When both Cases and Work Orders share the same Service Level Agreement (SLA) , Salesforce best practice is to create a single entitlement process and apply it to both objects . This ensures consistency, reduces maintenance, and simplifies SLA tracking.

The entitlement process can be configured once and then linked via Entitlement Templates or automation for both record types.

Option B (Flow) adds unnecessary complexity if both objects share identical milestones.

Option C (separate processes) would create redundant configurations for the same SLA terms.
