ISO/IEC 20000 — IT Service Management Standard
ISO/IEC 20000-1:2018 certification consulting — SMS design, audit preparation, and service management process implementation for IT service organisations.
Understanding ISO/IEC 20000 — IT Service Management Standard
What Is ISO/IEC 20000
ISO/IEC 20000 is the international standard for IT Service Management. It specifies requirements for a Service Management System (SMS) — the set of policies, processes, and documented information that enables an organisation to plan, design, deliver, and continually improve managed IT services.
Relationship to ITIL
ISO/IEC 20000 provides the certifiable standard while ITIL® provides the supporting best-practice guidance. The two are complementary: organisations that have adopted ITIL processes are well-positioned to meet the requirements of ISO/IEC 20000-1 and to achieve independent certification.
Why Certification Matters
Certification provides independent assurance of service quality to customers, enables eligibility for public-sector and enterprise procurement frameworks, and establishes a structured foundation for continual service improvement across the organisation.
Where Most Organisations Get Stuck
Undefined SMS Scope
Insufficient Process Documentation
Siloed Service Teams
Internal Audit Readiness Gaps
Sustaining Continual Improvement
Key Requirements
ISO/IEC 20000-1:2018 organises requirements across nine clauses, covering leadership, planning, support, operation, and performance evaluation of the SMS lifecycle.
Service Management System
Define the SMS scope, policy, and objectives. Establish governance including top management commitment and assigned responsibilities.
Service Design & Transition
Plan and control new or changed services through formal design, build, and transition processes to prevent unintended service disruption.
Delivery of Services
Operate service management processes including incident, problem, change, capacity, availability, and service continuity management.
Relationship & Agreement Processes
Manage supplier and customer relationships through defined service level agreements and supplier contracts.
Performance Evaluation
Monitor, measure, audit, and review SMS performance against policy and objectives through internal audits and management reviews.
Scope of Engagement
SMS Gap Assessment
Evaluate current service management practices against each clause of ISO/IEC 20000-1:2018 to identify conformity gaps.
Scope & Policy Definition
Define the SMS scope boundaries, service management policy, and measurable objectives aligned to the service catalogue.
Process Design
Design or refine service management processes to satisfy standard requirements, including RACI matrices and process artefacts.
Internal Audit Programme
Conduct pre-certification internal audits and management reviews with formal corrective action tracking.
Certification Preparation
Prepare documentation, evidence packs, and artefacts for the stage 1 and stage 2 external certification audits.
Continual Improvement Programme
Establish CSI processes and measurement frameworks to sustain certification and drive ongoing service quality improvement.
