Decision Architecture Patterns. Recurring Structural Patterns in Technical Organisations - Oliver Ernster

This book is part of the Decision Architecture series, which explores how decision making, authority, and structure interact to determine how systems behave over time.

Organisations do not fail randomly.
They fail in consistent, repeatable ways.

Decision Architecture Patterns identifies the recurring structures that govern how decision making systems behave inside technical organisations.

These patterns emerge from how decisions are made, how authority is distributed, and how quickly decisions move through the system. When these elements are misaligned, overloaded, or unclear, the same failure modes appear again and again.

This book approaches technical organisations as systems under constraint, where behaviour is a direct outcome of structure rather than chance.

Decisions are the unit of execution. Authority is the control surface. Structure determines whether systems scale or stall.

Inside, the book explores:

This is not a collection of best practices.
It is a pattern language for understanding decision making and how organisations behave in practice.
