Auto suppliers: Why take our Working Relations Index® survey?

May 31, 2022 / 2 min read

Your OEM relationships have a direct influence on orders, top-line revenue growth, costs of doing business, and your ultimate return on investment. Ever wish you could share candid feedback with your customers? You can. Here’s how.

Participating in our North American OEM-Supplier Working Relations Index® (WRI®) study helps lessen that illusion and can significantly improve interactions among you, your customer, and your respective internal functional groups. Participation in the WRI® survey directly influences top-line revenue growth, the cost of doing business with specific customers, and your ultimate return on investment.

Participating in a WRI® study allows you to contribute your feedback — good and bad — anonymously to your customers. Most OEMs within the North American automotive industry participate in the study and are eager to receive detailed results on their performance. The response rate is high: 2022 participation drew in over 670 executives from over 430 suppliers. This enables an accurate representation of an OEM’s supply base, right down to detailed analyses of purchasing groups within each OEM.

The high-response rate also means that results — good and bad — can’t be refuted as a “one-off” or unique to a particular company or buyer/salesperson relationship. Contributing to a WRI® study assures the data is robust enough to be taken seriously by OEM leadership and the industry overall.

The Plante Moran WRI® is based on three principles:

Participating in a WRI® study also offers opportunities to provide input on customer actions implemented by purchasing groups, which may have been driven by other business functions, such as contractual terms and conditions, payment timeliness, and warranty and other chargeback systems. Sharing your feedback through the WRI® study helps your customers’ purchasing groups effect change within their own companies.

OEMs use WRI® data to:

Suppliers use WRI® data to:

The online survey tool is designed to be as convenient as possible and, while the time commitment isn’t inconsequential, you don’t have to complete the survey in one sitting. You can save, stop, and resume your survey without losing any of your data. And it’s not necessary to have all the answers — you can consult with colleagues in your area and throughout your company.
