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.
