Abstract:

The empirical study described in this paper addresses the issue of communication among members of a software development organization. In particular, we have studied interactions between participants in a review process. The question of interest is whether or not organizational relationships between the review participants have an effect on the amount of communication effort expended. The study uses both quantitative and qualitative methods for data collection and analysis. These methods include participant observation, structured interviews, graphical data presentation, and non-parametric statistics. The results of this study indicate that several organizational factors do affect communication effort, but not always in a simple, straightforward way. Not surprisingly, people take less time to communicate when they are familiar with each other, and when they work in close physical proximity to each other. However, certain mixtures of organizationally "close " and "distant " participants to an interaction result in more effort needed to communicate. Also, interactions tend to be more effort-intensive when they occur in a meeting, and when more people are involved. These results provide a better understanding of how organizational structure helps or hinders communication in software development.
