The way this study has used the "best-fit" approach has facilitated the investigation of how three hypothesized constructs of political, economic, and social barriers can deepen our knowledge of their impacts on small and medium-sized enterprises (SMEs)' internationalization within a small developing country context. Based on a quantitative analysis of the three hypothesized barriers, we used the "best-fit" approach to measure the extent to which the SMEs' internal variables like people, products, services, and practices might best fit some of the people and non-people factors external to the businesses. The application of the "best-fit" approach onto the three hypotheses-politics (H1), social (H2), economics (H3), helped us in explaining the major social and politico-economic barriers faced by a developing economy' (Bangladeshi) SMEs' internationalization despite previous literatures' emphasis on the impacts of globalization, market drivers or their oversight. Based on the findings, we point to future research trajectory. This study used primary survey data from 212 Bangladeshi SMEs and successfully validated an HR model by using Smart PLS3 software. The results from the hypotheses were used to produce the HR model to help SMEs identify the significance of people and economic factors and propose these aspects for inclusion in the "best-fit" approach, SME, and globalization research.
