Table II summarizes the characteristics of the six cases. Differences and similarities in
theses dimensions were strived for. All contacted managers, who all hold positions
related to SCM, agreed to take part in the case studies. In average, they have been
working in their respective company for 14 years.
Data was collected from three sources. First, six semi-structured interviews were
held and recorded with at least one, in some cases two representatives. The interviews
were transcribed afterwards. In these interviews, interviewees were confronted with
the survey results. Second, annual reports were collected, if available. Third, additional
documents were provided by some participants, such as firm presentations and risk
management documents
