What Does MRO Stand For, and Why Does It Matter?

Efficient production is a priority in any industry, and operational continuity depends on well-managed assets. A strong MRO strategy ensures that your teams will have access to essential supplies, equipment, and materials. The ability to grab what you need when you need it reduces downtime and keeps your operations productive. Proactive MRO inventory management gives you a competitive advantage — letting your organization get the most out of your assets while streamlining maintenance processes and improving overall operational efficiency.

What Does MRO Stand For?

Maintenance, repair, and operations (MRO) refers to supplies and materials that impact facility operations but aren’t usually a direct component of the end product. Two common examples of MRO supplies include spare parts for production equipment or cleaning supplies for janitorial services. While these are two instances familiar to most organizations, MRO products cover a wide range of materials and supplies for a variety of purposes.

Why is MRO Important?

MRO has a significant impact on supply chains and line efficiency. The longer you have to wait for critical components like equipment parts, the greater the delay in delivering your product or service to your customers. Having a vital tool or critical spare part on hand can make the difference between a quick turnaround and being forced to wait.

What is Included in MRO?

Essential maintenance supplies and vital replacement parts vary by business. However, most industries share common categories of MRO materials. Here are some common categories of MRO supplies that many organizations use:

• Janitorial supplies help keep interior spaces clean and clutter-free. Examples include industrial cleaners, sanitizing solutions, mops, and brooms.
• Office supplies are necessary for performing office-related work. Examples include computers, paper, paper clips, and pens.
• Personal protective equipment (PPE) items are designed to protect workers from injury while doing their jobs. Examples include protective gloves, respirators, face shields, and earplugs.
• Testing supplies are used to validate and verify products and materials. Examples include test tubes, scales, centrifuges, and beakers for laboratory testing. 
• Spare parts are easy-to-store replacement components that facilities often keep on hand. Examples include bearings, spare motors, and gears.
• Maintenance supplies are materials used in equipment and facility upkeep. Examples include lubricants, nuts and bolts, filters, and valve seals.

The Role of MRO in Supply Chain Management

Maintenance teams often face critical events they must address to restore normal operations. Integrating a strong MRO plan into your broader maintenance strategy gives your team what they need to avoid disruptions and minimize downtime. A well-structured MRO plan prevents disruptions while helping you maintain seamless workflows, efficient workforce management, and optimized production schedules. An MRO inventory management software solution helps maintenance professionals ensure supplies are ready when needed.

Inventory Management

Proper MRO inventory management keeps essential supplies in stock by tracking current store levels and replenishing depleted items. Without a proper tracking system, businesses could easily over-purchase supplies, which leads to wasted resources, or under-stock essential components, which can delay critical maintenance. Waiting for a vital tool or spare part can reduce production and cut potential revenues, and a strong inventory management system ensures you always have the right MRO products on hand. 

MRO Procurement

MRO procurement is the process of acquiring the materials necessary for maintaining a facility, repairing production equipment, and continuing operations. Reliable enterprise asset management (EAM) minimizes storage by anticipating your MRO needs, enabling you to order ahead when the time comes. Businesses in industries with high equipment turnover, like manufacturing and logistics, often use EAM systems to predict and manage MRO inventory needs and prevent supply chain disruptions. These systems ensure you only need to keep the most vital and frequently used MRO supplies in stock, reducing unnecessary storage.

Vendor Relationships

Many organizations find it more practical to go through a vendor-managed inventory (VMI) firm to track and resupply MRO necessities for budgetary, staffing, and space-related reasons. With VMI, the vendor manages the stock levels and resupply decisions for the client company’s MRO materials. Vendor-managed inventory relieves the company of most tasks involving storage systems and supplier management, allowing it to focus on other vital matters.

Supply Chain Optimization

MRO supply chain optimization maximizes efficiency by tracking and refining each step in the supply chain. Specialized staff or vendors identify production line pain points and logistical bottlenecks to address immediate issues and create more efficient processes. Improving methods at every step of the production process creates a smooth product flow to end-users and minimizes delivery delays.

What Does MRO Stand for in Manufacturing?

In manufacturing, MRO refers to the essential supplies, tools, and services that keep production lines running smoothly. While MRO items aren’t part of the final manufactured product, they are very important for making sure your equipment is reliable and you experience minimal downtime.

MRO in manufacturing typically includes:

• Production Equipment Repair: This includes spare parts, lubricants, and tools that keep your machines running smoothly.
• Preventive Maintenance Supplies: These items are typically filters, cleaning agents, and calibration tools to help you avoid unexpected equipment failures.
• Safety Equipment: PPE, fire suppression systems, and emergency lighting safeguard against hazards and maintain a safe environment for your workers.

A well-structured MRO plan reduces the risks of unscheduled equipment downtime, supply chain disruptions, and higher operational costs. Incorporating VMI and EAM systems will help you further streamline MRO procurement so that you always have the materials you need.

Challenges in MRO Management

Manually managing an MRO strategy comes with its own set of challenges, but a reliable maintenance management software solution helps maintenance managers overcome them. Companies relying on paper-based systems struggle to track real-time inventory, leading to forecasting errors and delayed repairs. A cloud-based solution offers live data access, ensuring teams always have the right supplies on hand. Some common MRO management obstacles include: 

• Data Management: Manually searching for paper records often leads to delays and disrupts production.
• Reactive Maintenance Processes: Reactive, run-to-fail maintenance is typically more costly than proactive preventative maintenance. Worn parts can accelerate breakdowns, adding to the repair workload and overall MRO costs.
• Inventory Control: Siloed processes, such as separate parts inventory and routine preventive maintenance operations, can delay maintenance and repair activities as crews wait for spare parts.
• Lack of Visibility: Manual MRO processes make gathering real-time information harder and more time-consuming. Handwritten records can be difficult to read and may lack useful insights. 
• Low Productivity: On average, maintenance personnel spend just 20% of their time doing any actual repairs or maintenance. The rest is lost to travel time, gathering information and tools, and awaiting instructions.

Best Practices in MRO Management

Fine-tuning your maintenance and inventory management processes can significantly reduce unplanned equipment downtime and help control upkeep and repair costs. These best practices can make your MRO strategy more effective: 

• Centralized Procurement Strategy: Keeping MRO data and procurement processes in one place makes tracking easier and improves coordination with vendors. A centralized approach ensures that all essential parties stay informed of statuses, maintenance records, and current needs.
• Procurement Software Solution: Including procurement software in your MRO management strategy helps prevent duplicate work orders, avoid overstocking, and keep essential materials on hand. Advanced analytics take the guesswork out of supply planning.
• Tracking Vendor Performance: Monitor the timeliness of material deliveries and the effectiveness of VMI providers. Keeping an eye on supplier performance helps vendors meet expectations. 
• Technology and Automation: Enterprise asset management (EAM) software streamlines MRO tracking and resupply, while automated alerts inform managers of low inventory levels. Some systems can even place orders automatically when supplies are running low.
