This book is intended to bring, from a managerial perspective, the several aspects needed when introducing InnerSource methodologies into enterprises.

This book is a work in progress process where anyone is more than welcome to contribute in any possible way. Ideas, comments, typos, full paragraphs or sections would be great. This repository aims at bringing specialized knowledge from the industry within this respect in a way that this is useful for third parties. For this, we are actively looking for reviewers that can help in this process. For those that have already contributed to the book, thanks a lot!

You can find more information about the process in the contributing section.

Who is fostering this initiative?

We thank Bitergia (especially José Manrique López and Daniel Izquierdo) for starting this book and seeding it with its main areas of expertise such as the usual metrics and KPI's to use, the methodology, the metrics strategy around your general InnerSource strategy and the infrastructure needed to have a successful InnerSource journey within a company.

The book is now managed by the ISPO Working Group. It is open for use and contribution by anyone interested in InnerSource. Come join us and contribute!

Add in your own scenarios to the graph! See the "Metrics" section of


For further reading, we encourage you to participate in the InnerSource Commons, a non-profit foundation where dozens of companies are already sharing experiences and working to improve their craft of InnerSource.
