Who is this presentation for?

  • Development managers, product owners, technical leads, and change agents

Prerequisite knowledge

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

What you'll learn

  • Understand why organizations create silos and discover how to turn those forces to your benefit
  • Learn strategies for encouraging change
  • Explore a plan to start implementing InnerSource at 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.
