Specifically,thework outlines how FOSS teams experience disagreements not only arising out of the directactionofworkingonasoftwareproject,butalsoconcerningthenormsof the group, such as ideology, mission and values. Conflict as a team process is thusmorethanataskbyproduct;inlong-termorientedself-organizingteams,it is a self-reflexive process that can stimulate community evolution, and in some cases,dissolution. Normative conflict is not only a novel addition to conflict theory, but also a factor with significant impact on the health of open collaborative communi- ties. Empirical findings suggest normative conflict to be the strongest overall predictor of developer retention, having both a direct negative effect, as well as throughexacerbatingothertypesofwork-drivenconflict. The dissertation traces the discovery (through interviews and community engagement),operationalization(throughdevelopmentandrefinementofanor- mativeconflictscale)andgeneralization(followingawidesurvey)ofnormative conflictaspartofanupdatedconflictframeworkforongoingdistributedvirtual workgroups. The dissertation thus presents a theoretical, methodological and practical contributiontounderstandingconflictinvirtualcommunitiesandorganizations. Theoretically, the work elucidates and provides support for the expansion of our existing understanding of conflict in distributed teams. Methodologically, the work provides a validated set of measurement tools for the updated conflict framework. Finally, the dissertation examines various team structural factors that may stimulate or reduce conflict occurrence, offering practical advice for communitybuildingandmaintenance. viii
