The Global Standard for IT Service Management: An Overview of ISO/IEC 20000

In today's fast-paced, digitally driven world, organizations face immense pressure to deliver high-quality IT services that are reliable, efficient, and cost-effective. Ensuring that IT services are aligned with business needs while maintaining control, accountability, and continual improvement can be challenging. This is where ISO/IEC 20000 comes into play.

ISO/IEC 20000 is the international standard for IT Service Management (ITSM). It provides a structured framework to help organizations effectively manage and improve their IT services. Whether you’re a multinational enterprise or a growing startup, implementing ISO 20000 can be a strategic asset to elevate your service delivery and customer satisfaction.

What is ISO/IEC 20000?

Originally published in 2005 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), ISO/IEC 20000 is the first international standard specifically for IT service management.

It sets out the requirements for establishing, implementing, maintaining, and continually improving a service management system (SMS). The goal is to ensure that the organization consistently delivers services that meet customer requirements and provide value.

ISO/IEC 20000 is based on the ITIL (Information Technology Infrastructure Library) framework but is independent of any specific methodology, making it flexible and adaptable to various industries and service models.

Key Benefits of ISO/IEC 20000
