What is Breakdown Maintenance?
Breakdown maintenance, also referred to as reactive maintenance or run-to-failure maintenance, is a maintenance strategy where assets are allowed to operate until they fail. Repair or replacement occurs only after a breakdown happens. This approach contrasts with preventive, predictive, and proactive maintenance strategies that aim to prevent failures before they occur. Historically, breakdown maintenance was the default approach, especially for non-critical assets or in situations where the cost of preventive maintenance outweighed the cost of potential failures.
While breakdown maintenance might seem like a haphazard approach, it can be a viable strategy under specific circumstances. These circumstances typically involve assets that are inexpensive to repair or replace, have a low criticality rating, or whose failure does not significantly impact operations or safety. It is crucial to perform a cost-benefit analysis to determine if breakdown maintenance is the most economical approach for a particular asset. This involves comparing the cost of implementing preventive maintenance with the potential costs associated with asset downtime, repair expenses, and potential secondary damage from failures.
Breakdown maintenance plays a critical role in the broader context of maintenance management. Understanding its limitations and appropriate applications allows maintenance teams to allocate resources effectively and optimize maintenance schedules. When strategically implemented, it can minimize unnecessary maintenance costs while focusing preventive and predictive efforts on more critical assets. It is often a component of a mixed maintenance strategy.
A CMMS system can support breakdown maintenance by providing a centralized platform for tracking asset failures, managing repair work orders, and analyzing failure data to identify trends and optimize maintenance strategies. The CMMS facilitates the creation of work orders when a breakdown occurs, tracks the time and resources required for repair, and maintains a history of asset failures. This data helps inform future maintenance decisions and can be used to identify assets that are prone to failure and may benefit from a different maintenance approach. Leveraging CMMS features for breakdown maintenance allows for better documentation, analysis, and informed decision-making.

Why is Breakdown Maintenance Important?
While seemingly counterintuitive, breakdown maintenance remains relevant in certain situations. Its primary benefit lies in its simplicity and minimal upfront costs. No scheduled inspections, lubrication, or component replacements are performed unless a failure occurs. This reduces the workload on maintenance staff and minimizes the need for extensive maintenance planning and scheduling.
Breakdown maintenance can be cost-effective for assets with low criticality, meaning their failure does not significantly impact production, safety, or the environment. For example, a non-essential light fixture in a storage room might be a suitable candidate for breakdown maintenance. The cost of replacing the bulb after it burns out is likely much lower than the cost of implementing a preventive maintenance program for all light fixtures. Furthermore, assets with inherent redundancy may tolerate a run-to-failure strategy. If a backup system is in place, the failure of the primary system might not cause any downtime, making reactive repairs an acceptable approach.
However, it's crucial to underscore the risks associated with breakdown maintenance. Unplanned downtime can disrupt operations, potentially leading to lost production, missed deadlines, and increased costs. The failure of one component can sometimes trigger a cascade of failures, causing further damage and requiring more extensive repairs. Moreover, breakdown maintenance can compromise safety if the failed asset poses a hazard to personnel or the environment. Therefore, a careful assessment of risk and criticality is essential before adopting a breakdown maintenance strategy. Using a CMMS to track failure rates and downtime can aid in making informed decisions about when breakdown maintenance is appropriate.
Breakdown Maintenance Best Practices
While breakdown maintenance is a reactive approach, there are best practices that can optimize its effectiveness and minimize its negative impacts. Firstly, conduct a thorough criticality assessment of all assets to identify those that are suitable candidates for breakdown maintenance. This assessment should consider the impact of asset failure on production, safety, the environment, and overall business operations. Only assets with low criticality should be considered for breakdown maintenance. Secondly, maintain accurate and up-to-date asset records, including asset specifications, maintenance history, and failure data. This information is essential for diagnosing failures, planning repairs, and tracking maintenance costs. The use of a CMMS is crucial for managing asset records effectively.
Thirdly, establish clear procedures for reporting and responding to breakdowns. This includes defining roles and responsibilities, setting response time targets, and ensuring that maintenance staff are adequately trained to diagnose and repair failures quickly and efficiently. Fourthly, maintain an adequate inventory of spare parts for critical assets that are subject to breakdown maintenance. This reduces delays in the repair process and minimizes downtime. Regularly review and update the spare parts inventory based on failure data and usage patterns. Fifthly, document all maintenance activities, including the date and time of the repair, the nature of the problem, the parts used, and the time spent on the repair. This data is essential for tracking maintenance costs, identifying trends, and evaluating the effectiveness of the maintenance strategy. This information should be logged directly into a CMMS.
Sixthly, regularly analyze failure data to identify recurring problems and opportunities for improvement. This may involve conducting root cause analysis to determine the underlying causes of failures and implementing corrective actions to prevent future occurrences. Finally, consider implementing condition monitoring techniques for assets that are subject to breakdown maintenance but have a potential for catastrophic failure. Condition monitoring can provide early warning of impending failures, allowing for proactive intervention and preventing costly downtime. Vibration analysis, infrared thermography, and oil analysis are examples of condition monitoring techniques.

Implementation Guide
Identify Asset Failure
Recognize the asset malfunction through operator reports, automated alerts, or routine inspections. Document the date, time, and nature of the failure for future analysis.
Create Work Order
Generate a detailed work order within the CMMS specifying the affected asset, problem description, required tasks, and necessary parts. Assign the work order to a qualified technician.
Diagnose and Repair
Technicians diagnose the root cause of the failure, procure necessary parts, and perform repairs according to the work order instructions. Follow safety protocols and document all steps taken.
Test and Validate
After repairs, thoroughly test the asset to ensure it functions correctly and meets operational requirements. Validate that the root cause has been addressed and the failure is resolved.
Close Work Order and Document
Close the work order in the CMMS, recording all repair details, parts used, time spent, and any relevant observations. This information is crucial for tracking maintenance costs and identifying trends.
