The process flows primarily from left to right with connecting arrows between rectangular boxes. At the top left, a box labeled “Keywords Identification for the Study” connects to a box on the right labeled “Synonym Expansion for the Study”. From the synonym expansion box, a downward arrow leads to a box labeled “Literature Search Using 3 Databases (Scopus, ScienceDirect, E B S C O)”. An arrow from “Keywords Identification for the Study” also leads to the literature search box. From the literature search box, a downward arrow leads to “Article Selection Using PRISMA method”. This box connects downward to “Review Articles for Factors Identification and Recording”. From this review box, two parallel paths extend to the right. The upper path leads to a box labeled “Develop Factors Interrelationship Matrix”. The lower path leads to a box labeled “Develop Author-Factor Matrix”. From the “Develop Factors Interrelationship Matrix” box, two boxes branch to the right in a vertical sequence: “Develop Causal Loop Diagram using Vensim Software” and “Develop Degree of Centrality Table”. From the “Develop Author-Factor Matrix” box, two boxes branch to the right in a vertical sequence: “Develop Pareto Chart for Influential Factor” and “Develop S L R frequency Table”. All four boxes on the right side, causal loop diagram, degree of centrality table, Pareto chart, and S L R frequency table, connect via arrows to a final box on the far right labeled “Analysis and Synthesis”.Flowchart for SLR data collection and analysis method.
