Research on high-performance work systems (HPWS) has revealed a potential correlation between human resource management practices and organizational performance. However, most recent studies have primarily focused on developed countries, with limited representation from developing countries. Therefore, this study aims to investigate the impact of HPWS, based on the AMO model (abilitymotivation-opportunity), on financial, operational, and HR outcomes using scientific research journals in Iran's management field. The analysis includes 145 articles published between 2008 and 2019, which were examined through the meta-analysis method. The results demonstrate a positive effect of high-performance work systems on organizational performance. Additionally, HPWS practices exhibit a positive influence on financial and operational outcomes. However, the impact of HPWS practices on HR outcomes did not yield conclusive evidence. This study contributes to existing knowledge by categorizing organizational performance into three distinct outcomes and exploring the influence of these three HRM practices on such outcomes.
