buttons.Editor's Note (Toru Nakagawa, Sept. 10, 2002; Translated into English on Mar. 7, 2003)
This document is a list of the Trends of System Evolution, according to Darrell Mann's new TRIZ Textbook. This document was composed during the process of reorganizing TRIZ Solution Generation Methods into those of USIT and is now posted here as a basic document for making links among various methods and documents of TRIZ and USIT.The Original Reference is:
"Hands-On Systematic Innovation", Darrell Mann, CREAX Press, (May 2002).Mann's list is easy to understand and contain some new trend items and various insights. For the ease of reference the trends are numbered as they appear in Mann's textbook.
Cross-references to USIT Solution Generation Methods are shown in a form like: [USIT 1a]. See more detail in the document of "USIT Solution Generation Methods (Extended Version)".
Refer to the list of various TRIZ tools in the parent page.
Editor's Note (Toru Nakagawa, Dec. 19, 2012)
TRIZ 'Trends of System Evolution' were developed originally by Mr. Genrich Altshuller
(Ref. G.S. Altshuller: "Creatrivity as an Exact Science!", Gordon & Breach Science Publishing, NewYork, 1984;
G.S. Altshuller: "To Find an Idea", Nauka, Novosibirsk, 1986 (in Russian).
They are referred here in the form of Mann's textbook which is more commonly available in Japan both in English and in Japanese.
I am happy to upload this page again under the permissions by Mrs. Larisa Komarcheva & Ms. Yuna Komarcheva and by Mr. Darrell Mann.
