Which of the following is a widely recognized ITSM best practice framework?

ITIL, which stands for Information Technology Infrastructure Library, is a widely recognized best practice framework in IT Service Management (ITSM). It provides a comprehensive set of guidelines and practices focused on aligning IT services with the needs of the business. ITIL aims to improve efficiency and achieve predictable service levels by providing a structured approach to service management, including incident management, change management, service level management, and more.

The framework is built around core principles that support best practices in service delivery and ongoing improvement. By using ITIL, organizations can standardize their service management processes, leading to enhanced service quality, reduced operational costs, and increased customer satisfaction. Its widespread adoption across various industries, particularly in IT service management, highlights its importance and validity as a leading framework in the field.

In contrast, while Agile, Scrum, and Lean Manufacturing are important methodologies and concepts in their respective areas, they do not specifically focus on IT Service Management like ITIL does. Agile and Scrum are primarily associated with software development, and Lean Manufacturing is focused on optimizing production processes rather than IT service delivery.
