ITIL stands for Information Technology Infrastructure Library, which is a framework that standardizes planning, delivery, and maintenance across the IT services lifecycle, aligning IT with customer and business needs. ITIL is a collection of books that define processes and best practices for efficient IT Service Management (ITSM) and elaborates on all the activities required for delivering end-to-end IT services in any organization. ServiceNow ITIL is the integrated and process-based framework to handle IT services, offering guidance to create and operate the service desk that effectively communicates between IT providers and the user community.

ServiceNow ITIL includes tasks, checklists, processes, and procedures that are not necessarily specific to an enterprise or technology but are yet applicable towards enterprise strategies by maintaining competency and delivering values. ITIL supplements ITSM and helps ensure success by adopting and adapting, not the blanket application of one fixed set of activities. Organizations are assisted in creating a stable IT environment and service operations that improve customer support, limit threats, and reduce costs.

In summary, ITIL is a framework that defines best practices for ITSM, and ServiceNow ITIL is the integrated and process-based framework to handle IT services that offers guidance to create and operate the service desk effectively.
