Knowledge Management platforms give IT and adjacent engineering teams a governed home for runbooks, system documentation, standard operating procedures, troubleshooting guides, onboarding materials, and internal reference content. Core capabilities include structured authoring, hierarchical organization and spaces, version history, granular access control, full-text and semantic search, content ownership and review workflows, and integration with ticketing and chat systems so documentation surfaces in the moment of need. The category spans general-purpose wikis and IT-specific knowledge bases embedded in ITSM suites.
