The goal of this book is to provide recent results on methods and tools to support collaboration in distributed software engineering processes. More and more companies are moving from traditional software factory models towards virtual organisation models, where independent institutions, departments, and groups of specialised individuals converge in a temporary network with the aim of utilising a competitive advantage or solving a specific problem.

Workflow and computer supported cooperative work technologies are primary enablers for virtual organisations and project teams, as people and institutions in a network make substantially more use of computer mediated channels than physical presence to interact and cooperate. This book collects research contributions from several authors of different countries and includes latest results from three research projects funded by the European Union within the Information Society Technologies (IST) 5th Framework Programme.
