IT Service Management (ITSM) encompasses the practices, policies, and processes that organizations use to design, deliver, manage, and improve IT services. ITSM focuses on aligning IT services with business needs to deliver value efficiently and effectively.

The core of ITSM is the service lifecycle, often structured around ITIL (Information Technology Infrastructure Library) best practices. The lifecycle consists of five key stages:

1. Service Strategy: Defining service goals and aligning them with business objectives.
2. Service Design: Planning and designing new or improved IT services.
3. Service Transition: Implementing changes or new services while minimizing disruption.
4. Service Operation: Managing day-to-day service delivery and support.

Continual Service Improvement (CSI): Using data and feedback to refine services.
ITSM frameworks often utilize service desk tools like ServiceNow, BMC Helix, or Zendesk, which facilitate ticketing, change management, and incident resolution.

Key benefits of ITSM include improved service quality, increased efficiency, and better alignment between IT and business objectives. By adopting ITSM practices, organizations can reduce downtime, enhance user satisfaction, and ensure compliance with industry standards.
