To identify opportunities to improve the efficiency of the organization's procurement process, the internal auditor needs to understand the current state of the process and gather detailed insights from those directly involved. Reviewing the procurement process map with employees who carry out key activities allows the auditor to understand the practical aspects of the process, identify any inefficiencies or bottlenecks, and obtain valuable suggestions for improvements from those who are most familiar with the daily operations. This approach ensures that the information gathered is relevant, practical, and actionable.
