The three different types of escalations are functional, hierarchical, and automatic. Here is how each is defined: 1. Functional escalation: A functional escalation refers to forwarding a customer's issue or concern to a specialist or department with the specific expertise or soft skills required to address it. 2. Hierarchical escalation: Hierarchical escalation is about escalating an issue up the organizational ladder, typically due to the severity of the issue or when it requires managerial or higher-level intervention for resolution. 3. Automatic escalation: Automatic escalation involves predefined criteria or triggers that, when met, result in the automatic escalation of an issue without manual intervention. This is often set up using call center software or automation tools.
