• +What is a Technical Service?
• +Do you need to fully adopt CSDM at once?

Scenario drills

1. Where do 'sold products' fit?

   “Sales operations wants every SKU we sell in the CMDB. Which CSDM domain?”

   Approach

   • Manage domain — Product Offering / Sold Product classes, tied to Service Offerings.
   • Sold Products link to customer accounts, entitlements, and revenue — they're consumption-facing, not infrastructure.
   • Never model them under cmdb_ci_hardware or a random custom class.

   soldProduct.name         = 'Payroll — Gold';
   soldProduct.service_offering = svcOffering.sys_id;

   Alternate approach

   Alternate: if you only need subscription tracking, use the CSM Subscription table and reference the Service Offering — lighter than full Sold Product modeling.

   Pitfall

   Stuffing SKUs into Business Application creates a 5,000-row 'app' list nobody trusts.
