Field Service Management (FSM) encompasses all processes and technical solutions for the efficient planning, control, and documentation of field service assignments. These include installations, maintenance, repairs, inspections, and support services carried out on site at the customer's premises or at external facilities. Key tasks include precise scheduling and appointment planning, end-to-end order management, the administration of resources such as spare parts, and smooth communication between internal and field service teams. Mobile real-time documentation of services is another key element. Modern FSM software digitizes service processes, shortens response times, optimizes resource utilization, and thus contributes to high service quality and customer satisfaction while reducing operating costs.
