3. METHODOLOGY

As visualized in Figure 1, this study’s research design was divided into three main steps, including six different phases. The first three phases address an exploratory case study, which was conducted in Step 1 (phases 1-3) and primarily refer to this publication’s original study [24] (see section 2.4). The following two steps were conducted as an extension to that study and included a longitudinal case study (Step 2, phase 4) and also a final cross-company focus study (Step 3, phases 5-6). Figure 1 also describes what activities were performed in each of the phases, together with the research methods used in each phase.
