IT service management (ITSM) is a set of policies, processes and procedures for managing the implementation, improvement and support of customer-oriented IT services. Unlike other IT management practices that focus on hardware, network or systems, ITSM aims to consistently improve IT customer service in alignment with business goals.

ITSM encompasses multiple IT management frameworks that can apply to centralized and de-centralized systems. There are multiple frameworks that fall under the ITSM discipline, and some address unique industry-specific IT needs, including those in healthcare, government or technology. Businesses using ITSM consider IT as a service, with a focus on delivering valuable services to customers, rather than a department that manages technology.
