Global software teams face challenges when collaborating over long distances, such as communicating changes in the project. During a four-month case study at IBM Ottawa Software Lab we observed the collaboration patterns of a multi-site development project team. In this period, we inspected project documentation, interviewed team leaders, attended project(More)
Because of intense collaborative needs, requirements engineering is a challenge in global software development. How do distributed teams manage the development of requirements in environments that require significant cross-site collaboration and coordination? In this paper, we report research that used social network analysis to explore collaboration and(More)
Socio-technical congruence is an approach that measures coordination by examining the alignment between the technical dependencies and the social coordination in the project. We conduct a case study of coordination in the IBM Rational Team Concert project, which consists of 151 developers over seven geographically distributed sites, and expect that high(More)
Research is emerging on how end users can correct mistakes their intelligent agents make, but before users can correctly “debug” an intelligent agent, they need some degree of understanding of how it works. In this paper we consider ways intelligent agents should explain themselves to end users, especially focusing on how the soundness and(More)
Sharing knowledge in a timely fashion is important in distributed software development. However, because experts are difficult to locate, developers tend to broadcast information to find the right people, which leads to overload and to communication breakdowns. We study the context in which experts are included in an email discussion so that team members(More)
Theories of human behavior are an important but largely untapped resource for software engineering research. They facilitate understanding of human developers’ needs and activities, and thus can serve as a valuable resource to researchers designing software engineering tools. Furthermore, theories abstract beyond specific methods and tools to(More)
Assessments have been shown to have positive effects on learning in compulsory educational settings. However, much less is known about their effects in discretionary learning settings, especially in computing education and educational games. We hypothesized that adding assessments to an educational computing game would provide extra opportunities for(More)
What does a user need to know to productively work with an intelligent agent? Intelligent agents and recommender systems are gaining widespread use, potentially creating a need for end users to understand how these systems operate in order to fix their agent's personalized behavior. This paper explores the effects of mental model soundness on such(More)
