Introduction
Information technology has become the backbone of modern organizations. Businesses across industries rely on IT systems, applications, cloud platforms, networks, cybersecurity solutions, and digital services to support daily operations, customer interactions, and strategic decision-making. As dependence on technology increases, organizations face growing expectations to deliver reliable, secure, efficient, and continuously improving IT services.
Poor IT service management can result in system failures, service disruptions, dissatisfied customers, reduced productivity, financial losses, and damage to organizational reputation. Therefore, organizations require structured processes to manage IT services effectively, align technology with business objectives, and ensure consistent service delivery.
To support organizations in managing IT services systematically, the International Organization for Standardization (ISO) and the International Electro Technical Commission (IEC) developed ISO/IEC 20000-1:2018 - Information Technology - Service Management - Part 1: Service Management System Requirements.
ISO/IEC 20000-1:2018 provides a globally recognized framework for establishing, implementing, maintaining, and continually improving an IT Service Management System (ITSMS). It enables organizations to manage service delivery, improve customer satisfaction, optimize IT processes, control risks, and enhance operational performance.
