What Gets Measured Gets Done: Data Quality Accountability for Supply Chain Leaders

A quick test for your next supply chain review: can you state your material master's current duplication rate as readily as you can state your inventory turns — and if that rate rose this quarter, would anyone in the room know? For most supply chain leaders in asset-intensive industries, the honest answer is no. Procurement savings have an owner and a number. Stock availability has an owner and a number. DIFOT has an owner and a number. The data quality that quietly shapes all three has neither — which is precisely why, year after year, it never improves.

Two of the oldest laws of management apply here with full force: what is not measured does not improve, and what nobody owns, nobody does. Material master data has spent decades exempt from both laws, filed away as an IT hygiene matter below the management radar. The supply chain organisations now breaking that pattern are doing something disarmingly simple — giving data quality a number, an owner and a seat in the monthly review. And the reason so many are doing it now is worth a closer look.

The AI Rush Is Exposing an Old Accountability Gap in Supply Chain

Consider what has changed in executive agendas over the past two years. Nearly every supply chain function in mining, oil and gas, energy and manufacturing is under instruction to adopt AI — spend analytics, demand forecasting, intelligent procurement, inventory optimisation. And nearly every one of those initiatives has hit the same wall: executive surveys and analyst commentary across this period have repeatedly identified data quality as the leading barrier to moving AI beyond the pilot phase. Spend analytics built on inconsistent classifications mis-categorise millions in procurement. Forecasting tools inherit demand histories fragmented across duplicate item numbers. Optimisation engines recommend buying parts the warehouse already holds under a different record.

The significance of this development is not the technology — it is the accountability shock, and it lands squarely on the supply chain leader's desk. For years, poor material master data imposed its costs diffusely: a duplicate purchase here, a slow search there — losses real but scattered enough that no single executive felt them. AI initiatives concentrate those scattered costs into one visible failure that the entire leadership team watches. Suddenly the question "who owns our data quality?" is being asked in rooms where it was never asked before, and every eye turns toward the function that owns procurement, inventory and the material master's daily use.

The implication is direct: supply chain leaders who respond by building a genuine accountability system — metrics, owner, review rhythm — will convert the AI pressure into a permanently healthier material master. Those who respond with a one-off clean-up will be standing at the same wall in two years.

Why Data Quality Never Improves Without an Owner and a Number

The two management laws bite hard on this problem because of how material master data actually degrades: through thousands of small, individually rational decisions. A storeperson creates a duplicate record under time pressure. A buyer accepts a vague description to push an urgent purchase order through. A site adopts its own abbreviations because agreeing a standard felt slow. No single decision is worth escalating; collectively they compound into the 10–20 per cent duplication rates and patchy descriptions that professional assessments routinely uncover.

Against a problem with that structure, good intentions are powerless. An unowned metric lets every department assume someone else is watching; an unmeasured problem means even the people who care cannot demonstrate whether things are improving or decaying. This is why data initiatives so often follow the same arc — a burst of cleansing activity, a genuinely improved dataset, then a slow relapse as the thousand small decisions resume, unmeasured and unowned. The dataset was fixed; the accountability system was never built.

The fix is not cultural exhortation, and it is not a bigger project. It is the same mechanism supply chain leadership already applies to everything it takes seriously: a small set of numbers, one accountable name, and a recurring slot in the review calendar. Data quality changes its fate on the day it earns a seat in the monthly meeting.

Choosing the Few Metrics That Matter

The first design decision is also the first trap. Data quality can be measured forty different ways, and a forty-number dashboard is how the topic gets ignored with extra steps — nobody reads it, nobody is accountable for any single figure, and the review slot dies of boredom within a quarter. The discipline is to choose a handful of metrics that a supply chain leadership team can genuinely interrogate. Four cover the material master well for most organisations.

Duplication rate. The percentage of item records that duplicate another identity of the same physical part. This is the headline number because it drives the costs supply chain already feels — duplicate purchases, fragmented demand history, working capital stranded on shelves. It is measured on the stock of records, so it reflects the accumulated past.

Description completeness. The share of items whose descriptions carry the mandatory attributes for their class — enough for a planner or buyer to identify the part without opening a second system or phoning the site. Completeness is what makes a catalogue usable rather than merely populated.

Classification coverage. The proportion of items correctly classified to the agreed standard, whether UNSPSC or NATO codification. Classification is the quiet enabler behind spend analysis, category management and search; when coverage is patchy, every downstream procurement report inherits the gaps.

New-item compliance. The percentage of newly created records that pass the quality gate first time — duplicate check performed, naming convention followed, classification assigned. This is the leading indicator in the set: the first three metrics describe the state of the stock, but this one describes the flow, and it predicts whether the others will improve or relapse. A leadership team that watches only the stock metrics will congratulate itself on a clean-up right up until the relapse shows.

