Interviews and workshops with stakeholders and practitioners were particularly useful in the absence of relevant literature for qualitative variables to validate the causal relationships among variables. During the interviews, two or three researchers collected notes in parallel. The notes were then compared to obtain a consistent interpretation of elicited mental models. In the workshop, we adopted more structured knowledge elicitation techniques, such as questionnaires, brainstorming, shared diagrams and maps to compile, individually or in a team, to obtain new structural insights. 
However, it should be mentioned that to ensure the protection of the personal data of the key informants involved in the interviews and the workshop, the related data cannot be accessible (according to the paragraph 2.2 of the Data Management Plan of the Horizon 2020 project PERCEIVE).
