Well known is that Altshuller steadily tried to improve TRIZ with new tools and methods and each time he thought the last one was the best. To me, it's a rather a sign of enthousiasm than of reject. Today, we may consider that the link between problem formulation and heuristics is a unique feature of the TRIZ approach, which was established first with the matrix (than with the SU-Field method …). Quite early, the following critics were discussed: need of update, difficulty to identify and select the relevant parameters of a technical contradiction, high abstraction of some principles, lack of accuracy, aso… to name a few! Does it mean the original genius of the matrix is just vanished! I don't think so. Some progress was registered on this front with “Matrix 2003, Updating the TRIZ Contradiction Matrix”, a stepwise consideration of the principles, links between principles and technics/effects…It means TRIZ is not embedded in granit and may evolve too, without loosing the originality of the approach.
