  Editor Introduction: Today software engineering is characterized by two
strong trends: agile and distributed. Both together are increasingly demanded
and challenge teams and projects due to lack of discipline, insufficient
transparency, agile "ping pong" and thus overheads and rework. Authors Fabio
Calefato and I describe current technologies and tools for agile collaboration.
I look forward to hearing from both readers and prospective column authors
about this column and the technologies you want to know more about. -- Christof
Ebert
