“…Playing the key role of reflecting an extensive body of information and experience into a study, knowledge elicitation is a core aspect of constructing a reliable causal map.

In this respect, this study combines documents and workshops since the initial map that was built based on literature was then evaluated, revised, and enriched through an expert workshop.…”
