Motor Vehicle Electrical and Electronic Equipment Manufacturing

NAICS 336320 · Transportation Equipment Manufacturing6 · SBA size standard: 1,000 employees

This industry manufactures electrical and electronic equipment for motor vehicles such as wiring harnesses, instrument clusters, sensors, lighting control modules, power distribution centers and battery management systems. Orders come from OEMs and tier-one suppliers with strict specifications, revision levels and delivery windows. Specialists convert purchase orders into production schedules, exploded bills of materials, procurement lists and test plans while tracking engineering change orders, component traceability and PPAP documentation. The production manager and engineers retain authority over process validation, quality sign-off and any deviation from customer requirements.

Workflows

Customer order and specification intake

Starts when: Receipt of purchase order, forecast release or engineering change notice from OEM

  1. Parse the PO for part number, revision level, quantity, delivery date and special instructions
  2. Compare against current approved drawing and BOM revision
  3. Flag any discrepancies or new requirements for engineering review
  4. Create a production order task with linked specifications and customer requirements
  5. Acknowledge receipt and confirm delivery window
  6. Attach all customer-specific labeling and packaging instructions

Watch for: Every part number must match the exact customer revision; New or revised drawings trigger immediate PPAP or deviation workflow
