Create CI or Asset first assuming you are implementing Discovery?

[Suggy]

Assuming you are implementing Discovery, do you first create the Assets first which inturn create the CI using OOB business rule ‘Create CI on Asset Insert’ and then let Discovery update the remaining CI attributes?

or 

Do you discover the CIs using Discovery and let Assets get automatically automatically?

As per this article ServiceNow recommends to create Assets first.

But I want to hear from those who have worked on CMDB/Discovery/Asset management as to how you have implemented.

Thank you

In OOB there's a Business rule "Create CI on insert" which creates CI upon Asset record creation and synchronization will be done b/w Asset and CI. Serial number and Model category are required to create CI as they form CI name therefore, Asset creation is first, and then CI

For more information, you can refer to the following docs & Playbook
