I have not opened up the slides. But form what I read it looks like Clerk Responsibility must be assigned to the Clert user and Manage Responsibility must be assigned to the Manager user. We cannot assign Manager Responsibility to both Manager user and Clerk user. How we build the Clert responsibility is a different matter. We can build Clerk menu from scratch (more work, however wlil offer efficient custom navigation) or we can build it using exclusions on Manager menu (less work, however may not offer efficient navigations).
