  1. Ph.D. research: Method diffusion in large open-source projects Martin F. Krafft – 23 Nov 2007 Research report

  2. One slide on the Debian project • oldest GNU/Linux distribution: 14 years • among the largest OSS projects: • 1,100 developers + 2,500 contributors • 22,000 packages, 11 architectures • conservative & quality-oriented: prefer solid solutions to quick 'n' dirty ones • robust, secure, stable, Free • 100% volunteers, flat, meritocratic

  3. Definitions Method diffusion inlarge open-source projects • method: technique, tool, procedure • diffusion: introducing with the goal to cause adoption • large project: possessing a high inertia and complex self-dynamics

  4. Research basis • Debian's methods evolved over time • high interdependence of methods • stagnating efficiency in day-to-day activity • improved methods exist, but volunteers cannot be told to use them • under what conditions do volunteers adopt new methods (and thus change their workflow)?

  5. Approach • Grounded theory: collection of factors affecting adoption (semi-structured interviews, forums, literature)‏ • Community survey to sort/augment factors • Design of an initial framework • Delphi study to improve framework • Application and verification

  6. Contribution • A framework to assess diffusions in Debian • (no suitable framework seems to exists)‏ • maybe suitable to other FLOSS projectsif not, then can be used to compare projects • Improved workflows in Debian • Possible new insights into volunteer management

  7. Current status • Gained good understanding of qualitative research and relevant aspects of sociology • Complete thesis outline • Literature review is about 50% done • Six talks at Debian/OSS conferences • Conducted seven informal interviews • Master to Ph.D. transfer later today
