Which IT framework would you use to improve IT service management?

The correct choice to improve IT service management is ITIL (Information Technology Infrastructure Library). ITIL provides a comprehensive framework for managing IT services effectively, focusing on aligning IT services with the needs of the business. This framework emphasizes best practices for service management, guiding organizations on how to deliver high-quality IT services consistently.

ITIL encompasses various stages and processes, including service strategy, service design, service transition, service operation, and continual service improvement. By adopting ITIL, organizations can enhance their service delivery, increase efficiency, and ensure that IT services are aligned with business objectives, ultimately leading to higher customer satisfaction.

In contrast, while COBIT is a comprehensive framework for governance and management of enterprise IT, it is broader and more focused on ensuring that IT investments align with business goals rather than specifically improving service management processes. ISO/IEC 27001 is predominantly focused on information security management and does not directly target IT service management practices. PRINCE2 is a project management methodology that outlines how to manage projects effectively but does not specifically address the operational aspects of IT service management.
