The function of an IT service management (ITSM) system is to streamline the delivery of IT services and improve overall efficiency within organizations. ITSM frameworks enable effective management of incidents, changes, and service requests, ensuring that IT aligns with business objectives. These systems often incorporate automation to simplify processes, reduce response times, and enhance user satisfaction. By providing a structured approach to IT service delivery, ITSM helps organizations maintain service quality, optimize resource use, and ultimately drive better business outcomes. Furthermore, ITSM promotes continuous improvement by analyzing service performance and user feedback.
