Task Bubbles, Artifacts, Shared Emotion, and Mutual Focus of Attention: A Comparative Study of the Microprocesses of Group Engagement
通过比较两个软件开发项目的田野研究，运用民族志方法考察相互依赖的个体如何发展并维持对共享任务的共同注意力焦点，即群体参与过程。
Based on a comparative field study of two software development projects, we use ethnographic methods of observation and interview to examine the question of how interdependent individuals develop and maintain mutual focus of attention on a shared task, which we define as the group engagement process. Drawing on Randall Collins' interaction ritual theory, we identify how mutual focus of attention develops through the presence of a task bubble that focuses attention by creating barriers to outsiders and through the effective use of task-related artifacts. Shared emotion both results from mutual focus of attention and reinforces it. Through our comparison between the two projects, we show that the group engagement process is enabled by factors at the individual (individual engagement), interaction (frequency and informality of interactions), and project (compelling direction of the overall group) levels. Our focus on group interaction episodes as the engine of the group engagement process illuminates what individuals do when they are performing the focal work of the group (i.e., solving problems related to the task at hand) and how they develop and sustain the mutual focus of attention that is required for making collective progress on the task itself. We also show the relationship between the group engagement process and effective problem solving.
