ITService

ITservice is a term used to describe the delivery of information technology services to meet the needs of organizations and users. It encompasses the planning, design, provision, operation and continual improvement of information technology resources and services. IT services may be delivered by in-house IT departments or by external providers, commonly known as managed service providers, cloud providers, or IT outsourcing firms.

IT service management (ITSM) is the discipline that coordinates people, processes and technology to ensure IT services deliver value. ITSM is often guided by frameworks such as ITIL and standards such as ISO/IEC 20000, which describe best practices for service design, transition, operation and continual improvement. Core processes include incident management, problem management, change management, configuration management, service level management, release management and service request fulfillment, supported by a service desk and a configuration management database (CMDB).

Delivering IT services can follow various models, including on-premises, hosted, or cloud-based options such as IaaS, PaaS and SaaS. A service catalog defines available services and service level agreements (SLAs) establish performance expectations. The service lifecycle is used to plan, deliver and continuously improve services from strategy through design, transition, operation and improvement.

Common IT services include help desk support, software installation and maintenance, asset and configuration management, network and systems monitoring, data backup and disaster recovery, cybersecurity services, cloud management and IT consulting. Metrics such as uptime, incident response time and SLA compliance are used to evaluate performance. Security, governance and compliance considerations are integrated into IT service delivery.
