Definition was missing any references to government task forces and academic papers that defined the term. Previous definition appears to be self-serving to a technology company selling digital twin software - a different concept. |

The term '''Digital Thread''' was first used in the Global Horizons 2006 report by the USAF Global Science and Technology Vision Task Force.<ref>{{Cite web|url=https://www.hsdl.org/?abstract&did=741377|title=Global Horizons Final Report|last=USAF Global Science and Technology Vision|first=Task Force|website=Homeland Security Digital Library|access-date=2021-09-30}}</ref>
In the report, the term Digital Thread is defined as “the use of digital tools and representations for design, evaluation, and life cycle management.” The term Digital Thread was further refined in 2018 by Singh and Willcox at MIT in their paper entitled Engineering with a Digital Thread.<ref>{{Cite web|url=https://arc.aiaa.org/doi/10.2514/1.J057255|title=Engineering with a Digital Thread|last=Singh|first=Victor|website=Aerospace Resource Central|access-date=2021-09-30}}</ref> In this academic paper the term Digital Thread is defined as "a data-driven architecture that links together information generated from across the product lifecycle and is envisioned to be the primary or authoritative data and communication platform for a company’s products at any instance of time."
More narrowly, the digital thread is also used to refer to the lowest level design and specification for a digital representation of a physical item. The digital thread is a critical capability in model-based systems engineering (MBSE) and the foundation for a digital twin.
The term digital thread is also used to describe the traceability of the [[digital twin]] back to the requirements, parts and control systems that make up the physical asset. <ref>{{Cite web|url=https://www.gardnerweb.com/articles/what-are-digital-twins-and-digital-threads|title=What Are Digital Twins and Digital Threads?|last=Gould|first=Lawrence S.|website=Automotive Design & Production|access-date=2021-07-27}}</ref> == References ==
