Enhancing human resources through lean and lean sixsigma : literature review

he repository164created [28] organized the classification into distinct tabs, each representing different165aspects of the research:166Tab 1: Database complete: This section includes all articles collected from various167sources, Scopus, Web of Science, and Google Scholar, based on the research questions168outlined in Section 2.3. Additionally, to enhance the comprehensiveness of the identified169studies, the snowballing technique was applied to both the seed articles from Elicit170[27]; [21] and the two review papers identified [14]; [24]. The articles retrieved through171this method are labeled as ’Snowballing’ in the repository [28], which explains why172some of them are more than five years old.173Tab 2: First selection: From the complete database, studies that mentioned both174Lean or LSS and Human Resources in the abstract were selected. Each selected article 175was then reviewed and classified based on their methodological focus, practical scope,176and theoretical contributions to the integration of Lean and LSS within or beyond the177Human Resources function (see Tab 2 for more explanation).178Tab 3: Final selection: The articles that explicitly utilize Lean or LSS for human179resources improvement are presented here, classified into cases with application and180without application. In this context, ”explicitly” refers to studies where the main and181stated objective of applying Lean or LSS is to improve HR processes. This excludes182studies where improvements in HR are merely incidental, indirect, or secondary183outcomes of broader organizational initiatives.
