How can use Kanban board in RTC?

Hi.
Nowadays I'm studing about  Kanban.
Concept of Kanban is somewhat understood. but I wonder how to apply in RTC.
At my workplace, project members work with FUNCTION POINT in the development environment.
I think this FP element can be used as KANBAN's backlog.

1. I would like to know if there is a case that applies FP concept to Kanban.
2. In general, if someone have a manual (Admin/User) or related information on kanban in rtc, I would appreciate it if you share.
