Example of an Internal Auditor Job Description

Meet Lisa, an internal auditor at XYZ Pharmaceuticals, a mid-sized pharmaceutical company.

Example of Lisa’s Work as an Internal Auditor:

Recently, XYZ Pharmaceuticals has implemented a new automated system for tracking and managing its extensive inventory of pharmaceutical ingredients and finished products. The system was costly to implement and is critical to the company’s operations.

Lisa’s task as an internal auditor is to conduct an audit of this new system to ensure it is functioning as intended, the data it produces is accurate and reliable, and that it’s been effectively integrated into the company’s operations.

  • Planning: Lisa starts by planning her audit. She identifies key functions of the inventory management system that need to be reviewed, such as how inventory quantities are tracked, how data is recorded and stored, and how the system interfaces with other financial systems at XYZ Pharmaceuticals.
  • Data Gathering: Lisa interviews individuals who use the system daily—this includes warehouse staff, supply chain managers, and financial analysts. She observes the system in operation and reviews user manuals and system specifications.
  • Data Analysis: Lisa tests a sample of transactions in the system to ensure they are accurately recorded and reflected in the system’s reports. She checks to see if system access is appropriately restricted to prevent unauthorized changes to inventory data. She also validates that the system’s reports are accurately incorporated into XYZ’s overall financial statements.
  • Reporting: Lisa finds that the new system is generally functioning well, but she discovers a flaw in how it records transfers of inventory between warehouses, which could lead to inaccuracies in inventory counts. She also finds that access controls could be strengthened to further reduce the risk of unauthorized changes.
  • Follow-up: Lisa writes a report detailing her findings and presents it to senior management. The report outlines the issues she discovered and provides recommendations for improvement. Management agrees to implement her recommendations and asks Lisa to conduct a follow-up audit in six months to ensure the issues have been addressed.

Through her work, Lisa helps XYZ Pharmaceuticals improve its operations, reduce risks, and ensure the accuracy of its financial statements. This is an example of the valuable role that internal auditors play in organizations.
