You may have heard the term Digital Threada lot from others.
It sounds like another Industry 4.0 or Industry 5.0 buzzword.
But the underlying idea is surprisingly simple:
A Digital Thread means that product information can move through your business without being repeatedly re-entered, misunderstood or lost.
For a small or medium-sized manufacturer, that can have a very practical impact.
Because the problem isn’t usually that you don’t have enough data.
The problem is that your data doesn’t always travel with the product.
Imagine This Simple Scenario
An engineer changes a component in a product.
The drawing is updated in CAD.
But what happens next?
Does PLM know?
Does the BOM change?
Does ERP receive the new part information?
Does purchasing know?
Does manufacturing know which revision to build?
Does quality know what changed?
Can you identify which customer shipments contain the old version?
If the answer involves emails, Excel files, phone calls and someone manually updating three different systems, you don’t really have a digital thread.
So, What Exactly Is a Digital Thread?
Forget the technical definition for a moment.
Think of the Digital Thread as the journey of product information.
For example:
Design → Product Data → BOM → ERP → Manufacturing → Quality → Product History
The idea is that information created at one stage should remain connected as the product moves through its lifecycle.
A change made by engineering shouldn’t disappear inside the engineering department.
It should be able to flow to the people and systems that need to act on it.
A digital thread allows a design change to move towards purchasing and the shop floor without someone having to retype the information.
That’s the essence.
Why Does This Matter for SMB Manufacturers as well?
A large OEM may have dedicated teams managing product data, integration and digital transformation.
An SMB often doesn’t.
Instead, the same engineer may be responsible for:
- Designing the product
- Updating drawings
- Maintaining BOMs
- Answering manufacturing questions
- Supporting ERP data
- Fixing inconsistencies
- And sometimes maintaining the PLM system
This creates a dangerous situation.
The business may have sophisticated software, but the actual information flow still depends on individuals remembering what needs to be updated where.
As the company grows, this becomes increasingly difficult to manage.
The Three Big Problems a Digital Thread Addresses
1. Re-entering the same information
Suppose engineering creates a new part.
Someone then manually creates that part in ERP.
Another person updates a spreadsheet.
Someone else updates the manufacturing BOM.
Every manual handoff introduces another opportunity for an error.
A connected digital thread reduces unnecessary re-entry.
2. Different systems telling different stories
Imagine:
CAD: Part A-102, Revision C
PLM: Part A-102, Revision B
ERP: Part A-102, Revision B
Production spreadsheet: Part A-102, Revision A
Which one should the factory build?
This isn’t a theoretical technology problem.
It can become a production, quality and customer problem.
A digital thread aims to establish a controlled flow of product information so that the right systems and users receive the right information.
3. Losing the history of decisions
A product isn’t static.
It changes continuously.
Materials change.
Suppliers change.
Designs change.
Manufacturing processes change.
Customer requirements change.
A useful digital thread allows the organization to understand not just what the product looks like today, but how it got there. That history becomes valuable when investigating quality issues, managing engineering changes, supporting customers or preparing for audits.
Where Does PLM Fit?
This is where PLM becomes particularly important.
PLM can act as the central product-information layer between engineering and the rest of the business.
A simplified architecture could look like:

PLM

ERP

MES / Manufacturing

Quality & Product History
Each system has a different purpose.
CAD is primarily concerned with design.
PLM manages product information, structures, revisions and changes.
ERP manages business processes such as purchasing, inventory and costing.
MES connects manufacturing processes and production data.
The Digital Thread is about connecting these pieces around the product.
It isn’t necessarily about replacing all your systems with one giant platform.
The BOM Is Where Things Get Interesting
One of the best ways to understand the Digital Thread is through the Bill of Materials.
Engineering may create an Engineering BOM.
Manufacturing may need a Manufacturing BOM.
ERP may hold another representation.
If these are disconnected, people start comparing lists manually.
But imagine instead that a controlled product structure flows from engineering into downstream processes.
A design change can trigger the appropriate downstream updates.
Purchasing sees what needs to change.
Manufacturing sees what should be built.
Quality knows which revision applies.
The business has greater confidence in its product data.
That is the Digital Thread becoming tangible.
Digital Thread Doesn’t Mean “Automate Everything”
This is an important distinction.
A common mistake is to think: Digital Thread = connect every system immediately.
That’s not necessarily the right approach for an SMB.
Your first step should be to understand where the data actually breaks.
Where does someone:
- Re-type information?
- Copy data into Excel?
- Send an email?
- Ask another person for the latest version?
- Manually reconcile two BOMs?
- Check which drawing is current?
These are the points where your digital thread is weak.
Map where the data breaks, then decide what to simplify, fix the underlying data and only then automate the flow.
The Digital Thread Doesn’t Start With AI
This is particularly relevant today.
There is enormous excitement around AI in manufacturing. But AI doesn’t magically create reliable product information.
If your part numbers are inconsistent…
If your BOMs are unreliable…
If your engineering history is scattered across emails…
If your systems disagree…
then putting AI on top doesn’t solve the underlying problem.
It may simply allow you to process bad information faster.
A much more sensible sequence is: Clean the data → Connect the systems → Automate the flow → Then apply AI.
Once the digital thread exists, AI becomes much more interesting.
You can start asking questions such as:
- What products are affected by this engineering change?
- Which customers received the previous revision?
- Which components are likely to be impacted?
- What changed between these two product versions?
- Where has this part been used?
That’s when product data begins moving from a system of record toward a system of intelligence.
A Checklist to find out If Your Digital Thread Is Broken
Ask yourself these five questions:
If several answers involve spreadsheets, emails or manual intervention, you’ve probably found opportunities to strengthen your digital thread.
Start With One Thread, Not the Whole Factory
An SMB doesn’t need to digitally connect everything on Day One.
Pick one important product or workflow.
For example:
CAD → PLM → ERP
Or
Engineering Change → BOM → Manufacturing
Map the current process.
Identify where information gets lost.
Clean the underlying data.
Automate one handoff.
Measure the result.
Then move to the next workflow.
This is far more manageable than launching a massive “Digital Transformation Program” and hoping the technology eventually delivers value.
The Real Meaning of Digital Thread
The Digital Thread isn’t really about software. It is about continuity of information. When engineering creates something, the information should remain useful as it moves through purchasing, manufacturing, quality and eventually the customer lifecycle.
For an SMB manufacturer, that can mean fewer spreadsheets, fewer manual handoffs, fewer conflicting BOMs, better traceability and less dependence on individual people’s memory.
And that’s why the Digital Thread is becoming an important foundation for Industry 5.0.
Because the smart factory isn’t simply the factory with the most technology. It is the factory where people, processes, products and data stay connected.
The goal isn’t to connect everything.
The goal is to stop important information from getting lost between the things you already have.
Start with where your data breaks. Fix that first. Then automate.
