What It Means and Why It Matters
Achieving precision, tight tolerances, and compliance in aerospace engineering and manufacturing requires consistency and repeatability – critical standards that are only met by adhering to strict process controls.
Aerospace and defense manufacturing is only growing more advanced and complex. Making smart, data-driven decisions that are traceable throughout the product lifecycle only reinforces a manufacturer’s commitment to precision and reliability and closes any gaps from disconnected processes.
A Digital Thread Enables the Capture and Use of Knowledge
The Aerospace Industries Association defines digital thread as “a linked set of digital artifacts whose consistency is actively managed throughout the lifecycle of a product, process, or system.”
In many cases, the digital thread has been considered central to digital transformation within the aerospace industry; it unifies the data flow from disparate technologies and disciplines like AI, big data, modeling and simulation, and IoT to impact decision making with consideration to the challenges, complexities, and quickly-evolving nature of the industry.
Every stakeholder on a project can turn to a single source of truth to access:
- Design models
- Material specifications
- Machining instructions
- Quality testing data
- Inspection records
Where siloed systems and disconnected data handoffs can lead to catastrophic manufacturing errors, the digital thread establishes connectivity between the original design intent and production, and complete visibility across the product lifecycle.
Complete Traceability Completely Changes the Game
Building aerospace parts and assemblies is a massively complex undertaking involving thousands of components with individual data from their design, manufacture, testing, and maintenance.
A digital thread enables design, manufacturing, supply chain, and maintenance teams to access and contribute to that data, which means design improvements can be made early, issues can be caught before manufacture, the supply chain is using the most current information, and maintenance has a product history to follow. Other immediate benefits include:
- Data-based predictions for how design changes will impact performance, safety, and cost
- Reduced paperwork, rework, and costly delays or errors through more informed decision making
- Optimized resources based on more consistent and repeatable product lifecycle data
- Increased manufacturing efficiency through improved responses and adjustments when the design changes or market demands shift
Connecting the Physical and the Virtual: Implementing a Digital Thread
Takahiro Fujimoto, manufacturing management expert and professor, defined the digital thread as having three distinct degrees of integration:
Integradeability: How data and models are connected using information technology. Are they findable and accessible?
Interoperability: Enabling the collaborative execution of models.
Composability: The combining of simulation assembly and execution from component models to ensure reusability.
A 2025 OpsHub study found that while more than 90% of manufacturers have digital thread initiatives planned or in progress, successful implementation falls under 3% in the aerospace and defense industries specifically.
Successful adoption requires cross-organizational behavior and process changes, specifically to business operations, critical systems, and culture.
- Business Operations
Making a business case for adopting a digital thread to achieve ROI for the costs associated with adopting a digital thread can quickly undermine its importance to business operations. Instead, identify the appropriate metrics to support digital thread adoption, such as:
- Partner organizations using a digital thread that would benefit from your company’s adoption to establish continuity, security, and intellectual property protection.
- Cost modeling that demonstrates how a digital thread enables better discovery and traceability.
- Opportunities to make compliance more efficient by having a complete and readily accessible database of product information.
- Critical Systems
The digital thread aligns with the aerospace and defense industry’s demands for precision machining and complex part production. When design intent is connected directly to production, it supports the integration of critical systems, such as PLM, MES, ERP, and QMS, to create a cohesive digital ecosystem that drives operational excellence.
Critical systems considerations should include:
- A set of standards guiding how different parts of the digital thread will be connected.
- An infrastructure capable of supporting the digital thread, and that leverages automation to increase the capability and efficiency of data capture.
- How accurate, precise, and detailed the digital data and virtual models are relative to the physical manufacturing components.
- Culture
Outside of technical considerations, the culture shift necessary to implement a digital thread is an often major hurdle to overcome. Getting it up and running and then ensuring proper and long-term use can be challenging. And because a digital thread touches every area of a company, it simply isn’t possible without a cultural shift.
Comprehensive employee education and training will make the transition more seamless and universally understandable, and if your company already has a training component built into career development, consider utilizing it for educating about the digital thread.
Turning Disparate Data into a Competitive Advantage
A digital thread enables manufacturers to go beyond basic technology initiatives to implementing a strategic capability that directly impacts quality, speed, and traceability – all while managing cost and complexity.
Aerospace and defense manufacturing is only growing more advanced and complex, and making smart, data-driven decisions that are traceable throughout the product lifecycle. It only reinforces a manufacturer’s commitment to precision and reliability and closes any gaps from disconnected processes.
Deliver better products faster and more efficiently – and with complete traceability from start to finish.
