"Historically, each TRIZ tool was developed (and could be used) independently for problem solving. That is why each tool had its own mini-algorithm. Trials to bring them to work together (e.g., with ARIZ) were not enough, in my opinion.
This work is a revision of the main TRIZ tools so that they work together as parts of the same system. The presented algorithm consists of three main parts.
Describe the situation in a simple and understandable way, using words and expressions that will be clear to an inexperienced person." Match the first letter of the description with one of the following symbols:
A, B, C, D, E, F, G, H, I, J K, L, M, N, O, P, Q, R, S, T, U, V, X, Y, Z, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0.
If the description starts with a vowel, use those of 40 Principles which have odd numbers. Otherwise use principles with even numbers. Good luck !
What? Absurd ? Then why is the problem solving algorithm by Gregory Frenklach published in the June issue of TRIZ-journal any better ?
The only difference is that it selects Principles not on the first letter basis but according to a more complex procedure. But the complexity of a procedure does not imply neither that it is correct nor that it is founded. Con artists always exploit this common error of thinking when everything complex and convoluted adorned with schemes and tables is perceived as something sound and scholarly.
Besides TRIZ tools are not confined to 40 Principles only and TRIZ tool search algorithm has to search amongst other tools such as SuFiled analysis and the Standard solutions too. Frenklach did not make good on his promise given in introduction.
