The Standard

What ISO/IEC 20000-1 Covers

IT Service Management

The planning, design, delivery and continual improvement of IT services to meet the needs of the organisation and its customers.

Internal & External Providers

Applicable to organisations of any type or size that provide IT services, whether an internal IT department, an external provider, or a combination of both.

Integrates With Other Standards

Can be combined with other management system standards, such as ISO 9001 and ISO 27001, into a single integrated management system.

Current 2018 Edition

The standard was significantly revised as ISO/IEC 20000-1:2018 to align with modern IT service management practice.

Why It Matters

What ISO/IEC 20000-1 Does For Your Organisation

Improves service quality: gives a structured basis for planning, delivering and improving IT services consistently.

Wins more business: many tenders and enterprise customers expect ITSM certification before engaging an IT supplier.

Reduces service risk: structured processes help identify and manage risks to service delivery before they affect customers.

Keeps you current: ongoing surveillance audits ensure the system – and your certificate – stays live and credible.
