What It Is
ISO/IEC 20000-1:2018 is the international certification standard for service management systems (SMS). It specifies requirements to establish, implement, maintain, and improve an SMS covering the full service lifecycle, using a risk-based, PDCA (Plan-Do-Check-Act) approach aligned with Annex SL for integration with other ISO standards.
Key Components
- **Clauses 4-10Context, leadership, planning, support, operation, performance evaluation, improvement.
- Operational domains in **Clause 8Service portfolio, relationships, supply/demand, design/transition, resolution/fulfilment, assurance.
- Core processes: Incident/problem management, change/release, configuration/asset, availability/continuity, security.
- Certifiable via accredited bodies with Stage 1/2 audits, surveillance, recertification.
Why Organizations Use It
- Drives service reliability, customer trust, risk reduction (e.g., 50% certificate growth).
- Enables market differentiation, procurement wins, integration with ISO 9001/27001.
- Voluntary but supports regulatory compliance, operational efficiency, stakeholder assurance.
Implementation Overview
