Revisiting benefits of Quality 4.0: insights from systematic literature review

Abstract

The rapid expansion of research on Quality 4.0 (Q4.0) reflects its increasing strategic relevance in the era of digital transformation. While prior studies have explored various implementation aspects, there remains a need for a more integrated understanding of the tangible benefits organizations gain through successful adoption. Existing contributions remain dispersed across disciplines, making it difficult to quantify the multifaceted outcomes of this transition. Therefore, this study aims to systematize the primary benefits and value-added outcomes resulting from Q4.0 implementation. A systematic literature review was conducted, analyzing empirical research papers published between 2017 and 2025 retrieved from the Web of Science (WoS) and Scopus databases. The review synthesizes the performance improvements, operational efficiencies, and strategic advantages that stem from Q4.0 initiatives. The findings provide a structured foundation for future research examining the strategic impact of digital quality management. Based on the results, executives, shareholders, and quality professionals can better evaluate the value proposition of Q4.0 and align digital initiatives with long-term organizational objectives.
