The Industrial Production and Maintenance sector plays a key role in the economy and society in general. As it involves the production and maintenance of industrial products (machinery, electronics, equipment), it creates a wide range of jobs, thus developing the economy and enhancing the competitiveness of businesses. Beyond the economic importance of industrial production, it is equally essential to maintain industrial facilities according to international quality standards to maintain safety and avoid accidents. The sector makes a complementary contribution to innovation and technological improvement. The fact that industrial production and maintenance are closely linked to environmental protection and sustainability, with the required objective of reducing pollutants and creating a positive environmental footprint, is another key factor in optimising processes. Staff certification demonstrates that employees are trained with the necessary expertise in production and maintenance. Thus, a certified workforce guarantees the high quality of products and services in the industrial sector, inspiring customers and partners with the confidence that all work is carried out to regulatory standards and with the highest possible quality and safety. In general, the certification of personnel in the production-maintenance sector is essential, since it is an irrefutable indicator of the smooth operation of enterprises. In a more person-centred conceptual framework, a certified worker can enhance his or her knowledge and skills so that he or she becomes an indispensable and irreplaceable part of the workforce, contributing to the operational efficiency of operations. Modern specialties that require trained and certified personnel in the industrial sector are: Plant Maintenance Technician, Automation and Automatic Control Plant Maintenance Technician, Refrigeration Plant Technician, Industrial Production Manager
