Questionnaire Development and Data Collection

We did not focus on a specific industry sector because we attempted to obtain a more general idea of supply chain risks in Germany. In particular, we wanted to include manufacturing and process industries. 

Additionally, we collected data pertaining to the types of supply chains the respondents were involved in (domestic vs. global and simple vs. complex). In particular, the respondents had to indicate (1) if their firms rely on global supplier networks, and (2) if they consider their supply chains to have a high degree of complexity. The means for these two items were on or close to the scale mean of three (3.00 and 3.18) and the standard deviations were around one (1.37 and 1.01). This shows that on average the respondents reported on a fairly homogeneous set of supply chains.
