Modern systems — clinical, ecological, economic, and infrastructural — often fail not because individual components break, but because the relational structures that sustain them degrade. This book develops a practical framework for understanding, detecting, and navigating such failures.
Building on a minimal relational grammar of seven functional roles — Constraint, Margin, State, Disturbance, Perception, Regulation, and Options — and their organization into triadic closure, the work shows that viability depends on maintaining coherence across these interdependent relations. When this coherence is disrupted, systems exhibit characteristic early warning signals: path dependence, cross-channel divergence, increasing variability, and delayed recovery.
The book advances a diagnostic pipeline linking abstract structure to observable indicators, enabling practitioners to infer hidden breakdowns before collapse occurs. It further demonstrates that conventional control-based interventions often exacerbate instability by acting on observable projections rather than underlying structure.
In response, the text develops a mode of action based on navigation rather than control — preserving margin, maintaining options, and aligning interventions with system dynamics. Through applications in medicine, ecology, economics, and infrastructure, the framework is translated into operational practice.
This work bridges formal relational insight and real-world decision-making, offering a unified language for diagnosing and sustaining viability across complex systems.
