TS ISO/IEC 20000-1

TS ISO/IEC 20000-1 defines the core requirements for a service provider that wants to establish and operate an information technology service management system (SMS). Its focus is not only on keeping services technically available, but on managing them in a controlled way so they are planned, governed, reviewed and continually improved to meet service and business needs.

What a service management system covers

An SMS is the set of policies, processes, responsibilities and controls an organization uses to deliver services consistently. The standard addresses the management activities needed to plan, establish, implement, operate, monitor, review, maintain and improve that system. In general technical terms, this means service quality is managed deliberately rather than left to ad hoc practice, with defined ownership, records and feedback loops supporting repeatable performance.

Why design, transition and delivery are treated separately

In service management, design defines how a service should work and what outcomes it is intended to achieve; transition is the controlled move from change or preparation into operation; delivery is the actual provision of the service to users; and improvement uses measurement and review to make the system better over time. These distinctions are important because they help organizations control service changes without losing reliability, traceability or alignment with requirements.

• The standard specifies requirements for a service management system.
• It covers planning, establishing, implementing, operating, monitoring, reviewing, maintaining and improving the system.
• It also includes the design, transition, delivery and improvement of services.
• It provides a management framework for more consistent and controlled IT service provision.
