You need to use all of your resources as effectively and efficiently as you can. This means that you should automate wherever you can, and use people only for tasks that can’t be automated. It also means that you need to think carefully about what you can automate and about the circumstances where only a person will do; and about simplifying those processes you do decide to automate to eliminate wasteful or inefficient steps.

You should always optimize the work BEFORE you automate it, as automating something that is inefficient or ineffective may just result in you doing the wrong thing faster!

A service request is a formal request from a user for something to be provided. Service requests are typically less complex and are either approved or denied based on the budget, need, or urgency.

An emergency change to apply a security patch (A) is not a service request because it is an urgent change that needs to be made to address a security vulnerability. The implementation of a workaround (B) is not a service request because it is a temporary solution to a problem. Managing an interruption to a service (D) is not a service request because it is an incident that needs to be resolved.

Providing a virtual server for a development team (C) is a service request because it is a request for a new service that can be fulfilled by the IT department.
