    7. Apache Software Foundation • US Non-Profit • Provides legal and infrastructure support • Completely volunteer organization • 1000+ committers, 200+ members • 60+ open source projects
    8. Incubating Open Source Communities Which Why What How
    9. Which Community User Developer Involvement Public Contributor
    10. At The Core The community begins with the developers and contributors. The larger and more open the developer community, the greater chance for sustained activity and growth.
    11. Contributors Users Developers
    12. A Note on Size • Most developer communities are small • Even with large developers, most of the development is usually by a small number of developers • Apache requires minimum of 3 independent votes for a release

    40. People • Meritocracy • Clearly define: • Roles • Expectations • Qualifications People Customs Ownership Shared Goals Communication
    41. People Roles The meritocracy enables various roles: user | developer | committer | PMC member | ASF member User user is someone that uses our software. They contribute to the Apache projects by providing feedback to developers in the form of bug reports and feature suggestions. Users participate in the Apache community by helping other users on mailing lists and user support forums. The passive users are also known as lurkers. Developer developer is a user who contributes to a project in the form of code or documentation. They take extra steps to participate in a project, are active on the developer mailing list, participate in discussions, provide patches, documentation, suggestions, and criticism. Developers are also known as contributors. Committer committer is a developer that was given write access to the code repository and has a signed Contributor License Agreement (CLA) on file. They have an apache.org mail address.... People Customs Ownership Shared Goals Communication

    55. Code • Directly useful to developers (itch) • Builds • Common standards • Composable • Consistent • Improvable
    56. Composability ... codebases that are more modular or have more option value increase developers’ incentives to join and to remain involved in an open source development effort; and decrease the amount of free-riding in equilibrium. The Architecture of Participation: Does Code Architecture Mitigate Free Riding in the Open Source Development Model Baldwin and Clark, 2005 http://www.people.hbs.edu/cbaldwin/DR2/BaldwinArchPartAll.pdf
