4. RESULTS

Here we present the results of our investigation. First, we outline the overall framework and definition to answer RQ1, then we answer RQ2 and RQ3 by reporting first the initial results from the interview in step 1, followed by the additional validation results from step 2 (the longitudinal case) and step 3 (the cross-company interview). We also add, for RQ 2.3, RQ2.5 and RQ3, the results from the questionnaire organized during the data collection of step 3. Finally, we report the results from RQ4 related to the longitudinal case study.
