The North American Automotive OEM-Supplier Working Relations Index® (WRI®) Study is a comprehensive annual survey that examines the working relations between Tier 1 suppliers and their North American-based OEM customers from the suppliers’ perspective. Using our proprietary WRI® methodology, the qualitative working relations of each OEM are quantitatively determined and ranked on a 500-point scale.
We invite suppliers to share their firm’s day-to-day working experiences with the OEM(s) for whom they have commercial responsibility through this confidential study. The WRI® study is valued by OEM leadership and the automotive industry overall. This honest supplier feedback provides actionable information and can help improve timeliness, cost, and quality of every interaction between OEMs and their supply base(s).
