Dear Dr. Karasik:

Thank you for facing actual tsunami problem and now positive attitude towards Altshuller's Matrix.

I'd like to point that Cost is not technical but economical parameter and it used actively in Value Engineering. I'd like to point also that Safety as Matrix parameter was described in Savransky book.

It would be nice to see at least 0.1% references on "after analyzing 100,000 innovative solutions that resolve contradictions between various costs" - now it looks like next TRIZ hipe a'la "we studied 2 millions patents" ..... Did you have a meter that stopped you exactly after solution No 100,000 or where no 100001 solution in the world?

Sincerely,

Juj Chan Hyjun

Dear Mr. Hyjun,

thank you for your letter. I appreciate your humor.

Regarding your claim that "Cost" is economical parameter, I would like to notice that there is no clear cut border between economical and technical parameters. For example, productivity, one may argue, is also "economical" parameter. Nevertheless, it is on the list of Altshuller parameters.

Sincerely,

Yevgeny Karasik

Dear Dr. Karasik:

RE: "For example, productivity, one may argue, is also "economical" parameter."

Yes, sometimes, but it is almost always technical (e.g. in mechanical watches we don't care about productivity /rotation per hour/ of each part).

Dear Mr. Hyjun,

If a parameter seems to be "economical", it does not justify its exclusion. If "technical" parameter (e.g. safety) contradicts to "economical" parameter (e.g. cost), then, what, there is no contradiction ? Or we do not have to resolve this contradiction ? Or what ?

Who told that only "technical" parameters have to be included ? Why "cost" is used in other parts of TRIZ, e.g. in the definition of the degree of ideality (cost of useful effects / cost of harmful effects), and should not be used in contradiction matrix ?

To be logical to the end, ALL parameters that may contradict to the "technical" ones have to be included.

Sincerely,

Yevgeny Karasik
