This study is driven by the national policy agenda, including the National Automotive Policy (NAP) and the New Industrial Master Plan (NIMP) 2030, the research aims to assess how sustainability oriented project management practices influence long-term project success beyond conventional metrics of cost, time, and scope. Anchored in the Triple Bottom Line (TBL) framework, this study adopts a quantitative research design to evaluate the extent of PSM implementation and the relationship between PSM and PSS. Data were collected through structured questionnaires adapted from established instruments and distributed to professionals across 250 automotive related companies in Malaysia. A total of 186 valid responses were obtained and met the adequacy. Descriptive statistics, factor analysis, correlation, and multiple regression analyses were employed to analyse the data. The analysis tools used was IBM SPSS Statistic Version 27. The findings revealed a positive and statistically significant relationship between PSM and PSS. Among the sustainability dimensions, social and economic practices demonstrated stronger influence on project sustainability success. Although significant, environmental practices showed a comparatively weaker effect. This research enhances the understanding of how sustainability practices influence project outcomes.
