Information Technology — Service Management — Part 1: Service Management System Requirements
ISO/IEC 20000-1:2018 is the formal specification for an IT Service Management System (SMS). Closely aligned with ITIL practices, it establishes mandatory controls for service catalog management, Service Level Agreements (SLAs), capacity planning, customer relationship management, incident and service request resolution, problem root-cause remediation, and release and deployment management.
Scope & Applicability
Internal IT service delivery teams, managed service providers (MSPs), and cloud infrastructure operators delivering digital services to internal and external consumers.
Non-Coverage Boundaries
Does not define specific software architecture or database schemas; it standardizes the organizational service delivery lifecycle, SLA metrics, and operational governance.
Key Clauses & Control Requirements
Clause 8.2: Service Level Management (SLA)
Documenting, negotiating, monitoring, and reporting measurable Service Level Agreements (SLAs), Operational Level Agreements (OLAs), and underpinning contracts.
Clause 8.6: Incident, Request & Problem Management
Strict workflow separating rapid incident restoration from deep problem investigation to eliminate recurring underlying root causes.
Clause 8.5: Change, Configuration & Release Management
Formal change advisory board (CAB) governance, configuration management database (CMDB) baseline tracking, and release packaging controls.
