The TRIZ theory, a theory of invention as a support to R&D activities; tools and illustrations of its implementation

For almost two decades now, TRIZ (Russian acronym for Theory of Inventive Problem Solving) has been establishing itself as a well-equipped theoretical approach to the search for solution concepts, particularly in industry. To date, a number of assessments of its uses have been carried out, and the results all attest to its potential. However, perceptions of this enigmatic acronym are legion, and its results in business, education and research are often controversial. If there's one article title that sums up this state of affairs, it's the one published in Philippe Beaufils' magazine "Industries et Techniques" in June 2001, where he formulated the following expression: "TRIZ intrigues, disturbs, seduces...".

This article, the second in a series of two, takes a pragmatic look at the content of the TRIZ body of knowledge, in order to give as precise an overview as possible of what it contains.

This article is dedicated to TRIZ tools, and includes a paragraph dedicated to the ARIZ 85C algorithm. It takes up the concepts covered in the first article [AG 5 211] , with a complete and developed example illustrating the main stages in the TRIZ methodological sequence, and a possible way of orchestrating the implementation of the elements covered in the two articles.
