The flow chart starts with a text box positioned at the top left, labeled “Study Domain (Tourism Service Innovation).” A downward arrow from this text box, points to another text box positioned vertically below it. The text in the second text box reads, “Sustainable tourism Innovation, Competitive and sustainability performance.” A rightward arrow from this second text box leads to a larger third text box with rounded corners. The third text box contains 6 smaller text boxes arranged in a 2 by 3 pattern. From top to bottom, the text boxes on the left are labeled as follows: “Research gate,” “PubMed,” and “Google Scholar.” From top to bottom, the text boxes on the right are labeled as follows: “Semantic Scholar,” “TreeHugger,” and “Emerald.” A downward arrow from the third text box, points to the fourth text box positioned vertically below it, labeled “Filtering Articles based on Title, Abstract and Keywords.” A downward arrow from this fifth box points to a diamond decision box positioned vertically below it and labeled “Is this article relevant to study subject?” A downward arrow from this diamond decision box leads to a pair of boxes; the smaller box is positioned on top of the larger one. The smaller box is labeled “Yes” and the larger box is labeled “Collecting articles as selected sample.” A downward arrow from this text box leads to a second diamond decision box labeled “Have all articles studied?” A rightward arrow from this diamond decision box points to a text box positioned at the same level, labeled “Yes.” A downward arrow from this box points to a text box positioned vertically below it, labeled “Terminating screening articles.” A downward arrow from this box points to a text box positioned vertically below it, labeled “Including for scanning review of literature.” A rightward arrow from the “Is this article relevant to study subject?” diamond leads to a text box labeled “No.” A downward arrow from this text box points to a text box positioned vertically below it, labeled “Deleting articles.” A leftward arrow from the “Have all articles studied?” diamond, labeled “No” points back to the “Is this article relevant to study subject?” diamond.Literature review flowchart.
