Collaborative Enterprise Architecture Enriching EA with Lean, Agile, and Enterprise 2.0 Practices

Writing a book is a strenuous journey. We are indebted to many people who helped us along the way. Murali Padmanabhan, at the time coordinating the Tata Consultancy Services (TCS) learning and development initiative, established our early contact to Elsevier India. Without his efforts the book idea would never have taken off in the first place. We are sincerely grateful to the TCS management, in particular to Krishnan Ramanujam and Santosh Mohanty, for their motivation, support, and friendly eye toward the book. Hermann Klein and Ingo Rosenstein, by their kind permission, made it possible for us to work on the book project. Many thanks go to numerous colleagues at TCS, especially to Harish Iyer, Bernd Linowski, and Ameya Vanjari. They not only listened to our continuous rambles about architecture; they also provided many useful insights in return.
