In Intr troductio tion How do you approach in the technical field without the current experience when it will be necessary to develop the product with high competitive edge in a short term? I will introduce the approach of the product development to make good use of TRIZ, Taguchi method, and CAE in the technical field 'All-Japan manufacturing ＴＲＩＺ Koma great war' that was newly born.

What at is is th the all all-Jap apan an man manufac factu turin ring Koma ma gre reat at war? war? ■ What is the Koma great war? It is a rally (bringing together Koma that small and medium manufacturers in the whole country are bet the boast of its company and made, and the fight by the one to one). Manufacturing seriously designs small Koma, and everything is poured and the technology that its company can have with a professional machine is made. A professional technique is fatty soaked of the ring on each other. ■ What rule? Having kept turning longer than other party's Koma wins. It is defeated besides the ring when going out. Game end at two successive victories The victor can get loser's Koma. (It is a content total removing of booty till then. ) The １１ th Japan TRIZ Symposium 2015.9.4 5
