CMMS System in Maintenance as a Way to Optimize Production

Maintenance is still often associated with a department that has to be reactive. Something breaks, a machine stops – we call maintenance. It is time to challenge this perception, thanks to a tool that organizes the daily work of maintenance and turns chaos into a predictable process.

We are talking about CMMS-class systems (Computerised Maintenance Management System). I can say with full confidence that they form the foundation of modern work organization in technical departments. Why? Because they enable a shift from a breakdown-response model to a planned prevention system. Implementing such a solution in a manufacturing plant helps structure processes that have often relied on informal communication or paper records. This article outlines the role of a CMMS system, its integration with other IT solutions, and the real business benefits resulting from its use.

The CMMS system from explitia is a tool dedicated to maintenance management in a manufacturing plant, which can operate as a standalone system or as a module of the Production Portal. This makes the solution highly flexible and tailored to individual customer needs. The primary objective of implementing this tool is to ensure maximum availability of the machine park by collecting information about the technical condition of equipment from various sources.

CMMS implementation reduces unplanned downtime and precisely organizes the work of the maintenance team. Although the main target group of the system is technical staff, its reporting section provides valuable information to management and supervisors who monitor machine performance. As a result, the system becomes a working tool not only for the maintenance department and mechanics, but also for the managerial level.

In many manufacturing plants, maintenance work is still disorganized – failure reports are communicated verbally, by phone, or on paper notes. This form of communication generates numerous issues, especially in facilities where operators cannot use personal phones or where there are signal problems on the shop floor. The lack of archiving such reports prevents later data analysis and drawing conclusions.

A CMMS system takes control of these processes by introducing full event registration. Each report, commonly referred to as a ticket, includes:

A maintenance technician can attach photos, videos, or PDF instructions to the ticket, which significantly speeds up the repair process. As a result, the working day of the technical department is better planned and its efficiency increases. Digital tools become for maintenance what spreadsheets and project management software are for supervisors.

An important aspect of the IT architecture in a modern factory is understanding the difference between MES and CMMS. An MES system answers the question: “how do we produce?”, while CMMS focuses on: “why are we not producing?” and “what needs to be done to return to production as quickly as possible?”. CMMS solves problems that MES does not handle, such as scheduling recurring machine inspections and procedures for checking specific components.

Integrating these two systems creates a synergy in which MES becomes an automatic source of reports for CMMS. When a machine stops, information about the event can immediately be transferred to CMMS as a new ticket. This synchronizes data between systems and provides the full spectrum of information about the production process. A shared data environment makes it possible to combine information from MES, CMMS, and even ERP or EMS modules.

One of the most advanced uses of a CMMS system is linking it with the production planning module. In plants where machines are frequently changed over for different recipes and products, the MES system can generate maintenance requests related to preparing equipment for a specific time. This way, the technical department knows exactly when and what the machine must be changed over for – without tracking detailed sales plans that are not relevant to them.

CMMS also facilitates communication between planners and maintenance, eliminating conflicts of interest. Planners can see time slots reserved for technical inspections in the system and do not schedule production during that time, which prevents operational chaos. On the other hand, maintenance can flexibly reschedule planned work in the calendar in response to urgent high-priority failures. Transparency of resource availability ensures that each side knows what the technical team is currently working on.

The overarching purpose of a CMMS system is to implement a predictive maintenance strategy and regular prevention. The system enforces cyclical tasks according to the schedule, helping prevent faults, keep machines in optimal technical condition, and reduce service costs. Based on historical data on the number and types of tickets, the system enables forecasting potential future issues.

As part of prevention, CMMS also supports spare parts management. Although this is an additional function, it allows for:

Integration with an ERP system also enables tracking costs related to invoices and spare parts orders.

The effectiveness of CMMS implementation is measured using KPIs, the most important being MTTR and MTBF.

Both indicators directly influence machine availability, which is a component of OEE (Overall Equipment Effectiveness). A CMMS system provides the necessary data to determine whether a stoppage was planned or resulted from a sudden breakdown – which is essential for reliable performance assessment of the plant.

The lack of a CMMS system generates hidden costs in three main areas:

Without an appropriate management tool, companies often unnecessarily expand technical teams, trying to compensate for low efficiency with additional headcount. A CMMS system enables optimal use of existing human resources without generating unnecessary labor costs.

Proper inspection management extends the lifespan of spare parts, which fail less often when properly serviced. The biggest losses, however, come from unplanned downtime – every hour a machine stands still instead of producing reduces company profits and decreases the amount of product available for sale.

The greatest benefits of implementing a CMMS system are achieved by larger-scale plants with extensive maintenance departments and automated production lines. In such organizations, the system is essential to maintain business continuity and control over processes. According to experts’ experience, customers often decide to implement CMMS even before MES, as it solves urgent organizational problems at a relatively lower cost.

This system is usually not recommended for very small, one-person maintenance departments and companies relying exclusively on manual or semi-automated production. In such cases, due to low failure rates of simple tools and a lack of extensive automation, return on investment in advanced software might be unattainable.

A CMMS system is a modern tool that permanently changes the way a maintenance department operates by bringing order to the daily work of technicians. Thanks to integration with MES and planning modules, CMMS becomes the central point of information about machine park availability and repair process effectiveness. Implementing this solution not only enables faster failure removal (MTTR), but above all allows effective prediction and prevention of failures in the future. For companies striving for full production optimization, CMMS is a natural step toward digitalization that delivers measurable economic benefits through better resource management and minimizing losses caused by downtime.
