Our Story

In the 1960's, Mr. Herbert Hummel was hired away from Volkswagen by Toyota and promptly sent to Japan to learn the now "world renowned" Toyota Production System. Mr. Hummel studied in Japan over 2 years with Mr. Taiichi Ohno and Mr. Shigeo Shingo, among others, and was appointed the U.S. Director for establishing an auto dealer presence in the United States. Toyota challenged Mr. Hummel to use the TQM methodologies he learned in Japan to streamline dealership development and creation and to use that process to help further establish Toyota within their new market. Under Herbert's leadership a two year dealership set up process was quickly turned into an efficient and effective three month cycle with the implementation of TQM methodology.

This initial success formed the groundwork for IQC.
