Abstract: The digital thread is rapidly emerging as a transformative enabler in modern manufacturing and engineering, especially within the framework of Product Lifecycle Management (PLM). By establishing a seamless, traceable, and interconnected flow of data across a product's lifecycle—from concept to retirement—the digital thread supports real-time decision-making, enhances product quality, reduces time-to-market, and fosters innovation. This paper explores the conceptual foundations of the digital thread, its integration with PLM systems, enabling technologies such as IoT, digital twin, and cloud computing, and its impact on design, manufacturing, and service stages. It also discusses implementation challenges, data interoperability issues, and security concerns, concluding with future research directions and recommendations for industry adoption.
Keywords: Digital Thread, Product Lifecycle Management (PLM), Digital Twin, Smart Manufacturing, Data Interoperability, Industry 4.0
