop was losing time to sequence errors and had no audit-grade genealogy for IATF 16949 .
A qué se enfrentaban.
Los errores de secuencia provocaron reestructuraciones
Trabajos mal secuenciados provocaron reestructuraciones y paradas de líneas no planificadas.
No hay genealogía de grado auditivo
La trazabilidad de IATF 16949 no pudo reconstruirse rápidamente para auditoría.
Control manual de herramientas
El control con herramientas de par era manual y no estaba vinculado al vehículo.
Identidad del cliente reservada por confidencialidad. Las cifras reflejan resultados de despliegues RTLS/RFID comparables; sus propios números dependen del caso de uso, el entorno y la ejecución.
Neutral respecto al proveedor, orientado al resultado.
We combined UWB tool control with Passive RFID just-in-sequence traceability, integrated to Siemens Opcenter MES , binding every torque event to the VIN.
Lo que entregamos.
- Trazabilidad en proceso justo en secuencia en grado de auditoría IATF 16949
- UWB -tagged torque tools bound to the VIN
- Integración Siemens Opcenter MES
El resultado que vio la junta.
La pila detrás
Programme pattern for this vertical
JIS programmes verify sequence integrity from supplier through yard to station consume. UHF RFID portals plus selective RTLS on tuggers/AGVs is a common pattern under IATF and OEM CSRs.
Genealogy queries and containment speed are the design north star.
Governance, risk and what we refuse to claim
Composite example only. Your payback depends on adoption, integration quality and exception labour — not tag unit cost. Named references under NDA on engagement.
We challenge any vendor who asks you to accept demo-day averages as production truth.
Implementation sequence and change management
Map CSR strictest requirements; instrument supplier-to-station handoffs; MES as SOR; prove containment query in pilot. Include yard metal in RF design.
KPIs: sequence accuracy, line-stop minutes, containment elapsed time. Keep 2D fallback. Challenge 'IATF compliant' logos without genealogy demo on your part numbers.
Buyer checklist, vendor challenges and engagement shape
For JIS, make containment query speed and CSR mapping gate criteria equal to portal read rate.
Buyer checklist before you sign: (1) written system of record for events; (2) acceptance tests with 95th-percentile performance under real interference; (3) integration owner named in IT/OT; (4) privacy or labour consultation path if people are tagged; (5) cybersecurity zoning sketch; (6) five-year TCO including batteries, spares, recalibration and SLA escalations; (7) exit/export terms so you are not hostage to a cloud tenant; (8) a pilot that can fail without political punishment.
Vendor claims to challenge in this pattern: brochure accuracy without production load; 'compliance included' without artefacts; ROI that assumes perfect adoption in 30 days; references that cannot be called under NDA; install partners who have never worked your vertical's overlays; shared support accounts; and any design that dumps locating onto a flat plant or clinical VLAN.
How TRACIO typically engages: stage-1 architecture and measurement design; vendor-neutral shortlist and RFP language; pilot acceptance criteria; then optional implementation oversight or programme rescue if a prior pilot stalled. We stay independent of hardware margin. Composite pages like this one exist so you can prepare the workshop — your numbers replace every planning band when we model payback.
Risk register themes that recur: mute fatigue on alerts; shadow spreadsheets reappearing beside the platform; battery logistics understaffed; master data too weak to support identity; works-council or IG review starting too late; and success declared on demo day before night-shift reality.
Document baseline windows explicitly: what you measured, for how long, which shifts, and what you excluded. Investment committees and auditors both punish fuzzy before/after stories. If your baseline is weak, spend two to four weeks fixing measurement before ordering anchors or portals. That discipline is cheaper than a stranded deployment and is the difference between a locating programme and a technology souvenir.
