what is difference between change type and chage model in service now? Explain

Change Type defines the category and risk level of a change, such as Standard, Normal, or Emergency. It controls high-level behavior like approvals and governance.

Change Model is a reusable template that standardizes how a change is executed, including predefined tasks, approvals, timelines, and conditions.

Hi @ayushup , 
change type classifies what kind of type it is like - Normal, Standard or Emergency , which defines risk level and approval.

change model which shows how to implement the change type by using the predefined workflows, states and tasks which helps to streamline the process.

hi @ayushup ,

This is a very valid question and one that comes up frequently during workshops and real implementations.

Change Type

As per ITIL, Change Type defines the nature and urgency of a change.
It controls the overall lifecycle and state flow of the change.

• Normal – follows the complete lifecycle (Assess → Authorize → Implement → Review)

• Emergency – fast-tracked to handle urgent issues

• Standard – pre-approved, low-risk, repeatable changes

In short, Change Type answers “how urgent or risky is this change?”

Change Model

Change Model was introduced by ServiceNow to support a fit-for-purpose and fit-for-use approach.

Earlier, all changes of a given type followed the same approvals and process, regardless of what was actually changing (application, network, server, etc.).

With Change Models, you get flexibility:

• Different approval flows

• Different tasks

• Different automation

• Based on CI, CI class, or business context

For example:

• A Network Change can require Network + Security approvals

• An Application Change may only require App Owner approval

• A Server Reboot can be modeled as an Emergency

• An Application Deployment can be modeled as Normal

A single Change Type can have multiple Change Models.
