Dear Dr. Winter, it was an exciting, refreshing and intensive seminar over all 4 days and I took away a lot of ideas that I would like to integrate into day-to-day business. It is always helpful to refresh and enlighten this knowledge, since operational blindness tends to cast long shadows over the current status. Best regards, Jörn Kamrad
