Cybernetics and Systems Thinking

The Science of Control

Norbert Wiener (“Cybernetics,” 1948) created the science of control and communication in animals and machines. The key idea: feedback is a universal mechanism of management. Thermostat, neuron, economy, society—all are governed through feedback: the system receives information about the outcome and adjusts its actions.

This is a revolutionary generalization: one conceptual scheme describes control mechanisms in biology, technology, and social systems. Cybernetics became the precursor of systems thinking, information theory, cognitive science, and artificial intelligence.

“Information” as a fundamental category: not matter and not energy, but a measure of the reduction of uncertainty. Claude Shannon (“A Mathematical Theory of Communication,” 1948) formalized the concept of information through the “bit” and entropy. This laid the foundation for coding theory, cryptography, and data compression.

Systems Thinking in Management

Jay Forrester applied systems thinking to industrial management and cities. His student Dennis Meadows applied it to global ecology (“The Limits to Growth,” 1972, commissioned by the Club of Rome). The result: a computer model of the world system predicted collapse if growth trends persisted.

Peter Senge (“The Fifth Discipline,” 1990) brought systems thinking into management: “learning organizations” must understand systemic structures, not just linear cause-and-effect relationships. “Everyone thinks the problem was created by someone else”—a standard illusion of linear thinking in systemic situations.

Question for reflection: Name a system in your work where improvement of one part worsens another (systemic feedback). How can one redesign the system, rather than combat the symptoms?
