Zenith Retail plc's board notices that store managers can raise purchase orders, approve supplier invoices and authorise payments for their own stores. Which internal control component is most directly weakened by this arrangement?

Segregation of duties is weakened. When one manager raises orders, approves invoices and authorises payments, no independent check exists, so errors or fraud can go undetected. This is a failure of control activities, not of monitoring, market risk assessment or shareholder communication.

  4. DInformation and communication to shareholders

Explanation

One person controls the initiation, approval and payment stages of the purchasing cycle, so no independent check exists. This is a failure of segregation of duties, a core control activity. Monitoring and external reporting do not address the root weakness of combined incompatible duties.
