Which of the following is NOT a method for initiating requests?

Telephonic support is not considered a standalone method for initiating requests in the context of IT Service Management. Instead, it's typically viewed as a channel for assistance where users reach out for help rather than initiating requests through a structured process.

In contrast, the other methods—virtual agent, walk-up experience, and self-service—are proactive and facilitate direct interaction with the service management system. The virtual agent provides an automated way for users to submit requests, the walk-up experience allows users to present their issues in person for assistance, and self-service empowers users to directly submit their requests through an interface or portal, promoting efficiency and control over the process. These methods align more closely with the principles of ITSM that aim to improve user experience and service delivery.
