About the Book

Complexity is considered by many to be the single most important scientific development since general relativity. Complexity Sciences study systems like cities, weather systems, teams, and organisations,

With users, customers and competitors that are hyperconnected, and with the rate of change of the markets and the technology that is constantly accelerating, understanding Complexity today is more useful than ever.

This book is a catalogue of practices inspired by Complexity thinking, that are useful to navigate the Complexity of everyday software and digital products development, and to learn to dance with a complex system. This book is for everyone working in software and digital products development, and more specifically for leaders, managers, facilitators, and team members.

The practices in this book provide a practical introduction to Complexity thinking and are a stepstone to the theory of Complexity. For those already familiar with the theory of Complexity, the practices in this book suggest ways to put Complexity in action and to live Complexity.

The practices in this book are inspired by the work of Joseph Pelrine, David S. Alberts, Ralph Stacey, and Dave Snowden. This book also contains original contributions from Dean Latchana, Liz Keogh, and the author himself, Luca Minudel. Hopefully, this book will also be an example that inspires other Complexity practitioners to share other practices that could potentially be added to this book.

Note to this 3nd incremental version of the ebook, published in July 2020.

This third version of the catalogue completes Part 1 with 2 additional practices. It extends the initial paragraph of Part 1 with important clarifications, and ends Part 1 with the conclusions.

Once every week or two, a new draft of the catalogue will be published with two additional practices. The final version of this catalogue will contain between 14 and 16 practices.
