Auto supplier working relations: Top takeaways from the 2021 WRI ® Study

Supplier relationships impact OEMs’ bottom lines. The annual Plante Moran Working Relations Index® Study measures the responses of over 700 suppliers on the quality of these relationships, and the 2021 WRI® Study results are in. We share key findings and what they mean, including:

  • How OEM-supplier relationships influence competitiveness.
  • How companies can help future-proof their business with respect to resource constraints, tech commercialization, the EV transition, and cost competitiveness.
  • Communication in the automotive customer-supplier equation.

Learn how suppliers rank their interactions with six OEMs across four indices and see how companies that will thrive in the future need to leverage trust — rather than merely per-piece price — for competitive advantage.
