Your IT department manages critical systems, runs transformation projects, arbitrates tight budgets. It knows where the risks are, it has dashboards. And yet there's a blind spot in its map. Not through negligence, but because of the nature of the problem: a fragmented bill of materials doesn't trigger an alert. It doesn't cause a visible incident. It costs silently, through eroded margins, unexplained delays, audits that go off the rails.
What a BoM is, and why it's too often fragmented
A Bill of Materials is a product's full nomenclature: every component, every sub-assembly, every material, every associated supplier, with their hierarchical relationships and attributes. In theory, it's the product's DNA. In practice, in nearly every industrial company, this DNA is scattered across several systems that don't talk to each other.
Engineering works on a design BoM in the PLM. Manufacturing builds an adapted version in the MES. Procurement maintains its own lists in a third-party tool or a spreadsheet. And somewhere, there's the senior engineer's file, the one retiring in eighteen months, who is the only person who knows how the versions fit together.
This isn't an accident. It's the natural consequence of organizations that grew their systems by stacking rather than integrating. Each domain has its tools, each tool has its own logic, and the BoM runs through all of it without ever existing in full in one place. IT knows this, broadly. What it doesn't see is what it really costs.
Cost #1: the loss of visibility that paralyzes silently
Ask your business experts how many different versions of a product's BoM currently coexist in your systems. They probably won't know the exact answer. That's not an admission of incompetence: it's the honest answer to a question no system is built to answer.
When engineering changes a component, that change has to propagate to manufacturing, procurement, after-sales, regulatory compliance. In a fragmented system, this propagation is manual, partial, delayed. Downstream teams sometimes work for weeks on a version that's no longer current, without knowing it.
Engineers spend on average 26% of their time searching for information instead of designing. That's more than a full workday a week, lost in fragmented data.
For IT, this problem is invisible because it doesn't generate any system incident. No log flags that a manufacturing team is working on an obsolete BoM. No alert fires when engineering has changed a reference without procurement knowing. What's visible are accumulated delays, unplanned coordination meetings, decisions made on data that no longer reflects reality.
Cost #2: operational risks hidden in the margins
A BoM error isn't just a data problem, it's a production problem. An incorrect part number triggers the wrong component order. An outdated quantity causes an under-supply that stops a line. An unsynchronized version between engineering and manufacturing produces assemblies that don't meet spec.
What IT sees: a production incident, a delivery delay, a stock discrepancy to explain in a committee. What it doesn't see: that the root cause is the fragmentation of the nomenclature, and that it will recur until the reconciliation is done. The risk is systemic: it replays with every modification, every new supplier, every range change. Teams then develop workaround reflexes, manual checks, cross-validations, weekly "BoM meetings", which absorb time and mask the problem without solving it.
Cost #3: the cost explosion no one tracks
The costs of a fragmented BoM appear in no budget. They're diluted into line items that look normal: coordination hours, order corrections, delays absorbed by safety margins. That's exactly what makes them dangerous. A visible cost can be attacked; an invisible cost perpetuates itself.
Poor data quality costs organizations an average of $12.9M a year, and 27% of data in enterprise systems is inaccurate or incomplete at the moment it's used to decide (Gartner).
Here are the line items industrial IT departments consistently underestimate.
A well-structured BoM is the foundation of cost control: it lets you calculate production costs reliably and anticipate supply needs precisely. Its opposite is a machine for producing budget gaps whose origin is never really found.
Cost #4: compliance waiting to strike
This is the most underestimated pain point, and potentially the most costly. RoHS and REACH regulations require documenting the compliance of every component, sub-assembly and material present in the final product, at every level of the nomenclature. Not just electronic components: chassis, cables, adhesives, fasteners, everything that makes up the product must be traced.
A fragmented BoM makes this exercise structurally unreliable, for two reasons. Tracing substances across sub-assembly levels is impossible to guarantee when data is scattered across several systems. And when a supplier changes a component's composition, that change doesn't propagate automatically: non-compliance sets in silently.
The penalties are concrete: fines of up to €100,000 per violation in Europe, product recalls, bans from the European market, lasting reputational damage.
For industrial IT, this risk is insidious because it's deferred. Today's fragmented BoM becomes tomorrow's compliance problem, at the exact moment the company launches a new market, responds to a tender, or gets audited. Good practice, maintaining a nomenclature carrying the compliance status of every part, requires a single, up-to-date BoM spanning all levels. The exact opposite of a fragmented one.
How to make the problem visible to your IT department
Industrial IT isn't blind to these stakes: it's overloaded, with competing priorities and metrics that don't show this level of granularity. To get it to act, you need to show it the problem in its own language.
What Graphicient brings
Graphicient doesn't replace your existing systems. It adds the semantic layer, the bridges that are missing between them.
A fragmented BoM appears in no dashboard, no metric measures it, and that's exactly why it costs so much. Your data exists, and it's correct, each piece in its own system. What doesn't exist is the ability to cross it instantly to answer a simple question: if this component changes tomorrow, what breaks?
