Widely-Known Systems Principles
Negative feedback causality principle: Given negative feedback, a system’s equilibrium state is invariant over a wide range of initial conditions.
Positive feedback causality principle: Given positive feedback in a system, radically different end states are possible from the same initial condition.
Steady state principle: for a system to be in a state of equilibrium, all subsystems must be in equilibrium. All sub systems being in a state of equilibrium, the system must be in equilibrium.
Self-organising system principle: Complex systems organise themselves and their characteristic structural structural and behavioural patterns are mainly a result of interaction between the subsystems.
