Organizations as complex adaptive systems, not machines. Feedback loops. Emergence. Variety engineering: only variety can absorb variety. Non-linear dynamics. The most mathematically sophisticated cluster of management theory.
Fleet: THE most directly applicable cluster. VSM = fleet architecture. Cynefin = SOSTLE modes. TOC = LAAM constraint gate. Antifragile = baobab reserve-based persistence. Ashby's Law = fleet variety design.
