MRO, in the context of asset-intensive businesses is short for Maintenance, Repairs and Operations, which refers to the entirety of maintenance workflows, upkeep and all the managerial and technical tasks that are needed for its successful completion.
In the context of Aviation, MRO is short for Maintenance, Repairs and Overhaul, which refers to the entirety of turning around the flight for its next scheduled travel after completion of the maintenance processes as per protocol.
In some rare cases, MRO is also referred to as “Medical Records Organization” that primarily refers to management of clinical information and data.
The most widely accepted definition though, is Maintenance, Repairs and Operations which is discussed further below in this post.
What Are The Processes in MRO
MRO as a function refers to the entirety of maintenance lifecycle processes and includes but is not limited to;
- Preventive & Predictive Upkeep of Fixed Assets, Repairs and Routine Maintenance
- Reactive repairs of machinery, production lines as and when they break down
- Managing Maintenance Work orders and Maintenance Schedules, manually or digitally
- Gestión de existencias
- Category Management for Sourcing MRO Spares and Equipment
- Managing MRO Master Data pertaining to equipment, spare parts, suppliers and services and ensuring real-time sync and data sanity.
- Analysis of MRO Spends and optimizing them
- Updating ERP & EAM systems with the right information
- Ensuring the right software solutions are in place for Predictive, Preventive and reactive maintenance practices.
Based on the above, one can see that “MRO” is an all-encompassing, broad term that doesn’t just refer to maintenance but also all the managerial, digitization, and governance, compliance and process workflows that enable excellence in maintenance operations.
Industries That Depend on MRO Data
How Does This Benefit Enterprise Supply Chains
For asset-intensive operations, optimizing for enterprise MRO supply chains is a key priority area as it is a significant cost-centre, and if mismanaged, the costs can theoretically balloon limitlessly. For enterprises managing complex operations and high-value assets, MRO can account for up to 10% of total annual spending.
By investing in MRO, enterprises expect at least one among the below-listed benefits and organizations
- Arresting Ballooning Procurement Costs
Effective data management and excellence in predictive and preventive maintenance approaches enables organizations to forecast demand, ensuring proper planning of production facilities, MRO services, MRO spare parts, fixed assets with the right MRO vendors.
- Eliminating (or Minimizing) Downtime
One of the more impactful areas where effective MRO planning can enable companies to predict defects, breakdowns and unavailability, thus ensuring instances linked to production or equipment downtime are minimized.
Availability of reliable data from raw ERP & EAM sources and effective transmission of data from IoT sensors and machines are key to ensuring that downtime minimized/eliminated
- Prevent Maverick Spending
Last minute planning, poor procurement practices and mismanaged of key maintenance processes can directly lead to excessive spending, especially to mitigate issues like unavailability of critical spares.
Maverick Spending is a critical issue in MRO that plagues most enterprises, especially ones with poor data management and predictive maintenance disciplines set in place.
Research shows that typical MRO spend is between 6%-10% of a site’s overall spend, with organizations managing multimillion-dollar annual expenditures for MRO supplies and services
Who Needs to Focus on MRO?
Optimizing MRO spend and vendor management
Streamlining spare parts availability and logistics
Reducing unexpected breakdowns
Maximizing efficiency of fixed assets
Containing costs through better MRO analytics
Embedding predictive technology into MRO workflows
Conclusion: Why Production Supply Chains Must Rethink MRO
MRO in manufacturing and production supply chains is no longer just about buying spare parts or servicing equipment. Today, MRO is a strategic, multidimensional discipline that integrates procurement, planning, asset management, maintenance workflows, and real-time data governance. For modern enterprises, the ability to manage and optimize MRO processes directly translates to:
-
Higher uptime: Reliable, well-maintained assets keep production lines running smoothly and minimize costly disruptions.
-
Lower costs: Strategic MRO sourcing and data-driven spend analysis reduce leakage and unnecessary expenses, keeping budgets under control.
-
Efficient use of resources: Lean inventory management and automated workflows ensure you have the right parts, tools, and skills available-exactly when needed.
-
Stronger compliance and governance: Accurate data and robust process controls help meet regulatory requirements and mitigate supply chain risks.
Organizations that proactively optimize their MRO supply chains build resilience against volatility, reduce waste, and maintain a sustainable competitive edge in fast-moving markets.
Next Steps for Professionals:
By streamlining MRO processes, organizations can take meaningful steps toward eliminating maverick spending, enriching and standardizing MRO master data, and gaining comprehensive visibility within ERP and EAM systems.
Implementing a purpose-built digital MRO solution serves as a cornerstone for these improvements, allowing companies to harness data-driven maintenance strategies, enhance production supply chain efficiency, manage costs proactively, and maximize equipment uptime.
As industries evolve, digital MRO platforms deliver transformative outcomes that position enterprises for long-term resilience and operational excellence.
