What is Reactive Maintenance?
Reactive maintenance is the process of repairing equipment only after a failure, often described as breakdown maintenance or “run-to-failure.” This approach centers on swiftly restoring assets to operational conditions, focusing on immediate repair actions.
Imagine a busy factory floor where every machine contributes to production targets. Abruptly, a crucial machine stops working. This incident disrupted production schedules and threatened to miss deadlines. How does the company respond? The immediate solution is reactive maintenance.
This guide explores the critical aspects of reactive maintenance, emphasizing its importance, challenges, and tools that make this difficult task more manageable for production planners.
What is Reactive Maintenance?
Reactive maintenance is a maintenance strategy that focuses on repairing or replacing equipment after a failure occurs. This approach involves waiting for machinery to break down before taking action.
Reactive maintenance aims to restore the equipment to its operational state as quickly as possible, minimizing downtime and ensuring production can resume promptly.
However, as a whole, reactive maintenance is often seen more as a temporary remedy rather than a sustainable strategy. It contrasts with predictive maintenance, responsive maintenance, or scheduled maintenance, which are proactive approaches.
Responsive maintenance, situated between reactive and predictive approaches, involves monitoring the condition of machinery and responding swiftly to early signs of deterioration, not just waiting for a complete breakdown.
This proactive stance allows for timely interventions that can prevent the progression of minor issues into major failures.
Predictive maintenance employs data analysis and predictive analytics to foresee equipment malfunctions before they occur, enabling proactive measures. Scheduled maintenance, on the other hand, involves regular, planned checks and repairs to prevent unexpected breakdowns.
While reactive maintenance addresses issues as they arise, responsive, predictive, and scheduled maintenance aims to avoid them altogether, promoting a more consistent and reliable production process.
Types of Reactive Maintenance
Reactive maintenance, a strategy employed when dealing with equipment failures, can be broadly categorized into corrective and emergency maintenance. Each serves a specific purpose within the maintenance spectrum, addressing issues at different levels of urgency and planning.
Corrective maintenance refers to any maintenance task that rectifies and repairs faults in machinery or equipment. This type of maintenance is reactive, as it occurs after an issue has been detected or a failure has happened. It involves restoring the equipment to its proper operational condition.
While corrective maintenance is often unplanned, it can sometimes be scheduled following routine inspections or performance monitoring, where issues are identified before leading to a complete breakdown.
On the other hand, emergency maintenance is a more critical form of reactive maintenance. It’s necessitated by unexpected, severe problems that demand immediate attention to prevent hazardous situations, significant operational disruptions, or substantial financial loss.
Emergency maintenance is characterized by urgency and high priority, often requiring swift action to mitigate risks and restore safety and functionality to the affected systems. Despite being a subset of reactive maintenance, the pressing nature of emergency maintenance distinguishes it, emphasizing the need for rapid response and resolution.
Example of Reactive Maintenance
Consider a local bakery that relies on an industrial oven to bake bread and pastries. One busy morning, without warning, the oven suddenly stops heating. The bakery staff can not bake any products until the oven is fixed. The bakery manager immediately calls a technician to diagnose and fix the problem.
The technician arrives, identifies a faulty heating element, replaces it, and the oven is back in operation after a few hours. This approach, where the bakery waited for the oven to break down completely and then took action to repair it, is an example of reactive maintenance.

Problems Reactive Maintenance Aims to Solve
When a machine on a workstation or tool stops working, it can lead to problems, affecting not just the production line but the business as a whole. Reactive maintenance steps in to solve these issues:
- Production Downtime: The most immediate problem is the halt in production. Reactive maintenance aims to get the equipment up and running as quickly as possible to minimize the time the production line is inactive.
- Cost Escalation: Unexpected machine breakdowns can lead to rushed repair jobs, often at a premium cost. Reactive maintenance focuses on fixing the problem efficiently to avoid excessive costs.
- Quality Control Issues: When machines don’t operate correctly, the quality of the products can suffer. Reactive maintenance ensures that any machinery that might compromise product quality receives immediate attention.
- Safety Risks: Malfunctioning equipment can pose safety risks to the staff. Through reactive maintenance, such equipment is promptly repaired, ensuring the safety of the workforce.
- Resource Misallocation: A broken machine might require reallocating staff or other resources to different tasks, disrupting the planned workflow. Reactive maintenance seeks to limit this disruption by restoring normal operations swiftly.
- Customer Satisfaction: Production delays can lead to missed deadlines and a failure to meet customer demands, potentially harming the company’s reputation. Reactive maintenance helps mitigate these risks by ensuring production can resume quickly after a breakdown.
While reactive maintenance is crucial for addressing immediate issues, integrating it with advanced planning tools like APS systems can significantly enhance its effectiveness, creating a more robust and responsive maintenance strategy.
The Role of APS in Enhancing Reactive Maintenance
Advanced Planning and Scheduling Software (APS) systems are pivotal in elevating the efficiency and effectiveness of reactive maintenance, empowering production planners to meet their deadlines despite unexpected equipment breakdowns.
Here’s how an APS system like Skyplanner, can transform the reactive maintenance process:
Real-time Monitoring and Alerts
- Detailed Breakdown Analysis: Besides alerts, APS provides detailed insights into the nature of the breakdown, aiding maintenance teams in preparing adequately before they even approach the machine, thus speeding up the repair process.
Efficient Resource Allocation
- Dynamic Rescheduling: While manual planning or spreadsheet-based methods find it challenging to adapt to the rapid pace of change, an APS like Skyplanner excels.
It can swiftly reevaluate and adjust the production schedule in case of a machine breakdown.
In the case of Skyplanner, with the simple click of the “King button,” it performs this dynamic rescheduling in real-time with the help of AI, a feat unattainable with traditional, manual approaches or Excel production planning.
This capability ensures that other operations proceed with minimal disruption, significantly mitigating the impact of downtime and maintaining the rhythm of your production flow. - Optimal Resource Redistribution: APS systems can guide the redistribution of resources, whether reallocating staff to different tasks or rerouting production through alternative machinery or workstations, ensuring that every possible measure is taken to adhere to the original production deadlines.
Improved Communication and Coordination
- Enhanced Collaboration: APS platforms facilitate communication between departments. Production planners, maintenance teams, and floor managers can stay in constant sync, ensuring everyone is aware of the schedule changes and maintenance activities, leading to a more coordinated approach to problem-solving.
By integrating reactive maintenance with an Advanced Planning and Scheduling system like Skyplanner, production planners gain a powerful ally in maintaining production efficiency and meeting deadlines.
This integration addresses the immediate challenges of machine breakdowns and paves the way for a more informed, data-driven approach to maintenance and production planning.
