The Wikipedia article has no criticism section.<p>It might be great as taxonomy of problem solutions, but there is no reliable evidence that it works as a methodology. Reducing research activity to a bunch of codified chess-like moves is a huge temptation. However I haven&#x27;t seen its adepts producing any unexpected results (in practice, not on some TRIZ textbook puzzle). The solutions were on par with what you&#x27;d expect from a person of comparable intelligence, experience and education background otherwise.
