Preparing for an audit

Answer: I'm not sure what do you mean by "live auditing" but I'll assume you are referring to normal on-site audit.

Regarding its execution, since it focuses on observing the person responsible while he performs his jobs, the auditor has to be well prepared and informed about the process being audited, so he can quickly identify and ask activity related questions. Additionally, since this kind of audit practically happens at live environment, you should take measures to avoid the audit may impact on production (e.g., avoid as much as you can the execution of emergency procedures for example).

So, in short, you should consider to ask and study the process documentation previously, take notes on critical activities sequences to be performed, and think about questions to ask like "why this kind of activity is performed?" and "why this kind of activity is performed in this sequence?" (these questions can help you verify if people performing the activity understand w hat is being done and why).
