Congratulation!!! Mr. Charlie Lutaud from France finished 1st level TRIZ-training

This Knowledge is wonderful! It's the real answer of the question: How to invent?
Nowadays, the engineering complexity has made engineers too specialized to think about solutions from another discipline. TRIZ resolve this problem, that's why, for me, it is the most powerful tool for engineering, each engineer would have to know it, and all technical systems would be improved.
IID is brilliant for TRIZ training, a progressive learning for getting pleasure in resolving problems, thanks a lot!
