Editor's Note (Toru Nakagawa, Sept. 19, 2011)

This paper was presented 10 days ago as a Special-Interest Lecture of Seminar (A) at the Seventh TRIZ Symposium in Japan, 2011.  Even though the lecture was givne in Japanese only, I have prepared the slides in English as well.  In the digital version of the Symposium Proceedings/Materials, both Japanese and English slides were stored.  For wider circulation, I am posting the lecture slides publicly here both in Japanese and in English.

The present lecture was given for beginners and experienced people in TRIZ/USIT.  The lecture was given 70 minutes including Q&A.  Thus I could talk on USIT in its full length.  It is quite fortunate for me to have the chance of preparing the English slides of the full-length lecture on USIT; in spite of various chances of talking/writing on USIT in Japanese, I had less opportunities to explain about USIT in English.  I wish the present lecture of some help for you to understand USIT and to reconsider about TRIZ.  . 


[1] Abstract

USIT: A New Paradigm for Creative Problem Solving
-- Its Concept and usage --

Toru Nakagawa (Osaka Gakuin University, Japan)


USIT (Unified Structured Inventive Thinking) is a unified process for creative problem solving, and was developed by Ed Sickafus (USA) in 1995 under the influence of TRIZ and Israeli SIT. We have introduced it into Japan since 1999 as a practical process for applying TRIZ easily and have extended it further. We have reorganized all the solution generation methods in TRIZ into a new system of USIT Operators. In 2004 when we represented the USIT way of thinking with a data-flow diagram in place of an ordinary flowchart, we obtained the Six-box Scheme in contrast to the Four-box Scheme well-known in TRIZ and in science and technology.

The Six-box Scheme has been found to be significant as a 'New Paradigm for Creative Problem Solving'. Using a standard method, we obtain the understanding of the present system in terms of Objects, Attributes, Function, Time and Space, and also the understanding of the ideal system. Then we apply the USIT Operators to obtain some core ideas for our new system, and we further build up new solution concepts on the basis of our capability in the applied fields. USIT provides us with a concrete, practical process for achieving the problem solving along the Six-box Scheme.

In the lecture I will talk about the concepts and usage of USIT, together with some examples.
