Software development means collaboration, and increasingly this collaboration must cross boundaries of organizational and national culture. Projects in multi-cultural settings involve countless challenges, including not only collaboration, but also everything from existing project planning and management, and even simple communication. Moreover, software development methods might need to be transformed to work at all. The aim of this tutorial is introduce models of culture, and to explore the impact of cultural differences on software development processes and methods, especially novel approaches such as agile development. The tutorial will be organized around two collaborative games to illustrate culture in the software development workplace. The first game, 'Wheel of Culture', involves building and comparing balance wheels that show how organizations vary in their cultural values. The second game, 'Cultural Monopoly' is a novel board game designed by us for small groups to explore the effects of cultural difference on a development project.
