Hey everyone, welcome to this lecture. This tool gain chigan boo is a simple, yet powerful tool. I'm now going to share a story of Toyota Motor Company's revised minivan called sienna. I have extracted this excerpt from the famous book the Toyota way written by Jeffrey K. liker. By the end of the story, I bet you will completely understand why Toyota considers gain chigan boo as one of the most important tool in the Toyota Production System. Let's begin.

The 2004 Sienna is what Toyota considers a major redesign a new and improved version of its highly ranked minivan. Toyota engineered it to be a bigger, faster, smoother, quieter and about thousand dollars cheaper car Toyota also designed in many small, but important enhancements that make life easier for the North American driver. Many of these enhancements were the result of gain chigan bootsy. The chief engineer job of developing the Sienna was assigned to Yuji Yokoyama. The primary markets are the US and Canada with some sales in Mexico. Yo Korea had worked on Japanese and European projects, but never a North American vehicle.

He had seen various parts of North America, but not specifically with the eyes of a chief engineer, developing a vehicle for North America. So he failed, that he did not really understand the North American market. Other managers may have hit the books on the marketing data. But that is only one thing you do at Toyota Yokoyama went to his director and requested he be permitted to make a trip. He said, I want to drive all 50 states and all 13 provinces and territories in Canada and all parts of Mexico. Yokota achieved his goal of driving in every single US state, including Alaska, and Hawaii, and every part of Canada as well as Mexico.

In most cases, they were able to rent a Toyota Sienna looking for ways to improve it. As a result, he made many design changes. That would make no sense to a Japanese engineer living in Japan. For example, the roads in Canada have a higher crown than in America bowed up in the middle. Perhaps because of the amount of snow they get. They learned by driving in Canada that Controlling the drift of the minivan is very important when driving on a bridge over the Mississippi River, a gust of wind blew him very hard, and eukarya realized that side wind stability was very important.

Driving through the cross wings of Ontario, he was alarmed how easy it was for trucks to blow the minivan aside. If you drive any place with a crosswind, the newer Sienna is much better. When he was driving the narrow streets of Santa fi Yokoi found it hard to turn the corner with the previous Sienna and improve the turning radius by three feet. This is a huge accomplishment since the new version is also significantly bigger. By practically living in the Sienna for all these riving trips to Korea learned the value of cupholders in Japan, distances are usually shorter. You may buy a can of juice, but it is more common in the culture to drink this outside of the car.

In America on a long trip, he learned it was common for one person to have one half empty cup of coffee or a bottle of water and one full one. You don't want to wait until you stop and have already run out. Therefore, you really need it two cupholders per person, or even three if a person wants a cup of coffee, plus two bottles of water. There are 14 sturdy cup and bottle holders in the Sienna. And there are numerous compartments and pockets for those long trips as well. Jojo also noted the American custom of eating in vehicles rather than taking the time to stop and eat In Japan, it is very uncommon to eat in the car, partly because the roads are narrower, and trucks wind in and out.

So you need to focus on the road and periodically take a break from the stress. The luxurious American highways lead to more relaxed driving using cruise control. So he learned the value of having a place for hamburgers and fries by putting up a flip tray accessible from the drivers position. This option had been previously adopted by Toyota minivans in Japan, but is even more useful for the North American market. The original concept for a longer minivan also came from gain chigan butsu Dr. Akiko Seidel, who was responsible for all of r&d for Toyota globally, believed in the design philosophy that smallest smart The philosophy is to adopt the smallest possible exterior to minimize the weight of the vehicle while achieving the appropriate interior volume. However, during a visit to the Toyota Technical Center in Ann Arbor, he took a trip to Home Depot.

He just stood in the parking lot and watched what psychos saw were Americans buying large things like a four by eight plywood and putting them into the back of their pickup trucks and Honda Reese's. Back at the Technical Center, he also saw how a sheet of plywood fit into the Honda Odyssey, but not the previous generation Sienna Mr. Psycho approved the size to accommodate the four by eight plywood for the new Sienna on the spot. Well, with that we come to the end of this lecture. It is now time to understand the steps involved in implementing NT in Woods
