Introduction

3 / 28

Our company introduces TRIZ and ten years or more have passed. It can be said that TRIZ
in-house promotion of ten years came at the practice center. What is practice? TRIZ isapplied to the problem of a first of all actual business. And, the utility is acknowledged, andthe promotion method of increasing "Repeat customer" and "New user". Therefore, many ofpractitioners are TRIZ beginners.
The motive for which the beginner tries to use TRIZ is various. When the tool and theapproach are selected by the propeller, it is necessary to match it to the beginner needs morethan matching it to the theme.
"Case that goes well" and "Case that doesn't go well" are analyzed in the promotion activityof ten years and the encountered various scenes are analyzed. And, to answer the beginnerneeds, "How is the beginner led to TRIZ?" is considered.

3. This Point under Discussion（１）7 / 28① It is not enough only by the tool and the approach matched to the theme.
Case that doesn't go well often experienced

User's impression after it acts
A lot of time has been taken in the problem analysis though a lot of ideas were
expected to be shown.
It was disappointed in "Analysis why why" in which the first work was known
well though many had been expected of the new method named TRIZ.

Though the charm was felt in the idea of contradiction of TRIZ、 when turning
around、It is made sure of what and not made sure whether contradiction was
really canceled because of contradiction.
It worked as said about the propeller. What you do now has not been understoodeasily from what being aimed.

It did not go well.
Many of case

7. Summary

28 / 28

1. "How is the beginner led to TRIZ?" is an important point in TRIZ promotion.
2. The mismatch of the selection of "Beginner needs" and "Tool/approach" isoften experienced in the place of practice.
An in-house propeller should be sensitive to the beginner needs.
3. The beginner needs are various.
Tool/approach selection matched to each beginner needs is necessary.
4. It is necessary to analyze a variety of beginner needs, and it makes
to the pattern and to understand the tendency.
It classified it from the experience of practice into three beginner needs
and two aims.
5. It proposed tool/approach according to the classification of the beginner needs.
It wishes to become some references.
― Notice inevitably by the process of analyzing the beginner needs. －◆ Not only a technical result but also engineer's satisfaction rating relates closely
to the success in the TRIZ practice.
◆ It is a couching from the consulting to raise engineer's satisfaction rating.
