What are the tasks need to be done in creating user roles

What exactly do you want to achieve?

Is this in Appian or a system like JIRA? Not sure what you're asking for.

I just wanted to add some points (Tasks) in my user stories named "USER ROLES" what needs to be done in future development

Yes its kind of Jira

Its difficult to understand what exactly you need. Do you need some details for creating a user story in Jira?

Here is something that might be of some use to you - community.appian.com/.../appian-scrum-board-asb---scooby

Yes

Thanks

Well, the Appian forums aren't exactly the place for help on systems that aren't Appian. I'd look up the documentation of the system you are using.
