Vester's Sensitivity Model

A comprehensive set of nine tools and associated methods for understanding complex social systems. BrainSite

Fredrick Vester provides a comprhensive set of interconnected methods and tools for understanding complex social systems.

There are nine interacting operations that make up the structure of a cybernetic system:
