<p>Agile software development offers a deceptively simple means to organise complex multi-participant software development while achieving fast delivery of quality software, meeting customer requirements, and coping effectively with project change. There is little understanding, however, of how agile software development projects achieve effective coordination, a critical factor in successful software projects. Agile software development provides a unique set of practices for organising the work of software projects, and these practices seem to achieve effective project coordination. Therefore, this thesis takes a coordination perspective to explore how agile software projects work, and why they are effective. The outcome of this research is a theory of coordination in co-located agile software development projects. To build a coordination theory, evidence was drawn from a multi-case study following the positivist tradition in information systems. Three cases of agile software development contributed to the theory, along with one additional non-agile project that contributed contrasting evidence. The findings show that agile software development practices form a coordination strategy addressing three broad categories of dependency: knowledge dependencies, task dependencies, and resource dependencies. Most coordination is for managing requirement, expertise, historical, and task allocation dependencies; all forms of knowledge dependency. Also present are task dependencies, which include activity or business process dependencies, and resource dependencies, which include technical or entity dependencies. The theory of coordination explains that an agile coordination strategy consists of coordination mechanisms for synchronising the project team, for structuring their relations, and for boundary spanning. A coordination strategy contributes to coordination effectiveness, which has explicit and implicit components. The primary contribution of this theory is an explanation of how agile software development practices act together to achieve effective project coordination. The coordination strategy concept can be used to select practices from agile methods to ensure software projects achieve effective coordination. In addition, once operationalised in future work, the well-grounded theoretical concepts developed in this research will provide valuable tools for measuring the coordination effectiveness of agile method adoption and adaptation.</p>
