CORE DEFINITION

General Systemantics (retitled to Systemantics in its second edition and The Systems Bible in its third) is a systems engineering treatise by John Gall in which he offers practical principles of systems design based on experience and anecdotes.

Gall's Systemantics studies why systems often behave contrary to their design goals. Core axioms: systems often do the opposite of their goals; complex systems can only evolve from simple systems that work; designing complex systems from scratch is doomed to fail. Systems have 'actual behavior' rather than just 'declared function'.

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

First build a minimal viable simple system
let it evolve in a real environment rather than top-down one-shot design
monitor the system's actual behavior (often contrary to declared function)
be sensitive to small failures and iterate
be wary of counterintuitive failures brought by scale.
