Preventive maintenance[5]​ can be carried out according to different criteria:

• - Scheduled maintenance, reviews are carried out by time, mileage, hours of operation, etc. So if we take a car for example, and we determine a scheduled maintenance, the tire pressure is checked every three months, the engine oil is changed every 10,000 km, and the timing belt is changed every 90,000 km.

• - Predictive maintenance tries to determine the moment at which repairs should be carried out through monitoring that determines the maximum period of use before being repaired.

• - Opportunity maintenance is that which is carried out taking advantage of periods of non-use, thus avoiding stopping the equipment or facilities when they are in use. Returning to the example of the car, if we use the car only a few days a week and we intend to take a long trip with it, it is logical to carry out inspections and possible repairs on the days when we do not need the car, before starting the trip, thus guaranteeing its proper functioning during it.[6]​.

Relative to computing, maintenance is the review of equipment in operation to ensure its good performance, both hardware and software on a computer or PC. These influence reliable system performance, the integrity of stored data, and correct information exchange at the highest possible speed within the optimal system configuration.

Within preventive maintenance there is software that allows the user to constantly monitor the status of their equipment, as well as make small adjustments in an easy way.

We must also add that preventive maintenance in general deals with determining the operating conditions, durability and reliability of the equipment in question. This type of maintenance helps reduce downtime that can be generated by corrective maintenance.

Regarding preventive maintenance of a software product, it differs from other types of maintenance, especially update maintenance, which generally occurs after a request for change by the client or end user or after a study of possibilities for improvement in the different modules of the system, preventive maintenance is produced to guarantee operation under the current conditions of performance, safety and reliability.

Although preventive maintenance is considered valuable for organizations, there are a series of failures in machinery or human errors: breakdowns, misuse, etc. which are unpredictable when carrying out these maintenance processes.

Scheduled preventive maintenance and planned equipment replacement are two of the three policies available to maintenance engineers.

• - Computer-aided maintenance management.

• - Maintenance.

• - Corrective maintenance.

• - Productive maintenance.

• - Total productive maintenance.

• - Software maintenance.

• - Preventive maintenance procedure.

Preventive Maintenance[1]​ is a strategic approach that involves the regular performance of planned tasks of inspection, cleaning, adjustment and replacement of components with the objective of preventing failures and maintaining optimal performance of equipment and systems. Although it may require an initial investment of time and resources, the long-term benefits of this approach are significant and span a variety of key areas:.

• - Operational Cost Reduction: Preventive Maintenance allows you to identify and address potential problems before they become critical failures. This reduces the need for costly emergency repairs and minimizes unplanned downtime. In the long term, this strategy can lead to decreased maintenance costs and greater efficiency in overall operation.

• - Extension of Useful Life: The constant performance of inspections, cleanings and adjustments guarantees that the equipment works in optimal conditions. This reduces component wear and fatigue, which in turn extends equipment life. By preventing premature deterioration, organizations can maximize their investment in assets and delay the need to replace them.

• - Greater Availability and Reliability: Preventive Maintenance addresses problems before they become obstacles to operation. This increases the availability of equipment and systems, since the probability of unexpected failures is reduced. Assets become more reliable, contributing to customer satisfaction and business process continuity.

• - Efficient Resource Planning: By scheduling maintenance tasks in advance, organizations can plan resource allocation more effectively. This includes staff scheduling, spare parts procurement, and downtime optimization. Careful planning minimizes impacts on production and facilitates supply chain management.

• - Safety Improvement: Preventive Maintenance not only focuses on operational efficiency, but also on safety. By ensuring that equipment meets safety standards and functions properly, the risks of workplace accidents and dangerous situations are reduced.

• - Regulatory Compliance: In many industries, there are regulations and standards that require regular maintenance of equipment. Preventive Maintenance guarantees that organizations comply with these legal requirements, avoiding fines and sanctions.

• - Lower Environmental Impact: By keeping the equipment in optimal conditions, the generation of waste and the need to frequently replace components are reduced. This contributes to more sustainable practices and reduced environmental impact.

• - Increased Operational Efficiency: Preventive Maintenance ensures that equipment operates at its maximum efficiency, which can lead to more efficient use of energy and resources. This has a positive impact on the overall productivity of the organization. “Preventive maintenance allows you to reduce the MTTR (Mean Time to Repair) by anticipating minor failures.” [4]​.
