What CSDM Data Does SNWR’s Go-Live Need?
On this page
In this lesson, you will learn:
- Why you don’t load the whole CMDB first
- What SNWR’s ITSM uses on day one
- What can wait
- Service portfolio versus enterprise portfolio
🔁 Quick look back: Last time: Using Services in Incident and Change. You learned how SNWR makes Service and Service offering required on incidents, filled from the CI.
1 “We can’t go live until the CMDB is perfect”
Hana wants every server, laptop and app in the CMDB before go-live.
- That’s 4,000 CIs.
- It would take six months.
- Go-live is in eight weeks.
👉 The fix: load only what ITSM will use on day one, and grow it after.
2 What ITSM uses on day one
Key term: CSDM
The Common Service Data Model: ServiceNow’s guide for how services and CIs fit together.
Key term: Application service
A running app that supports a service, like the SNWR Email system on its servers.
3 Two different branches
| CSDM branch | What it’s for |
|---|---|
| Service portfolio (Sell / Consume) | Services and offerings people use. ITSM needs this. |
| Enterprise portfolio (Design) | Business apps and their owners. Useful later, not needed for go-live. |
⭐ Remember: There is no single “minimum CMDB”. Ask: what will our records point to on day one?

4 Quick recap
- Don’t wait for a perfect CMDB
- Load what incidents, changes and requests will point to
- SNWR day one: two services, two offerings, three CIs
- Laptops and full discovery can wait
- Service portfolio and enterprise portfolio are different branches
