Maintenance Key Performance Indicators, or maintenance KPIs, are increasingly used tools in companies. They are particularly useful for optimizing the management of machine and equipment maintenance.
To make the most of this lever for improvement, it is necessary to follow your maintenance KPIs thanks to an adapted and high-performance CMMS. In this sense, mobile CMMS is a particularly relevant tool.
The term KPI refers to key performance indicators used for decision support in organizations. They are particularly used in organizational performance management, and are generally used to meet the following objectives:
- continuous improvement.
When it comes to maintenance, KPIs make it possible to monitor, compare and improve interventions on machines and equipment.
Choosing the right indicators to obtain good maintenance KPIs
To benefit from useful maintenance KPIs through your CMMS, it is important to carefully choose relevant features and indicators.
The availability rate indicates the extent to which a piece of equipment is capable of performing a required function, according to specific time conditions.
This rate therefore depends on:
- the number of breakdowns, i.e. reliability;
- speed of repair, i.e. maintainability;
- defined procedures, i.e. the organization of maintenance;
- the quality of the means available, i.e. logistics.
There are three different types of availability.
Gross availability rate
This rate is used to compare the operating time with the availability of the equipment to determine whether or not it is in a situation of overcapacity. This indicator gives the machine utilization rate and helps to avoid unnecessary purchases of equipment.
Net availability rate
Net availability is the gross availability minus the "causes of non-functioning" of a piece of equipment. These can be:
- production stoppages (repeated at weekends or one-off stoppages over longer periods) due to a lack of demand;
- national strikes that have to be managed internally;
- interruption of energy sources for reasons external to the production site.
Intrinsic or inherent availability rate
This rate indicates the probability that a piece of equipment will function properly, taking into account only the time the equipment is in operation and actively repaired. It is calculated as follows: MTBF + MTTR. The MTBF is the mean time between failures, and the MTTR is the mean time to repair.
The main reliability indicator is the MTBF (Mean Time Between Failures). It indicates the probability that a machine will perform a required operation within a given time period and under given conditions.
There are other reliability indicators such as the MTTF (Mean Time Before Failure), which indicates the average operating time of a piece of equipment before its first failure, or the MUT (Mean Up Time).
The relevance of maintenance
The relevance of maintenance can be measured by analyzing certain indicators, such as:
- the scheduling rate, which is the sum of the hours planned for the scheduled operations divided by the total number of hours available, which ideally is 100%;
- the plan completion rate, which measures all factors that could disrupt the planned operation on a daily basis, and which is the sum of planned duration of planned and completed operations divided by the sum of planned hours of planned operations.
Effectiveness of interventions
The maintainability of a piece of equipment is measurable through the effectiveness of the interventions. This can be measured by the probability that a stopped machine is back in service after a given time.
CHOOSING THE RIGHT CMMS TO FOLLOW MAINTENANCE KPIS
The effectiveness of maintenance KPIs tracking and analysis depends greatly on the CMMS used.
The role of CMMS in performance measurement
CMMS is a fundamental tool for measuring maintenance performance through key indicators. It provides both :
- performance measurement indicators ;
- a toolbox for improving performance;
- benchmarking tools.
The performance indicators, some of which are listed above, provide precise quantitative data. Thanks to CMMS, it is possible to measure, analyze and report these data, for example in a dashboard. The more powerful and ergonomic the software is, the faster and more useful the analysis of maintenance KPIs will be, and the simpler and more accessible their restitution will be to all maintenance teams.
Mobility Work is provided with an analytic tool to help you analyze all your maintenance data and adapt your strategy
At the same time as the collection of maintenance KPIs, a mobile and high-performance CMMS like Mobility Work allows to act positively on each of the indicators and to gain in productivity and reactivity at each moment of the processing of a curative intervention. It will thus provide, in real time, answers to questions such as "Who is the most competent and available technician to quickly solve this problem?”, "What is the most likely cause of this breakdown?" or even "What spare parts are needed for this intervention? ».
Finally, a next-gen CMMS makes it possible to benchmark between different periods of activity, different teams, etc. It thus enables a detailed analysis that guarantees the success of maintenance operations and improves the company's overall productivity.
Reconciling two visions of maintenance thanks to mobile CMMS
For optimal maintenance management, it is important to take into account two visions:
- the field teams’ one and the search for improvements in operational performance and working conditions ;
- the management's one, including the motivation of teams and the achievement of financial objectives.
Thanks to mobile CMMS, you can reconcile these two visions: on the one hand, field teams have a high-performance tool that greatly facilitates their task and therefore encourages them to seek continuous improvement. On the other hand, managers and supervisors have a powerful means of analyzing and rationalizing their maintenance strategy.
The definition and monitoring of KPIs are both delicate and strategic areas of maintenance management. With mobile CMMS, these key steps are much easier to perform. A solution such as Mobility Work also makes it possible both to optimize maintenance management thanks to relevant maintenance KPIs and to involve all the employees concerned.
