The CMDB Data Manager is the ServiceNow capability responsible for generating actionable governance tasks and assigning them to CI class owners and data stewards. These tasks appear directly in the "My Work" tab within the CMDB Workspace, enabling proactive and role-based CMDB governance.
CMDB Data Manager focuses on data lifecycle management, including archival, retirement, and cleanup of CIs based on defined policies. When lifecycle rules or retention thresholds are met--or when human validation is required--the Data Manager creates tasks to prompt responsible owners to take action. This ensures that CMDB data remains accurate, compliant, and lean over time.
