Common Service Data Model (CSDM)
CSDM is the model that makes everything else on ServiceNow coherent. Get it right and the platform works; ignore it and every workflow ends up arguing with another about what a “service” actually is.
Why it matters
CSDM is not a module — it is the agreement about how Application Services, Business Services, Technical Services, Service Offerings, Products, and supporting CIs relate. Without that agreement, every team builds their own definition, and the platform quietly fragments.
The pattern we see most often: organizations adopt CSDM on paper, then revert to legacy CI naming and homegrown service models in practice. Six months later, dashboards disagree, change risk is uncomputable, and CSDM becomes a topic everyone has opinions about and no one owns.
A successful CSDM adoption is part data architecture, part governance, and part organizational change. We treat it as all three. The deliverable is not a slide deck; it is a working model that ITSM, ITOM, SPM, and SecOps all rely on without renegotiation.
When CSDM is real, executive reporting, change risk, and service-level conversations stop requiring a translator.
How Amazon Consulting helps
CSDM engagements fail when they become academic. Ours stay close to the workflows that depend on the model — and we measure adoption, not theory.
Current-state model
Document existing service definitions, CI classes, ownership, and the gaps between what the data model says and what teams actually do.
Target CSDM design
Define Business Services, Service Offerings, Application Services, and Technical Services for your context — pragmatic, not exhaustive — and align CMDB classes accordingly.
Migrate & govern
Migrate legacy service records, retire duplicates, define ownership, and stand up the governance forum that keeps the model honest over time.
Prove it in workflow
Hook CSDM into change, incident, and service-level reporting so the model earns its keep. Adoption is what makes CSDM real.
Recent engagements
Recent CSDM engagements have tended to be remediation work — organizations that adopted CSDM nominally, then realized their dashboards and reporting still relied on legacy structures. The pattern is consistent and the fix is methodical. Specifics under NDA.

A short assessment usually surfaces where the model has drifted from the workflows. We can map the gap and a realistic path back.
