Taiichi Ohno, Toyota’s chief process engineer, added many of the tools and detailed production processes to Kiichiro Toyoda’s vision, and he understood that what would soon become TPS could be applied more broadly than just to manufacturing. In his book Toyota Production System: Beyond Large-Scale Production (1988, xv), he states:
"The Toyota production system, however, is not just a production system. I am confident it will reveal its strength as a management system adapted to today’s era of global markets and high level computerized information systems."
Together, Ohno and Toyoda ushered the Toyota Group into an era of world-class production.
