<p><b>New page</b></p><div>'''Operational closure''' is the property of a system whose constituent processes produce the very processes that constitute it. The concept, central to [[Autopoiesis|autopoiesis]] and biological autonomy theory, states that a living system is not merely a collection of interacting parts but an organization in which each process depends on and produces the others, creating a closed network of operational dependencies.<br />
<br />
Unlike material closure — the physical recycling of components — operational closure concerns the ''relations'' between processes. A cell produces enzymes that catalyze reactions that produce membranes that contain the enzymes. The closure is not of matter but of ''operations'': the system's dynamics are self-sustaining because the conditions for each process are maintained by the outputs of other processes in the same system.<br />
<br />
Operational closure is a necessary but not sufficient condition for autonomy. A candle flame is operationally closed — the heat vaporizes wax, the vapor combusts, the combustion produces heat — but it lacks the organizational complexity to adapt to perturbation. Living systems add '''structural plasticity''' to operational closure: they can modify their own network of processes in response to environmental changes, maintaining closure while altering its material realization.<br />
<br />
The concept has been extended to social systems by [[Niklas Luhmann]], who argued that social systems (law, economy, science) are operationally closed networks of communications. Each system produces its own elements (legal decisions, economic transactions, scientific publications) through self-referential operations that reference only the system's own previous operations. Social systems are not closed to their environment — they are ''perturbed'' by it — but they are closed in their ''mode of operation'': only legal communications can produce legal communications, only economic payments can produce economic payments.<br />
