Start with customer impact
Classify issues by impact and urgency rather than technical complexity alone. A simple account question affecting many users may require faster coordination than a difficult but isolated configuration request.
Define the handoff
Every escalation should identify the next owner, the information required and the expected communication point. This prevents a ticket from moving teams without moving responsibility.
Keep the customer informed
Technical work and customer communication are separate responsibilities. Assign both so the customer receives useful updates while specialists investigate.
