Final answer:
Reviewing count sheets and inventory printouts alone is not sufficient to fully understand inventory shortages. A comprehensive assessment including processes, sales forecasting accuracy, and interviews is necessary to identify potential systemic issues or irregularities.
Step-by-step explanation:
Reviewing the count sheets, inventory printouts, and memos from the last inventory count would not be sufficient to address the audit objective regarding the cause of inventory shortages. Since the company's products are subject to rapid obsolescence with little scrap value, it is essential to look beyond the year-end numbers and assess the inventory management processes throughout the year, such as how reorder decisions are made, sales forecasting accuracy, and the effectiveness of the restocking system. Moreover, considering that the sales force is highly incentivized with commissions, it would be prudent to examine the potential for sales order manipulation.
The company's current inventory count performed by an external auditor is a snapshot in time; therefore, it is necessary to establish whether discrepancies are due to systemic issues such as theft, improper record-keeping, or deficiencies in inventory control mechanisms. Continuous monitoring and analysis of inventory trends, as well as interviews with staff, including the VP of Sales and the sales team, could offer valuable insights into inventory turnover, obsolescence rates, and any possible irregularities that may lead to stock variances. This comprehensive approach allows the auditor to ascertain the underlying issues causing the inventory shortages.
