Final answer:
According to ITIL, customer satisfaction is NOT an input to a service desk single point of contact.
Step-by-step explanation:
In the context of ITIL (Information Technology Infrastructure Library), the service desk is a single point of contact for users to report IT-related issues and request assistance. The inputs to a service desk include various sources of information that help facilitate effective incident management and problem resolution.
Among the inputs to a service desk, **not** considered part of a single point of contact is **customer satisfaction**, which is an output represented by feedback or surveys collected from customers after their interaction with the service desk.
Other common inputs to a service desk include **tickets** (or incident records), **knowledge base articles**, **service level agreements (SLAs)**, **escalation procedures**, and **performance metrics**.
