Distinguish between the different types of industrial maintenance to manage your work with a master's hand
Do you know all the different types of maintenance, what specific needs they meet and which software solutions are best suited to boosting productivity?
As a prudent and proactive company, you need to deploy a maintenance strategy to ensure that your equipment is well looked after and operating at optimum levels, so as to ensure the continuity of your business. Your productivity is at stake, as is customer satisfaction!
Can you tell the difference between preventive maintenance, corrective maintenance and predictive maintenance? What are they used for? Here's a quick overview of the different types of maintenance and the software used to manage them.
1. Preventive maintenance
Preventive maintenance is : carried out at predetermined intervals or in accordance with prescribed criteria and intended to reduce the probability of failure or degradation of the operation of an asset or the degradation of a service rendered" (AFNOR).to reduce the probability of failure or deterioration in the operation of an asset or the degradation of a service rendered" (AFNOR).
In a proactive approach, it takes several criteria into account to anticipate malfunctions in an asset or a service:
- regulations affecting certain equipment and infrastructures in order to comply with standards (in the pharmaceutical or aeronautical industries, for example),
- feedback from users and machine reports,
- manufacturers' recommendations, to be taken into account in particular with a view to applying the warranty or quality assurance in the event of a breakdown.
In the latter case, we sometimes talk about pre-determined maintenance, which does not depend on the actual state of the machines, but on statistical programmes supplied by the manufacturers (based on the mean time to failure [MTTF], for example).
There are two sub-categories of preventive maintenance: systematic maintenance and conditional maintenance.
2. Systematic maintenance
This is carried out according to a schedule or a periodicity of use (every month, every 500 products manufactured, every 10,000 kilometres, etc.). Because it is carried out at fixed intervals, it is relatively easy to manage, facilitates organisation and considerably reduces the risk of serious damage or deterioration.
It is particularly useful when :
- restarting takes a long time
- the shutdown has been going on for some time
- the failure causes significant costs
- the problem threatens safety.
3. Conditional maintenance
This is based on the condition, i.e. the actual state of the equipment, via continuous or regular monitoring and a direct connection.
The deterioration of the asset is measured by means of self-diagnosis, sensor information, wear measurement, etc. It is very economical, as it does not require extensive stock management, purchases or unnecessary interventions.
4. Corrective maintenance
As opposed to preventive maintenance, which anticipates malfunctions, corrective maintenance is carried out after the failure or breakdown of an asset or production line.
It involves repairing, restoring or replacing a part or piece of equipment, or correcting a bug or faulty computer programming.
There are two sub-categories of corrective maintenance: palliative maintenance and curative maintenance.
5. Palliative maintenance
Palliative maintenance is used to temporarily repair a fault, rather like a band-aid, so that the equipment can continue to function relatively normally.
It is a great help in avoiding stopping the activity in progress. However, it is important not to let the temporary situation drag on for too long, and to ensure that safety is maintained until a more permanent solution is found.
6. Corrective maintenance
The aim of corrective maintenance is to permanently repair the sources of breakdowns (as opposed to palliative maintenance). The equipment will therefore be replaced, in whole or in part, depending on whether the breakdown is major or minor, total or partial.
Some people use the term "curative maintenance" as a synonym for "corrective maintenance", but it is only a sub-category of the latter.
7. Predictive maintenance
Some people consider it to be part of preventive and condition-based maintenance, since it tends to monitor machines and the crossing of thresholds (wear, etc.) to avoid breakdowns.
But it should be classified separately. According to standard NF EN 13 306 X 60-319, predictive maintenance (the term predictive is an anglicism) is carried out by following forecasts extrapolated from theanalysis and evaluation of significant parameters of the deterioration of the asset, in particular thanks to sensors installed on the machines and connected (IoT, Internet of Things).
Maintenance management solutions
These respond to the major challenges of maintenance operations, in particular :
- optimising work scheduling,
- equipment reliability and efficiency, for optimum productivity,
- fewer breakdowns,
- reducing maintenance costs,
- maintaining contractual or regulatory quality of service,
- staff safety,
- stock management and replacement parts purchasing,
- customer satisfaction,
- optimising working conditions.
Service and route management solutions
These are platforms for planning and organising the logistics of service providers, availability, locations, material and immaterial resources, and invoicing for services.
In SaaS mode, they enable effective coordination of human resources and good communication between customers and maintenance service providers.

Ermeo
Ermeo is a SaaS solution that facilitates and optimises maintenance operations. During rounds and interventions, operatives enter their observations directly into the application and record any non-conformities using intuitive, intelligent and comprehensive forms. Team leaders can then access the data on the Ermeo web platform in real time, and plan any corrective action required. As a result, you can improve the efficiency of your agents by up to 20%, and reduce re-interventions by 70%.
Key features include
- Digitalisation of maintenance procedures,
- database of all forms and equipment, with a system of attributes to facilitate monitoring and analysis,
- data history (equipment, intervention, etc.),
- technical and business documentation that can be consulted on the move via the application,
- forms can be previewed as they are being designed,
- offline mode for operation even without a network,
- automatic generation of customisable reports,
- interconnection with other business software (CMMS, EDM, etc.) via the API,
- connection to leading BI tools (PowerBI, Qlik Sense, etc.) to optimise data analysis.
Kizeo Forms
Kizeo Forms makes it easier to manage rounds, manage teams in the field and, above all, dematerialise and standardise all your monitoring forms, such as work orders, for corrective or preventive maintenance operations.
