key takeaways
If you only read 30 seconds of this article:
- Your MRO supply chain is not just a background function. For most enterprise manufacturers, it is a blind spot.
- The usual causes: multiple ERPs with no cross-system view, excess stock, fire-drill buying, no standard criticality across plants.
- The answer is not a new ERP. It is a unified layer that connects and analyzes all MRO material data, regardless of system, site or format.
- Standardizing parts criticality is the most overlooked lever: it protects critical spares and stops overstocking of low-impact items.
What's broken in today's MRO supply chains
Despite managing billions in assets, many industrial supply chains still operate in the dark when it comes to MRO. The core problems:
- Multiple ERPs with no cross-system visibility
- Redundant or excess inventory tied up in working capital
- Procurement driven by fire drills, not forecasting
- Decentralized processes with zero standardization
- No clear parts criticality framework across plants
These inefficiencies don't just bloat inventory; they create downtime risk. A single stockout on a critical spare can shut down a $10M production line. And when every plant does its own thing, procurement teams are forced to navigate multiple vendor contracts, inconsistent data, and competing priorities.
The financial impact of MRO supply chain inefficiencies
Let's make it real. Consider a manufacturer with $100M in MRO inventory. Just 10% in excess means $10M locked up in unnecessary stock, money that could be freed up for capital projects or margin protection.
Add to that the 20-25% annual carrying cost (storage, insurance, obsolescence), and you're burning $2-2.5M every year on stock you may never use.
And then there's downtime. One unplanned outage can cost $10,000 to $250,000 per hour, depending on the asset. If that outage was caused by a missing part you actually had in another plant, the cost isn't just operational; it's reputational.

Reactive vs optimized MRO supply chains
| Reactive MRO supply chain | Optimized MRO supply chain | |
|---|---|---|
| Visibility | Each plant sees only its own system | One view of every material across sites and ERPs |
| Stocking | Overstock out of fear, or understock on poor data | Min/max set by criticality, lead time and usage |
| Buying | Emergency orders and fire drills | Transfers first, planned purchases second |
| Suppliers | Many contracts, inconsistent terms | Consolidated vendors, better compliance |
| Teams | Procurement, maintenance and IT measured separately | Shared data and shared priorities |
From chaos to control: the AI advantage
Forward-thinking teams are rethinking their MRO supply chain strategy around one key principle: visibility. That doesn't mean a new ERP. It means a unified layer that connects and analyzes all MRO material data, regardless of system, site, or format.
AI-driven material management platforms ingest "as-is" data from SAP, Oracle, Maximo, Infor and more. The result: centralized visibility, harmonized data, and predictive insights. With this in place, manufacturers can:
- Identify and eliminate duplicate SKUs (duplicate material identification)
- Shift from reactive to predictive stocking (MRO inventory optimization)
- Consolidate vendors and boost compliance (spend analysis)
- Optimize procurement and carrying costs
- Create a unified source of truth across sites and functions (material search)
This is how you build resilience into your operations, without a massive ERP overhaul.
Standardizing parts criticality: a hidden accelerator
One of the most overlooked levers in MRO strategy is parts criticality. Without a standardized, cross-site methodology to rank part importance, most teams either overstock out of fear or understock based on poor data.
AI platforms can help manufacturers define and apply criticality scores across their network, so stocking policies match actual asset impact. This means:
- Critical spares are protected first
- Low-impact items aren't overstocked unnecessarily
- Maintenance teams trust the system instead of hoarding parts
It also improves cross-functional collaboration: procurement knows which parts must be prioritized, and finance understands which inventory is truly strategic. See spare parts criticality and how to run a critical spares assessment.
Case study: global gold mining leader
One of the world's largest gold mining companies, operating across six mines, faced a complex MRO challenge. Disconnected systems, excess inventory, and no standardized approach to parts criticality left millions stranded in working capital.
They needed to:
- Identify and burn down overmax inventory positions
- Standardize parts criticality methodology
- Unify visibility across systems and mines
After implementing Verusen's AI-powered MRO optimization platform:
- They launched material de-duplication and stocking policy optimization across all mines
- Enabled network-level optimization and parts pooling, avoiding unnecessary purchases (spare parts sharing)
- Gained visibility across disparate data sets without cleansing
Impact:
- $96.8M in MRO inventory savings opportunities identified
- $40.1M in immediate Year 1 cash savings through inventory burndown and spend avoidance
- $50.5M from stocking policy improvements, $19.4M from network optimization, $3.9M from material de-duplication
- Significant reduction in risk of stockouts, with optimized policies across the entire network
And most importantly, the company saw these results beginning within the first 90 days.
Beyond inventory: aligning procurement, operations and IT
A modern MRO supply chain strategy isn't just about parts. It's about people, processes, and platforms. Many breakdowns happen because these functions operate in silos:
- Procurement is measured on cost savings
- Maintenance is measured on uptime
- IT is buried in system integrations
When AI platforms unify data, they also unify objectives. Now everyone works from the same playbook:
- Maintenance sees where critical parts are available
- Procurement sees supplier compliance and pricing trends
- IT doesn't have to manually clean and reconcile data
This alignment is what turns cost savings into sustained operational performance.
Where to start
Just getting started? You don't need a data team or a cleanse project. Start with one region or a handful of plants and the ERP data you have today. Talk to an MRO expert.
Running a multi-ERP network already? Look for the network layer: duplicates and transfers across every instance, criticality kept current, and approved changes that write back. See how platforms compare.
Verusen helps Fortune 1000 manufacturers unify MRO data, reduce inventory costs, and avoid stockouts, without replacing their ERP. Book a custom inventory optimization assessment and see how your organization compares, or explore the platform.
FAQ
It is managing maintenance, repair and operations parts, including OEM spares, as one network: a single view of every material across sites and systems, stocking set by criticality, and purchasing that uses what you already own before buying new.
You don't need to replace or unify ERPs. AI can ingest "as-is" data from SAP, Oracle, Maximo, and others to create a single, accurate view of MRO materials.
Many manufacturers see impact in under 60 days as AI uncovers duplicate materials, stockout risk, and excess inventory opportunities across plants.
Most MRO data is inconsistent or unstructured. AI can normalize and harmonize messy, multi-system data automatically, eliminating the need for a lengthy data cleanse.
No. AI enhances existing workflows by improving visibility, supplier data accuracy, and sourcing decisions without requiring teams to change their tools or processes.
