In September 2018, my PhD research has been going on for three years. During our last meeting in June 2018, the supervisory committee advised to map out the research so far . This ‘research mapping’ allowed to illustrate the coherence between the case studies, literature review (including the state-of-the-art) and position the work in relation to existing research and relevant domains. In this way, consistency between the different aspects of the research will be made clear. Again: on the one hand, it was interesting to reflect upon the research activities and explorations of the past few years. On the other hand, it helped me to get a clearer idea of the future directions I want to explore.