Four numbers, one page, trends over time. Anything the review cannot discuss in ten minutes does not belong in the pack.

Owning the Numbers: Why the Mandate Belongs in Supply Chain

A metric without an owner is a screensaver. The second design decision — who owns these numbers — determines whether the system has teeth, and for once the answer is not a debate. The instinct to hand data quality to IT feels natural because data lives in systems, but the causes of degradation (uncontrolled item creation, unagreed standards, site habits) and the consequences (procurement cost, stock availability, working capital) both live in your function. An IT owner can report the numbers. Only a supply chain owner can move them.

In practice that means the accountability sits with you or your direct report — typically supported by a working-level data steward who runs the operational cadence. What matters more than the title is the mandate, and it needs three specific powers: the authority to enforce the item-creation quality gate across all sites, including the power to reject non-compliant requests; a budget line for remediation, so improvement does not depend on begging other functions; and the standing to bring the four metrics into the monthly review as a first-class agenda item. Strip any one of the three away, and ownership collapses back into observation — someone watching the numbers decline with formal responsibility and no levers.

The rhythm question resolves just as cleanly. Resist the well-intentioned mistake of a separate "data governance committee" — a new meeting, attended by delegates, decaying within six months. Place the four metrics inside a review that already exists and already commands attendance: the monthly S&OP or supply chain performance meeting, wherever availability and procurement cost are already discussed. Ten minutes, one page, the same discipline as every other KPI.

Where a Cataloguing Partner Fits: Baseline, Remediation, and a System That Holds

Here is the practical obstacle most supply chain leaders hit next: the accountability system needs an honest baseline and a credible remediation path, and neither is a spreadsheet exercise. Measuring true duplication requires distinguishing genuinely identical parts hiding behind different descriptions from genuinely different parts hiding behind similar ones — judgement work that demands cataloguing expertise, not text matching. This is precisely what a professional cataloguing engagement delivers, and why many organisations start their accountability journey with one.

A well-run engagement maps directly onto the system described above. It begins with a data assessment that produces your first real numbers — measured duplication, completeness and classification coverage on your actual data, giving the monthly review an evidence-based starting point instead of a guess. Remediation follows in priority order: experienced cataloguers consolidating duplicates through specification analysis, rewriting names and descriptions to a consistent noun-modifier convention, and classifying items to the agreed standard — supported by purpose-built tooling such as SCS for the cleansing, naming, describing and classification work, always under the cataloguers' judgement rather than in place of it. And critically, the deliverables extend beyond clean data: documented naming standards, a designed item-creation quality gate, and governance recommendations — the very machinery your new-item compliance metric will measure. A partner engaged this way is not replacing your accountability system; it is installing the foundations that let the system run.

One caution as the rhythm beds in: expect the numbers to get worse before they get better, and say so in advance. The first honest baseline almost always reveals more duplication and less completeness than anyone assumed, and an unprepared executive team can mistake honest measurement for sudden failure. The owner's first job is to frame the baseline as the starting line, not the scandal.

Conclusion

Material master data quality does not improve through awareness campaigns, clean-up projects or better intentions, because none of those changes the structure that lets it degrade: no number, no owner, no rhythm. The supply chain leaders getting this right — increasingly under pressure from AI initiatives that punish bad data in public — are applying the oldest management mechanism there is. Four metrics that fit on a page. One accountable owner inside supply chain, with a real mandate. Ten minutes in a monthly meeting that already exists.

It is unglamorous, and that is rather the point. What gets measured gets done; what gets owned gets fixed; and what gets reviewed every month stays fixed. Data quality changes its fate on the day it earns a seat at your table — everything before that day is a project, and everything after it is a system.

Get Your Baseline Before Your Next Monthly Review

Before assigning owners and building the metrics pack, there is a prior question worth answering: do you actually know today's numbers — your real duplication rate, your real description completeness?

Because while the baseline stays unknown, the costs keep running unmeasured. Procurement keeps buying parts that already sit on a shelf under another number. Inventory visibility stays clouded. Working capital stays locked on the racks, and your planners keep spending their hours hunting for information instead of making decisions.

In most organisations, the obstacle is not the ERP, and it is not the team. It is the quality, governance and searchability of the material master data underneath — inconsistent descriptions, unreliable classifications, and numbers nobody has ever formally measured.

That is why at Panemu, we help supply chain organisations establish the true condition of their material master data through a free consultation and data assessment — measuring duplication, completeness and classification coverage on your actual data, and providing practical recommendations for a stronger procurement, inventory and supply chain foundation.

Because an accountability system can only start from an honest baseline.
