In a meeting or presentation, on the phone, over video, or in person, welcome questions when you are the expert/speaker/presenter.
Let people know that you are open to questions (rather than saying "Hold your questions until the end."), and when you get one, resist saying "Good question". "Good question" is an old trick for buying time. When a speaker says it each time, it is clearly insincere, and if a speaker says it often, it sounds like judgement of the question or person.
Here are three steps to effective question answering:
1) Use "Th..." words when someone asks a question. Saying "Thanks for asking" or "That's something I've explored" gives acknowledgement and appreciation for the interaction.
2) After that, address the inquiry directly and clearly.
3) From there, ensure you did, in fact, answer the question by asking "Did I provide what you were seeking"? or "Was that information what you wanted?", or "Did that answer provide what you sought?", or "Did I answer your question?". These confirming questions allow the person making the inquiry to ask more and/or confirm that you provided what was sought.
If you don't know the answer to a question, state that, write it down, and give a time and day when you'll have the answer for the person. Allow others to know if they want the answer, too, to provide their contact information to you for being copied on the answer. And then, research the answer and provide it by the time you offered!
Questions are a way for you to engage, grow and learn in presenting, so welcome the ask, and provide answers professionally for impact!
