A talk is rehearsed and timed. Q&A is not, and for a technical audience it's often where the real value of the session shows up — or where a speaker loses the room they'd just won.
Three kinds of questions, three approaches
- The genuine follow-up ('how did you handle X'): answer directly and briefly — this is the easy case.
- The 'well actually' from someone showing expertise: acknowledge the point honestly, correct only if they're factually wrong, and move on without ego.
- The question you don't know the answer to: say so plainly, offer to follow up, and move on. Guessing confidently and being wrong costs more credibility than admitting the gap.
Protecting the room's time
Repeat the question aloud before answering — half the room usually didn't hear it — and set an expectation upfront ('let's do five more questions') so one long thread doesn't crowd out everyone else waiting to ask something.
