What is Reactive Maintenance?
Reactive maintenance, also known as breakdown maintenance or run-to-failure maintenance, is a maintenance strategy that involves addressing equipment failures only after they have occurred. It's the most basic approach to maintenance, where no preventative measures are taken, and repairs are initiated solely in response to unexpected breakdowns. Reactive maintenance contrasts with proactive strategies like preventive maintenance and predictive maintenance, which aim to prevent failures before they happen.
Historically, reactive maintenance was the dominant approach to maintenance management, especially in the early days of industrialization. However, as equipment became more complex and downtime more costly, organizations began to explore proactive maintenance strategies. While reactive maintenance has its place in certain situations, it is generally considered a less efficient and more costly approach than proactive maintenance strategies for critical assets.
Reactive maintenance is a critical component of maintenance management because, despite the best efforts at prevention, some failures are inevitable. A well-defined reactive maintenance process ensures that failures are addressed quickly and efficiently, minimizing downtime and associated costs. It's essential to have a system in place for reporting, prioritizing, and resolving equipment failures in a timely manner.
A CMMS system plays a crucial role in managing reactive maintenance. It enables maintenance teams to track equipment failures, create work orders, assign technicians, and monitor repair progress. CMMS software also provides a centralized repository for equipment information, maintenance history, and spare parts inventory, which is essential for efficient reactive maintenance. Furthermore, CMMS reporting capabilities can help identify assets that are frequently undergoing reactive maintenance, indicating potential areas for improvement through preventive or predictive maintenance strategies.
While no specific industry standard mandates Reactive Maintenance, general guidelines within ISO 55000 and similar asset management standards discuss managing risks associated with asset failure, which often involves reactive responses as part of a broader, more proactive approach.

Why is Reactive Maintenance Important?
While often viewed negatively compared to proactive strategies, reactive maintenance remains important for several reasons. Firstly, for certain non-critical assets where the cost of preventive maintenance outweighs the potential cost of failure, a reactive approach can be the most economical option. This is particularly true for assets that are inexpensive to replace or repair and whose failure does not significantly impact operations.
Secondly, even with the best preventive and predictive maintenance programs, unexpected failures can still occur. Reactive maintenance provides a necessary safety net, ensuring that failures are addressed promptly and effectively to minimize downtime and prevent further damage. A well-defined reactive maintenance process can also help to identify the root causes of failures, leading to improvements in asset management and preventive maintenance strategies.
Finally, reactive maintenance can be a starting point for organizations that are new to formal maintenance management. Implementing a basic reactive maintenance system can provide valuable insights into equipment performance, failure patterns, and resource requirements. This information can then be used to develop more sophisticated preventive and predictive maintenance programs. By tracking the costs associated with reactive maintenance, organizations can also build a business case for investing in proactive maintenance strategies.
How Reactive Maintenance Works
The reactive maintenance process typically involves several key steps. First, a failure or malfunction is detected and reported. This can be done by operators, maintenance technicians, or automated monitoring systems. The reported issue is then assessed to determine the severity of the problem and the urgency of the repair.
Next, a work order is created to document the failure and initiate the repair process. The work order should include details such as the asset ID, description of the problem, location of the asset, and any safety precautions that need to be taken. The work order is then assigned to a qualified technician who is responsible for diagnosing the problem and performing the necessary repairs.
The technician will diagnose the cause of the failure, which may involve visual inspection, testing, or data analysis. Once the cause is identified, the technician will perform the necessary repairs, which may include replacing parts, adjusting settings, or performing other corrective actions. After the repairs are completed, the technician will test the asset to ensure that it is functioning properly.
Finally, the work order is closed out, and the maintenance history is updated. This includes recording the date of the repair, the parts used, the labor hours expended, and any other relevant information. The maintenance history provides valuable data for tracking equipment performance, identifying failure patterns, and improving maintenance strategies. With a CMMS, this entire process can be streamlined, from initial reporting to final documentation.
Integration with CMMS Systems
A CMMS system is essential for effectively managing reactive maintenance. It provides a centralized platform for tracking equipment failures, creating work orders, assigning technicians, and monitoring repair progress. CMMS software also offers features such as inventory management, which helps ensure that spare parts are readily available when needed, reducing downtime during reactive maintenance.
When a failure occurs, a user can quickly create a work order within the CMMS, specifying the asset, problem description, and priority. The CMMS can then automatically assign the work order to a qualified technician based on their skills, availability, and location. The technician can use the CMMS mobile app to access the work order details, record their work progress, and order parts from inventory.
CMMS systems also provide valuable reporting and analytics capabilities. By tracking the frequency and cost of reactive maintenance for different assets, organizations can identify areas where preventive or predictive maintenance strategies may be more cost-effective. CMMS reports can also help to identify the root causes of failures, leading to improvements in equipment design, operating procedures, and maintenance practices.
Furthermore, CMMS integration with other systems, such as Enterprise Resource Planning (ERP) and Building Automation Systems (BAS), can provide a more holistic view of asset performance and maintenance needs. This integration allows for better coordination between different departments and improved decision-making regarding asset management and maintenance strategies. The Repair Tracking Software aspects of a CMMS are critically important to Reactive Maintenance operations.
Reactive Maintenance Best Practices
While reactive maintenance is often seen as a less desirable approach compared to proactive strategies, there are several best practices that can help to minimize its negative impact. Firstly, it's essential to have a well-defined process for reporting and prioritizing equipment failures. This ensures that critical issues are addressed promptly and efficiently.
Secondly, organizations should maintain an adequate inventory of spare parts to minimize downtime during reactive maintenance. The inventory should be based on historical failure data, equipment criticality, and lead times for parts procurement. It's also important to have a system in place for tracking and managing spare parts inventory, such as using a CMMS with Inventory Management Software capabilities.
Thirdly, organizations should invest in training for their maintenance technicians. Technicians should be trained on how to diagnose and repair common equipment failures quickly and effectively. They should also be trained on how to use the CMMS system to record their work progress and order parts from inventory.
Fourthly, it's important to track the costs associated with reactive maintenance. This includes the cost of labor, parts, and downtime. By tracking these costs, organizations can identify areas where preventive or predictive maintenance strategies may be more cost-effective. Regular analysis of Repair Tracking Software data within the CMMS will also enable smarter decisions in the future. Finally, conduct root cause analysis (RCA) for significant failures to prevent recurrence.
