problem 1:

Why is it significant that a department other than Purchasing Department must raise a purchase requisition?

problem 2:

Even with the separate Purchasing Department (i.e. separate from the department which raises the purchase requisition), there is still a risk of fraud through staff in Purchasing Department. In what way could a fraud happen, and how could controls be instituted to reduce the risk of such the fraud?

problem 3:

Why is each purchase invoice not sent with goods to Goods Received Department?

problem 4:

Why should the Goods Received Department not admit goods where there is no purchase order?
