Especially Systems Theory in its second manifestation (Maturana, Luhmann, von Förster, Glasersfeld - and Ackoff) is extremely powerful, deep and, reasons beyond me, totally overlooked.
Have to say tho, most MBA‘s I encountered sadly never ever heard of Cybernetics or Systems Theory. :-(
This is all not 'new' in the literal sense. Luhmann died in the late 90s. I tried to come up with a spot-on-book of Luhmann, but that lead to nothing. It's all spread out (papers and books) as far as I know. There is a (transcribed) lecture given in 1992, which may come close, but I couldn't find a translated version of it.
One of the parts which hit home for me was the introduction of a differenciated form of distinctiveness, in turn partly enabled by the introduction of an observer, and observation in general. Heinz von Foerster gave an often cited sentence which I think fits the part, albeit Luhmann gurus will probably moan my simplification : "Objectivity is the delusion that observations could be made without an observer."
Apart from that, sorry for not being more helpful here.
