Coordination of interdependent tasks across geographical, temporal and socio-cultural boundaries has been identified as a critical antecedent to global software development (GSD) team performance. Since GSD teams are increasingly required to achieve software development agility and respond to changing business requirements, conventional plan-driven software development methods become inadequate to manage the cross-boundary dependencies. To cope with this issue, there is an emerging trend of implementing change-driven agile methods in GSD; we call this practice agile GSD. This paper focuses on the formulation of coordination strategies in agile GSD. We argue that Coordination Theory (CT) can serve as a useful lens to develop a deeper understanding of the formulation process. We present a case study in a leading software development company using agile GSD and present preliminary results by applying the lens of CT.
