Knowledge-Centered Support (KCS) is a knowledge management methodology that focuses on knowledge as a key asset of an organization. It involves capturing knowledge as a byproduct of resolving issues, structuring the knowledge for readability and consistency, and reusing the knowledge to resolve similar issues faster. Practices of KCS include knowledge engineering, leadership and communication, performance assessment, and integrating KCS with other IT service management processes. KCS provides benefits like faster issue resolution, reduced redundancy, improved customer experience, and increased organizational learning.
