Systematic Literature Search
Ethridge said, ‘The central purpose of the literature review is to provide the researcher and the reader with an understanding of the body of literature as it relates to the current or proposed research. The purpose includes an understanding of the strengths and weaknesses of the prior research’ (Ethridge, 2004). I have followed the standard procedures of data collection; such as, identification, screening, eligibility, and inclusion of studies (Khan, Kunz, Kleijnen, & Antes, 2003; Xiao & Watson, 2017). This paper attempts to collect, appraise, and synthesize available empirical evidence that meets pre-defined criteria in order to achieve the research purpose. There are different types of literature review techniques; such as, systematic literature review, critical review, content analysis, meta-analysis, bibliometric analysis, citation analysis, word and co-word analysis, co-authors and affiliations analysis etc. The application of systematic literature review is observed in multiple disciplines (Fleary, Joseph, & Pappagianopoulos, 2018; Piccarozzi, Aquilani, & Gatti, 2018; Pisani, Reyes, & García, 2009; Ritz, Brewer, & Neumann, 2016).
