Case-Based Questions \u2013 Manufacturing Departments (CIA Part 1 Style)<\/strong><\/p>\n

 <\/p>\n

Case 1: Unauthorized Purchase<\/strong><\/p>\n

 <\/p>\n

During an internal audit of the procurement process, the auditor observed that several purchases of raw materials were made without an approved Purchase Order (PO). The materials were received and recorded in inventory based only on supplier invoices.<\/strong><\/p>\n

 <\/p>\n

Question<\/strong><\/p>\n

 <\/p>\n

Which control weakness is MOST evident in this situation?<\/strong><\/p>\n

 <\/p>\n

A. Lack of vendor evaluation<\/strong><\/p>\n

B. Absence of purchase authorization control<\/strong><\/p>\n

C. Ineffective production scheduling<\/strong><\/p>\n

D. Poor inventory valuation method<\/strong><\/p>\n

 <\/p>\n

\u2705 Answer: B. Absence of purchase authorization control<\/strong><\/p>\n

 <\/p>\n

The purchase order approval process ensures purchases are authorized and necessary. Buying without PO increases risk of fraud, duplicate purchases, or unauthorized procurement.<\/strong><\/p>\n

 <\/p>\n

Case 2: Inventory Discrepancy<\/strong><\/p>\n

 <\/p>\n

During a warehouse audit, the internal auditor noticed that the physical inventory count of raw materials was significantly lower than the quantities recorded in the inventory system. Investigation revealed that materials were frequently issued to production without a Material Requisition Note (MRN).<\/strong><\/p>\n

 <\/p>\n

Question<\/strong><\/p>\n

 <\/p>\n

Which control should be implemented to reduce this risk?<\/strong><\/p>\n

 <\/p>\n

A. Increase production capacity<\/strong><\/p>\n

B. Require authorized material requisition before issuing materials<\/strong><\/p>\n

C. Reduce supplier lead time<\/strong><\/p>\n

D. Increase marketing budget<\/strong><\/p>\n

 <\/p>\n

\u2705 Answer: B. Require authorized material requisition before issuing materials<\/strong><\/p>\n

 <\/p>\n

Case 4: Segregation of Duties Issue<\/strong><\/p>\n

 <\/p>\n

During an audit of the purchasing cycle, the auditor observed that the same employee creates purchase requisitions, approves purchase orders, and records supplier invoices.<\/strong><\/p>\n

 <\/p>\n

Question<\/strong><\/p>\n

 <\/p>\n

Which internal control principle is being violated?<\/strong><\/p>\n

 <\/p>\n

A. Budgetary control<\/strong><\/p>\n
