It is a technical specification that establishes the requirements for an effective IT (Information Technology) service management system. This standard focuses on IT service management, providing a comprehensive framework to ensure that organizations providing IT services meet the needs and expectations of their customers.

Here are some key points of the standard:

1. Scope of Application: The standard applies to all organizations, regardless of size and sector, that offer IT services internally or externally.

2. Management System Requirements: ISO/IEC 20000-1:2018 establishes the requirements for the planning, implementation, monitoring, and continuous improvement of an IT service management system. This includes requirements for leadership, strategic planning, resource management, process management, service management, performance management, and continuous improvement.

3. Processes and Procedures: The standard defines the processes and procedures that must be implemented and followed to provide effective IT services. These processes include customer request management, incident management, change management, configuration management, problem management, and service continuity management.

4. Continuous Improvement: ISO/IEC 20000-1:2018 emphasizes the importance of continuous improvement in IT service management. Organizations should regularly monitor their performance, identify areas for improvement, and take corrective actions to ensure that IT services always meet customer needs and market expectations.

5. Alignment with ITIL: The standard is closely aligned with the ITIL (Information Technology Infrastructure Library) framework, which is a collection of best practices for IT service management. This alignment allows organizations to use ITIL as a guide to implement the requirements of the ISO/IEC 20000-1:2018 standard.

In summary, the ISO/IEC 20000-1:2018 standard provides a comprehensive and detailed framework for IT service management, helping organizations deliver high-quality IT services, improve operational efficiency, and maintain customer satisfaction.
