Simple definition
Functional escalation transfers a case to a specialist team with the technical skills required to investigate or resolve it.
Purpose and use
Functional escalation engages a person or team with the technical expertise required for a case.
How does it work?
It can involve specialist support, an application team or a supplier without necessarily being a management decision.
Example and verification
For a network incident involving an application, state completed checks and the technical question the next team must address.
Points to watch
Specialization does not remove the need for coordination when several teams participate. Handoff without a clear question can merely move the ticket.
In short
The appropriate recipient has the technical capabilities needed for the remaining investigative step.
