You may find some useful info
here on further "probing questions".
A useful distinction is between
closed and
open questions. Try Googling for closed questions vs open questions & you should find a lot.
Closed question = one where a single response usually 'closes' the exchange, because it can be answered by just a yes/no or a fact. eg:
- Are you British?
- Are you an employee or contractor?
- Does company policy permit smoking in office buildings?
Open (or open-ended) questions = ones that open up an exchange, invite further information. Good auditors use a lot of open-ended questions! eg:
- Could you tell me more about how that works?
- What is the usual practice when that occurs?
- How does that help achieve the outcome?
Note that both are required, eg, there are times when you
want to ask closed questions (Is your correct address 1234 High St?) and other times when open-ended questions are needed.
Nervous interviewers/inexperienced auditors often ask too many closed questions, and not enough open ones.
