Case, Case Task, and Catalog Tasks all have a checklist function. If you would like to know more about the functionality, you can look at the Official ServiceNow documentation.
In order to use a checklist, you need to be on an item that allows them. Cases will be the most common example of this. Please keep in mind that checklists are not linked to the completion of a ticket. You can put a checklist on a ticket but the ticket can be closed regardless of the progress of the checklist.
On the Case below, we have scrolled just under the Short Description and Description fields where we can see four tabs 'Notes', 'Resolution Information', 'View Restrictions', and 'Checklist'. Where the Case is brand new and not yet saved, Checklists won't show up. If you want a checklist on a new Case, fill it out, 'Save and Stay', and Checklists will be functional.
Clicking on Checklist will show us the Checklist tab. From here, we can click the blue arrow and 'Create new' item.
We can create multiple items on the Checklist. In order for Checklist items to save, you need to hit 'Update' or 'Save and Stay' on the ticket.
As agents complete the items, they can cross the items off. Checked off items can be unchecked.
Checklist progress will be sent to the Activity list.
There are two ways to create a template for Checklists.
