Transitioning to InnerSource: Increase delivery velocity, enable smooth collaboration, and produce quality software

Danese Cooper (NearForm), Cedric Williams (PayPal), Silona Bonewald (Hyperledger)
9:30–13:00 Wednesday, 19/10/2016
Collaboration and community
Location: Buckingham Room Level: Intermediate

Prerequisite knowledge

  • A general familiarity with software engineering methods
  • An awareness of open source
  • Experience with older engineering culture challenges
  • A willingness to consider change

What you'll learn

  • Understand how to begin to implement InnerSource in your organization


InnerSource applies the best lessons from open source to proprietary engineering and transforms the cultures that use it. Benefits include increased delivery velocity, smoother collaboration between groups, higher-quality development, and documentation that appears without having to resort to threats of removing the soda machine.

Danese Cooper, Cedric Williams, and Silona Bonewald examine the factors that keep software teams from collaborating effectively, explore the model of development used for Apache Software Foundation projects, and talk about ways to bridge the two approaches. Danese, Cedric, and Silona dig into examples from PayPal’s and other companies’ journeys to incorporate more open source development practices and discuss what worked and what didn’t. You’ll learn practical guidelines and business justifications for building InnerSource practices in your organization, as well as some anti-patterns to watch out for.

Materials will be made available in a booklet format.

Silona Bonewald


Silona Bonewald is vice president of community architecture at Hyperledger, where she’s responsible for facilitating the creation of the community metapatterns and processes that a global organization like Hyperledger requires. Silona has been involved in open source communities for over 14 years and has helped four companies transition from proprietary to open source. Most recently, she led the InnerSource efforts at PayPal, helping bottleneck teams remove years of backlog and promote collaboration across BUs. She continues to work on the creation of the InnerSource community with a strong focus on business integrations. She hopes to bring that knowledge into her work at Hyperledger.
