Last year's announcement

•••

••

Attribute analysis and cause functionｰThe entire problem can share
understanding because all project members execute the consequence analysis.
By using Goldfire、 The hint from the knowledge base like the invention
principle etc. supports the idea putting out.
The member's sympathy is obtained for the solution. 。
The member with a shallow experience is connected bottom-up.
Time (training) is necessary for the technique acquisition. The in-house
consultant's (specialist) promotion is preferable.
Results of a machine and an electric electron system device are many. The
improvement (read in a different way) matched to the chemistry or more
system is being examined. 。

It uses it for the improvement
activity of the office.

TRIZ is introduced.

Last year's announcement

Approach in fiscal year 2013•••••

The post that has a device or more and processed process in allcompanies is selected as "Object office".
"Desire" as the post is valued. A strong will of the executive class
was confirmed centering on the top.
Beginning from “QFD" first of all. The extraction and the arrangementof the customer needs are executed centering on the production
department.
Enthusiastic "Theme" (It is said that it was sure to sell if this wasable to be achieved (Will sell it)) was able to hang.
The technique for the problem solving is used. （TRIZ,Taguchi Method…)。

The member understands an individual problem of holding itby ..function.. using the attribute analysis and the cause result
analysis and it uses it as a tool that shares.
Goldfire is used more as a tool of the idea putting out.
Time (training) is necessary for the technique acquisition. The scene
to be used repeatedly is understood and followed.
Avoid the training of a long term, and in pinpoint guidance.
An in-house consultant is effective. It is necessary to promote it.
The improvement (read in a different way) matched to the chemistry or
more system is being examined.
It concentrates on "Spread (well-known) activity" and "Roundsman".
