TS ISO/IEC 20000-1

TS ISO/IEC 20000-1 is an information technology standard focused on the requirements a service provider must meet to operate a service management system for managed services. In technical terms, it defines a conformity framework for service management capability, rather than prescribing how a specific service must be designed.

What it means in service management practice

IT service management is concerned with keeping delivered services reliable, controlled, supportable, and aligned with user needs. In everyday practice, this typically involves service levels, incident handling, change control, continuity, and capacity considerations. The subject of this standard is the organisational discipline needed to manage those activities within a formal system.

As general technical context, standards of this kind help an organisation manage services through defined roles, measurable objectives, documented processes, and traceable control points. That gives service providers a common structure for planning operations, addressing risk, managing customer expectations, and improving service performance over time.

• Controlled and traceable management of service delivery
• Definition of internal processes and responsibilities

This TSE record is based on ISO/IEC 20000-1:2005 and is marked withdrawn. The description therefore reflects the standard’s technical focus on service management requirements, not a claim of current validity or certification status.
