This paper presents a multifaceted qualitative Investigation of everyday conflict in six organizational work teams. Repeated interviews and on-site observations provide data on participants' perceptions, behaviors, and their own analyses of their conflicts, resulting in a generalized conflict model. Model evaluation indicates that relationship conflict is detrimental to performance and satisfaction; process conflict is also detrimental to performance; and task conflict's effects on performance depend on specified dimensions. In particular, emotionality reduces effectiveness, resolution potential and acceptability norms increase effectiveness, and importance accentuates conflict's other effects. Groups with norms that accept task but not relationship conflict are most effective. The model and the findings help to broaden understanding of dynamics of organizational conflict and suggest ways it can either be alleviated or wisely encouraged.
