IT Service Management (ITSM) refers to the set of policies, processes, and tools that organizations use to design, deliver, manage, and improve the way IT services are provided to users. ITSM focuses on aligning IT services with business needs, ensuring efficient support, and maintaining high service quality. Popular ITSM tools, such as ServiceNow, help organizations handle service requests, incidents, and changes in a structured and secure manner. By implementing ITSM, companies can streamline IT operations, enhance user satisfaction, and reduce risks associated with IT service delivery.
