Purpose — This study explores the strategic role of digital knowledge management (DKM) in transforming project management information system (PMIS) practices across industries. While DKM adoption is accelerating, its systemic innovation, long-term outcomes, and cross-sector applicability remain insufficiently explored. Design/approach — The research integrates quantitative, qualitative, and mixed-methods studies. Sources were systematically selected from Q1-Q2 journals (2015–2024) indexed in the Web of Science. Findings — The study adheres to PRISMA guidelines and applies thematic and narrative synthesis to capture key insights. The findings identify three main contributions of DKM to project management: improving operational efficiency through structured knowledge sharing and coordination, enabling innovation via real-time data-driven insights, and promoting sustainability by aligning project outcomes with economic, environmental, and social objectives. However, significant gaps remain regarding the longitudinal effects of DKM beyond initial implementation phases, mechanisms of organizational learning from digital practices, and DKM applications in under explored sectors such as healthcare and education. Practical implications — the findings provide actionable insights for practitioners, project leaders, and policymakers seeking to integrate DKM into digital transformation strategies. For researchers, this study offers a conceptual foundation and highlights future research opportunities in underrepresented domains and long-term knowledge governance. Theoretical implications — it integrates DKM into project management literature, highlighting its role in enhancing innovation, efficiency, and sustainability. The mixed-methods approach also contributes methodologically by unifying diverse research designs into a coherent synthesis. Originality/value — this study offers a comprehensive studies on DKM in project management, providing new insights into its impact on efficiency, innovation, and sustainability across various sectors.
