The goal of which process is: "To improve the quality of management decision making by ensuring that reliable and secure information and data is available throughout the lifecycle"?

Knowledge Management is formally defined in ITIL as the process responsible for gathering, analyzing, storing, and sharing knowledge and information across the organization. Its primary goal is to improve the quality of management decision making by ensuring that reliable and secure information is available throughout the entire service lifecycle. The key enabler of this process is the Service Knowledge Management System (SKMS).

Availability Management focuses on ensuring IT services meet agreed availability targets, not on providing organizational knowledge to support decision making.

Service Asset and Configuration Management manages configuration items and their relationships in the CMS, not the broader organizational knowledge needed for management decisions.

Change Management controls the lifecycle of all changes to minimize risk to IT services, not to curate knowledge or information for decision makers.
