Maintenance should not be a mystery. Computerized Maintenance Management Systems (CMMs) are specialized software designed for the collection and storage of maintenance-related information, which helps to ensure day-to-day operations run smoothly and the life cycle of physical assets is prolonged. They serve as an all-in-one solution for tracking paper records and Excel sheets. A Computerized Maintenance Management System works by organizing a database of information about the organization’s equipment. For example, when a CNC machine requires maintenance, the software automatically creates a work order. This order will contain information about what serial number machine was serviced, what manuals and warranties were provided, who exactly serviced the equipment (based on who was available at the time of inspection), who was assigned the work order, and what specific tasks had to be completed. Furthermore, through a mobile application, a technician can log all parts replaced during the repair. Eventually, the data will become available to the maintenance management team, which will analyze it to obtain such metrics as “mean time between failures” and total maintenance costs. The primary reason why a Computerized Maintenance Management System is a great idea for manufacturers is that having equipment breakdowns at the wrong time can be extremely costly. These programs help to shift from a reactive to a proactive approach by keeping track of all procedures and ensuring that no work is done late. In addition, they eliminate the problem of lost or misplaced work orders since digital paperwork is much easier to manage than stacks of papers on a manager’s desk. Most often, these systems feature job planning, which allows for assigning the work to a specific team and reminds them of approaching deadlines. Moreover, Computerized Maintenance Management System software typically offers a very detailed equivalent of a “medical history” for a piece of machinery, which means that it is much easier to decide whether it makes financial sense to repair or replace the equipment. In terms of inventory management, having a program that tracks all expenses and warns about the critical levels of spares is much better than a chance-based approach. Many programs offer specialized audit trail features that are particularly useful for healthcare and food and beverage industries due to their specific regulatory requirements. It is also worth mentioning such features as work order management, preventive maintenance, hierarchical asset management, mobile and field service management, predictive maintenance (which often includes IoT integration), and MRO inventory management. For manufacturers, the most beneficial types of such programs fall under the categories of equipment-intensive industries. These include the manufacturing sector itself, healthcare, facilities management, and energy and utilities. The last two often require specialized software for remote asset monitoring. When selecting the software, it is crucial to keep in mind that a CMMS should be based on a prioritized set of organizational needs. It should be highly intuitive and user-friendly to prevent additional headaches for the maintenance teams. It must also include a robust preventive maintenance module and be compatible with other integrated systems, especially the enterprise resource planning module. MRO inventory tools would be a definite bonus. Finally, if possible, a trial version should be available to test the software with one’s own data. Computerized Maintenance Management Systems are no longer a luxury but a necessity for any organization that possesses physical assets. They keep costs low, increase productivity, and reduce the likelihood of major breakdowns.
