Preventive maintenance reduces the risk of breakdowns, while reactive maintenance is cheaper in the short term but carries greater risks
Preventive maintenance reduces the risk of breakdowns and is more cost-effective in the long run, while reactive maintenance is cheaper in the short term but carries greater risks.
In facility management there are two fundamental maintenance approaches: preventive and reactive maintenance. Both have their advantages and disadvantages, depending on what type of equipment has to be maintained and the environmental conditions under which it is operated.
Preventive maintenance
The aim of preventive maintenance is to extend the lifespan of equipment and prevent breakdowns through regular inspections and maintenance interventions. This strategy follows a predetermined schedule, regardless of whether the machine has failed or not. It has many advantages: it can reduce operating costs, since regularly maintained machines break down less often, so lower expenses can be expected in the longer term. Equipment works more reliably, which reduces disruptions to business processes and contributes to the safety of employees and the environment. By optimising energy use, preventive maintenance can also reduce energy bills and the ecological footprint of operation. Planned maintenance ensures a longer lifespan for the equipment and increases customer satisfaction, as business processes can run without interruption.
Although preventive maintenance has many advantages, its introduction and upkeep involve significant initial costs. Because of the scheduled inspections and repairs, work may be carried out on machines that would not yet require intervention, which periodically demands extra expenditure and resources. Effective implementation also requires well-trained staff and a suitable IT system that ensures proper scheduling and tracking of maintenance work.
Reactive maintenance
By contrast, the essence of reactive maintenance is that intervention only takes place once a piece of equipment has already failed. In the short term this approach can reduce maintenance costs, as there is no need to spend on regular inspections or planned repairs. One of the main advantages of reactive maintenance is that it does not require complex administration or expensive planning, since intervention only happens when necessary.
In the long term, however, reactive maintenance carries numerous risks. Sudden breakdowns can significantly increase downtime, resulting in lost production and financial losses. Unexpected repairs can be costly, especially if the failure affects parts that cannot be sourced immediately. Sudden problems can also increase safety risks, as a broken piece of equipment may pose an accident hazard to workers and the environment. In addition, a faulty machine can even have a negative effect on product quality, leading to customer dissatisfaction.
Both preventive and reactive maintenance have their own advantages and disadvantages. The decision on which strategy is appropriate depends largely on the operating characteristics of the given business, the type of equipment and the financial consequences of possible downtime. Ideally, companies apply a combined maintenance model that strikes a balance between costs and optimising the lifespan of the equipment.
How to choose the right maintenance strategy?
To choose the right strategy, it is first worth assessing the critical role of the equipment in the company's operation. If the failure of a machine would cause a significant loss of production and increase in costs, preventive maintenance may be the better solution. If the equipment is less prone to failure, or its repair can be handled quickly and cost-effectively, reactive maintenance can also be a workable option. The available budget and the capacity of human resources are also important considerations, since preventive maintenance may initially require a larger investment. The optimal solution is often a combined strategy that applies preventive maintenance to critical systems and reactive maintenance to lower-risk equipment.
