Observation and interview
With questions in hand, the internal auditor should monitor the employee performing a given process, preferably in a natural scenario (i.e. the task needed doing that day). Asking the employee questions about the process they are performing will give the auditor insight as to whether or not the member of staff is, a) following the process properly and, b) understands the process and the risks it is designed to mitigate.
Depending on the answers, the auditor can make note of areas that may need refresher sessions, or aspects of the process that may not have aged well, such as inefficient practices.
Report write-up
With the observation and interview process complete, the internal auditor needs to write-up their findings and highlight any areas of concern. Again, the report document can be as simple or as detailed as you require, as long as the findings are recorded. In the event of a process found to be non-compliant, the auditor will need to recommend further measures in an action plan.
They may also need to raise a Non-Compliance Report, depending on your company and its quality compliance measures and recognitions:
