Introduction

3 / 20

Our company introduces TRIZ and ten years have passed. The in-house promotion activity of
the TRIZ use of ten years was the one through practice. It has kept first applying TRIZ toactual subject, it learning to the success and the failure, and it groping for the approach andthe tool of new TRIZ use.
It looks back on the promotion activity for ten years, and this time, what problem exists, and it
reports sometimes what improvement on you have tried. Additionally, it introduces the groping
case with a new tool.
It would be greatly appreciated if the opinion it becomes your reference and without thediffidence could be sent.

20 / 20③ Summary
1. There can variously be method of ..TRIZ.. promoting in-house.
Running promotion is the one shape as for practice.
(Practice: First of all, TRIZ is applied to actual subject.
A small success and the failure are piled and it learns.
It gropes for a new approach and the tool. )2. The purpose of in-house promotion is a solution from the development of
TRIZ.
3. It deals with various problems for the solution.
Various approaches and tools are necessary.
The combination to which not only TRIZ but also
another technique is taken is effective.
- Practice and the education are both circles of the car. It is in-house propeller's role to offer both chances.
- It is necessary to establish the effect and the evaluation method of the TRIZ use told by the third party.
