TRIZ master Victor Fey impressively deals with the complex contents of TRIZ.

For anyone wanting to delve more deeply into the topic of Substance-Field Analysis and ARIZ this is the ideal book. Using numerous examples that he implemented himself, Fey explains the capabilities of these methods. Concentrating on the essentials, he deliberately omits many other methods of the TRIZ arsenal. Containing many exercises, this book is also suitable for self-study.

For me the style of this works conveys a piece of Russian spirit.
