The term 'digital thread' was first used in the Global Horizons 2013 report by the USAF Global Science and Technology Vision Task Force.<ref name=":0">{{Cite web |url=https://www.hsdl.org/?view&did=741377 |archive-url=https://web.archive.org/web/20210930134509/https://www.hsdl.org/?view&did=741377 |archive-date=2021-09-30 |title=Global Horizons Final Report |last=USAF Global Science and Technology Vision |first=Task Force |website=[[Homeland Security Digital Library]] |url-status=unfit |access-date=2022-06-06}}{{cbignore}}</ref> 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."<ref>{{cite journal |last1=Singh |first1=Victor |last2=Willcox |first2=K.

Although digital thread and [[Digital twin]] are "every so often understood to be synonymous...they are not the same as Digital Twin relies on real-time data from its physical counterpart".<ref name=":3" /> "In short, digital thread describes the process while digital twin symbolizes technology".<ref name=":4">{{Cite journal |last=Daase |first=Christian |last2=Haertel |first2=Christian |last3=Nahhas |first3=Abdulrahman |last4=Volk |first4=Matthias |last5=Steigerwald |first5=Heiko |last6=Ramesohl |first6=Achim |last7=Schneider |first7=Bernd |last8=Zeier |first8=Alexander |last9=Turowski |first9=Klaus |date=2023 |title=Following the Digital Thread – A Cloud-Based Observation |url=https://linkinghub.elsevier.com/retrieve/pii/S1877050922024723 |journal=Procedia Computer Science |language=en |volume=217 |pages=1867–1876 |doi=10.1016/j.procs.2022.12.387}}</ref> "Compared to the digital twin, the digital thread can support decision-making by designing and regulating the data interaction and processing instead of high-fidelity system models".<ref name=":1" />

A digital thread enables a [[Digital twin]] by ensuring that incoming data is made uniform and easily accessible through the three main data chains:<ref name=":5" />:

# '''The Product Innovation chain''' - Product designs, processes, and design flow are incorporated into the digital thread<ref name=":5" />

# '''The Enterprise Value chain''' - Supplier information, material data, and manufacturing processes are incorporated into the digital thread.<ref name=":5" />.

# '''The Field and Service chain''' - Maintenance manuals and part availability are incorporated into the digital thread.<ref name=":5" />.

Enabling a [[Digital twin]] could result in petabytes of data,<ref name=":6">{{Cite book |last=Darrington |first=John Wayne |title=The DeepLynx Data Warehouse |publisher=Idaho National Laboratory |year=2022 |language=en}}</ref>, and "necessitate the use of highly sophisticated tools and software."<ref name=":6" />
