The customer aims to automate repetitive tasks like case escalation.

Workflow Rules in Salesforce Contact Center are designed to automate actions based on specific criteria, such as automatically escalating cases when certain conditions are met. These rules can be set to trigger alerts, field updates, or other actions like sending emails, thereby streamlining the process of case management without manual intervention.

Workflow Rules automate tasks based on set criteria, ideal for repetitive tasks like case escalation.

Case Escalation Matrix and Entitlement Management can also be part of the escalation process but are more about defining the parameters and rights of escalation rather than automating them.

Omni-Channel Routing is used more for routing tasks to the right agent rather than automating task execution.
