Asking if anything has changed (here), @maison_faim , is a tougher question than you think.
In Toronto, we are in year 2 of an espoused 10-year project on Systems Changes http://systemschanges.com/online/ .
We are converging on 5 questions along 5 philosophies (phenomenology, ontology, epistemology, phronesis, techne).
This is extending systems thinking for an audience that talks "systems change", but doesn't have a firm foundation.
Lots more work to do.
