Many ideas？

Many ideas have been wasted. MOTTAINAI！
However, there are some way to utilize those ideas.

TRIZ symposium 2012 Paper1

The outline of presentation
When engineers utilize TRIZ for devising solutions of problems orinventing with a team, they tend to aim at many ideas come from abrainstorming. They study various aspects with all the members and makevarious suggestions, then they would get contentment or accomplishment
at they reached to have certain amount of ideas on the table. After that,they prioritize those ideas from the point of view of ROI or compatibilityof existing technologies. As the result, they conclude to choose some ofthe ideas.
On the other hand, the many ideas which were not chosen fade away.
However, there are some ways to utilize those ideas which were notchosen.
In this presentation, we propose a practical approach using TRIZ method
for convergence to maximize various suggestions and ideas.

６．Summary
We propose practical convergence approaches, which
includes TRIZ thinking process, to aim for utilizing all ideas
or proposals.
The common thinking approach is;－ Screening ideas－ Integrating ideas－ Shape into a plan
We recommend to switch the process to gestating ideas
based on its feature from selecting prior ideas.
We would like to add proposals to Two-dimensional map,and practice thinking process for prediction a change to S
curve from finding major contradiction.
