I attended Zinovy Royzen's Advanced Practice TRIZ Course in 2007 after having been a TRIZ practitioner and instructor at Kodak for about 10 years. As I expected, Mr. Royzen provided us with problems and guidance that allowed us to sharpen our skills, especially in the use of ARIZ — the most powerful of all the TRIZ heuristics.
I learned and applied many practical problem-solving techniques that I will never forget thanks to Mr. Royzen's practice problems. Since returning to my job, I find that I utilize TRIZ and ARIZ with much greater confidence, allowing me and my team to solve difficult problems in advanced product development. I highly recommend that anyone experienced with TRIZ who wants to take their TRIZ expertise to the next level attend Mr. Royzen's excellent Advanced Practice course.
