6.11, looks like cash comes in and is handled by employee A, who gives it to the treasurer? or sends it to the bank? but then also at the same time sends the remittance advice or verification to the controller who records the cash in the ledger or subsidiary journals, all in all, I think the point is to separate duties, sure, but also to prevent the people who control the asset from being the same people who record the asset

found this

looks like someone other than the controller has to review as well? seems like that would be the controller... 

6.12, same thing, because then it would increase inherent risk, they would be tempted because they could ...or rather, they'd have the power to manipulate cash, they could record a different amount and no one would know

6.13, 

6.14, I'm guessing sequentiality
