Data collection and analysis

In this chapter, I present methodological aspects related to data collection and analysis. I present data sources within each case including detailed information with regard to interviewee characteristics. The data collection approach differs between the pilot Case A and the four follow up Cases B‐E. In consequence, I present the longitudinal data collection approach of the pilot case first and continue with the data collection at Cases B‐E. I end with a description of data analysis procedures.
