Arne has organized David Anderson's first training in Germany in early 2009 and has ever since closely collaborated with David. Amongst many other things he has translated David's defining book 'Kanban' into German with Henning Wolf, blogged and talked about Kanban on many conferences and has triggered lots of activity in the German community, such as founding the Limited Wip Societies Hamburg chapter. In 2011 he has organized the Lean Kanban Central Europe Conference in Munich to great success. This book is only one of the latest of his many activities.
Markus attended David Anderson's first training in Germany in early 2009 and went on implementing Kanban a week later with a small team. Since then he has brought Kanban to at least 15 teams across his organization in Europe and constantly reports about the results in the field in writing and talks. He also contributed a chapter on applying Kanban to Portfolio Management in the German translation of David's 'Kanban'. Amongst other community activities, he founded Berlins chapter of the Limited Wip Society.
