The interest in TRIZ creates a few versions of "Simplified TRIZ". The authors of these versions usually claim that it is more easy to learn such approach to compare with classical TRIZ. Perhaps, they are right, but as a result students cannot resolve many of real problems.
Some companies advertise their version of methods that they claim beyond TRIZ. In reality this no more than a marketing trick.
Unfortunately, there are a few attempts to steal TRIZ ideas without
reference to their source. Shame on this!
