Toyota has taken the Deming methodology of management to heart, and has had worldwide impact with their Toyota Management System, developed in concert with major universities around the world, including Carnegie Mellon, the General Motors Institute, Kings College, Cambridge and Zurich Polytech. Porsche and Harley-Davidson remodeled their processes based on their input.
Toyota took over the somewhat disorganized FBO at Torrance, and using TMS made it efficient and profitable.
They made considerable investments in exotic composite component production, heretofore confined to low production quantity specialty items, like sailplanes, race cars, sporting equipment, etc. They funded research and application studies that simplified the curing and quality control methods, which were bottlenecks. This should benefit the industry as a whole, even though they determined that there was no business future in light, civil aircraft. (IMHO, pilot training, insurance and increase of regulations were major factors.)
