Companies, having everything under control does not mean controlling everything
An uncomfortable question
Who touched this part, when, and with what outcome?
Exteryo Report Editorial Team
Identification, serialisation, tracking and security: the four levels of industrial control, and why skipping one takes value away from the project.
The short answer
Having everything under control means being able to say, for every relevant object, who touched it, when and with what outcome.
The short answer
To get there, three things are needed:
- Identitya digital identity for the object
- Eventan event recorded at the moment it happens
- Actiona collection action simple enough to actually be done
The short answer
Underneath there are four levels: identification, serialisation, tracking and security.
Why it is not simple
Claiming to have processes under control is easy.
Proving it? No.
Why it is not simple
Then comes the audit, or a return, or a line stoppage. If the answer requires a phone call, an Excel file and half a day of reconstruction, the control was not there.

What is being controlled, if not people?
Objects, not people
The control we are talking about does not concern people: it concerns objects, processes and events.
Objects, not people
It means that every relevant asset, a garment, a PPE, a machine, a pallet, a street lamp, has a digital identity. Every event concerning it is recorded at the moment it happens, not after the fact.

Note
A phone call, an Excel file and half a day: that is the cost of data reconstructed afterwards.

What are the four levels of control?
In layers
Control is built in layers, and each layer enables the next.
The four levels
- Identificationthe object is distinguishable from all others, even from identical ones
- Serialisationthat identifier corresponds to a record, with master data, history and documents
- Trackingmovements and events accumulate on that record over time
- Securitythe identifier cannot be cloned, the record cannot be altered, access is governed
Before moving on
A tracking system based on duplicable identifiers: which level is missing?
In layers
Skipping a level takes value away from the entire project.
In layers
A tracking system built on duplicable identifiers produces data that no one will use to make a decision, because no one trusts it.
Note
The order matters: tracking accumulates events on a record, and the record only exists if the object has first been identified and serialised.

Where does it usually break?
The last metre
The breaking point is often not the technology: it is the last metre.
The last metre
It is the moment when an operator, wearing gloves, in a cold warehouse, has to record something.

More than a few seconds
The last metre
If that action takes more than a few seconds, or requires a dedicated device they do not have with them, it will not be done.
The last metre
It will be done later, from memory, or it will not be done at all.
The choice is not neutral
An NFC tag read with the smartphone that the operator already has in their pocket has a different adoption rate than a UHF reader that must be picked up from the trolley.
The choice is not neutral
They answer two different questions:
- NFC taga specific object
- UHF readera set of objects in transit
Note
It will be done later, from memory: this is exactly the reconstructed data from the first chapter.

What to ask yourself before buying anything?
Three questions
Before evaluating tags, readers or platforms, three questions are needed.
Three questions
- The decisionWhat decision do I want to make with the data I collect?
- The actionWho performs the action of collecting, and in what physical conditions?
- The errorWhat happens if the data is missing, or is wrong?
Three questions
If there is no downstream decision, the data is a cost.
The question about security
What happens if the data is missing, or is wrong?
Three questions
The answer tells you how robust the security level needs to be.
An assembly
A control project that starts from these three questions almost always arrives at a combination of hardware and software, not a single product.
Note
Exteryo was born as a multicommerce B2B platform because the right answer is almost always an assembly: it is worth knowing this while reading these questions.
In one sentence
Having everything under control doesn't mean controlling everything: it means knowing who touched this part, when, and with what outcome.
