What is a service ownership map?
A service ownership map is a maintained record of which team owns each production service, what that service depends on, and how to reach the owner, kept current enough to be trusted during an incident. It answers the question that stalls most large-estate investigations: not which dashboard is red, but who owns the thing that is red. A CMDB is meant to hold this and usually does not, because it is updated by hand. A working ownership map is built from deployment metadata, cloud tags, on-call rotations and observed traffic, then reconciled against the CMDB. It is a durable asset for incident response and RCA attribution.
Onepane builds and maintains the service and ownership map as part of coverage, and snapshots it at the moment of each incident to support attribution.
