IT Service Management (ITSM) is a comprehensive discipline focused on the design, delivery, support, improvement, and governance of IT services. It encompasses the entire lifecycle of a service, ensuring that IT contributes effectively to business objectives. ITSM frameworks, such as ITIL, provide best practices for managing IT operations through well-defined processes like incident management, change management, problem management, and service level management. The domain emphasizes value creation for the customer and continual improvement of IT services and operations.
This domain covers the overarching principles, frameworks, and processes for managing IT services throughout their lifecycle. It includes, but is not limited to, service strategy, service design, service transition, service operation, and continual service improvement. Key areas within ITSM include incident management, problem management, change management, configuration management, service level management, and IT asset management. It is broader than individual ITIL practices or specific service desk operations, focusing on the integrated management of IT services to deliver business value.
