ITSM
ITILIT service management: the practices and tooling, most often ServiceNow, Jira Service Management or a similar platform, through which incidents, problems, changes and known errors are recorded and audited. An RCA that lands as a structured problem record in the ITSM system is inside the process the organisation is already audited against; a PDF in an inbox is not.
