Abstract : Zero-defect manufacturing (ZDM) represents a transformative approach aimed at eliminating defects during the production process rather than correcting them post-production. This paper explores the integration of digital feedback loops—a continuous data-driven mechanism that captures real-time performance, quality deviations, and equipment behavior to proactively correct anomalies before defects occur. By leveraging industrial Internet of Things (IIoT), artificial intelligence (AI), and advanced process analytics, manufacturers can close the loop between production data and corrective action. The study outlines the architecture of digital feedback systems, their deployment in different industrial sectors, and the benefits in quality assurance, cost reduction, and predictive control. Through a critical analysis of case studies and recent technological advancements, the paper provides a comprehensive roadmap for adopting ZDM in smart manufacturing environments.
Keywords: Zero-defect manufacturing, digital feedback loops, quality assurance, Industry 4.0, predictive analytics, smart manufacturing, IIoT, real time monitoring.
