Audition question:

revised question: topic: segregation of duties: which documents do I track to keep authorization, custody, recording and reconciliation separate. please explain segregation of duties.

please explain me segregation of duties as an internal control (authorization --- custody --recording --reconciliation). in order to rest control what activities, documents and internal control needed for sales

I don't understand how this question is violating academic integrity as I needed explanation how segregation of duties works. in that case, every question a student post can be a violation.

anyways, my question is how segregation of duties works. I understand if same person is responsible for authorization, custody, recording and reconciliation can cause error or fraud. but as an auditor, which documents do I track to keep authorization, custody, recording and reconciliation separate. please explain segregation of duties.

P.S.: It's not an assignment question. it's for my understanding. thank you.
