History of the North American Automotive OEM-Supplier Working Relations Index® Study
The WRI® Study is rooted in academia and continues to follow the same quality standards today. The study began in the early 2000s when Professor John Henke sought to independently survey suppliers and discover their perceptions of working with their North American OEM customers and what was driving these perceptions. The Henke survey continued on with Planning Perspectives, Inc. (PPI), which joined Plante Moran in January 2019. Our manufacturing and automotive teams have experience working with both suppliers and OEMs for over 90 years and provide comprehensive audit, tax, and consulting services to help companies succeed.
