Circle A-1 contains a role with accountabilities that mention roles that exist in circle A-2. For example: +WidgetQA in circle A-1's accountability reads "Answering inbound emails while looping in +WidgetDesign" where +WidgetDesign exists in circle A-2.
I'm unclear if it is acceptable to do this. Should the two circles have an acute understanding of each other's internal roles, such that they appear in accountabilities? If not, what can be done to fix this accountability?
