what is the difference between change request and service request?

Hi Guys,

i just want to know the fundamental difference between CR and SR in service now.

[Mike Allen]

We always approached it as change is a change in infrastructure (OS changes, patches, firmware updates, maintenance, etc.) while service requests are changes in day-to-day things users need to do their jobs (passwords, group changes, permissions, etc.).

Thanks Mr.Allen for your response,

could you please explain more in detail with the definitions and examples.

I like Mike's answer and would like to build on it.

A service request can be deemed as a request by a person to have another person ( or group ) take action to fulfill the request.

A change request is a way for a person to declare that there will be a change to the infrastructure.

This implies that a service request may result in one or more change requests where the technical staff need to change the infrastructure to satisfy a service request.

Don't forget that CRs are tied to CIs and therefore, items like documents are included as they are considered Configuration Items as well.
