If someone wants to find something out, or needs to approve or verify something, it can be done online with their system access as proof of their authority. People do not have to ask someone else to query the system and a piece of paper is not signed when they could have approved it online.
8. One main process
There is one main process which is adhered to for the majority of the volume. Any other processes are used because they are valid alternatives where a conscious decision was made to process the volume in this way (people are not just allowed to do what they want).

All are process variations but are for acceptable reasons.
