Counterintuitive Behavior of Social Systems
by Jay W. Forrester · MIT OpenCourseWare
Forrester's 1971 essay, drawn from urban dynamics modeling, argues that social systems built from multiple nonlinear feedback loops defeat intuition, so well-meant policies treat symptoms and often worsen underlying problems. A PDF that explains why simulation models outperform mental models in policy design.

Mastering Systems Thinking in Practice
An eight-week Open University course in systems practice: drawing rich pictures and influence diagrams, choosing system boundaries, reconciling conflicting stakeholder perspectives, and applying Soft Systems Methodology to messy organisational situations that resist quantitative modelling.
The Fifth Discipline: The Art & Practice of The Learning Organization (Revised Edition)
Senge's revised edition applies feedback thinking to organisations and sets out the system archetypes - limits to growth, shifting the burden, tragedy of the commons, eroding goals - that explain why the same dysfunctions keep recurring in teams and companies. This book spawned an enormous amount of derivative management fluff, but the archetype chapters themselves are structural.
If Russ Ackoff had given a TED Talk...
A twelve-minute 1994 talk in which Ackoff states the distinction underneath all systems thinking: a system's essential properties belong to the whole, not its parts, so optimising every part separately can reliably degrade the whole. The highest ratio of insight-to-minutes on this topic anywhere: it delivers the whole-versus-parts argument in twelve minutes, which most management books fail to deliver in three hundred pages.
Leverage Points: Places to Intervene in a System
Meadows ranks twelve places to intervene in a system, from tweaking parameters and buffer sizes up through feedback loops and rules to system goals, paradigms, and the power to transcend paradigms - a map for judging which interventions actually matter. Its ideas are so widely diluted that finding the original matters: this is the piece the Wikipedia 'Twelve leverage points' article and hundreds of consultant blog posts derive from. Advanced because the ranking only makes sense once feedback-loop vocabulary is in place.
