I’ve written a lot about planning and preparation, but there is also tremendous value in having the skill and poise to rise to the occasion when someone springs an unexpected question on you or asks you to say a few words on a particular topic. Having survived (so far) 21 years in front of trainees, I’ve developed a few habits that have served me well.
Plan for the unexpected. This sounds like an oxymoron; how can you prepare for an impromptu talk? If you’re going to a meeting, think about who will be there, and based on your knowledge of their history, their positions and their stake in the topic, what might they ask? To be really sure, don’t limit yourself to the scheduled topic. You might be there to discuss a particular project, but someone might have an interest in one of your other projects as well.
Practice situational awareness. Have you ever had the feeling of looking up and seeing all eyes turned on you? It’s easy to tune out or check your email momentarily when someone else is speaking on a topic that doesn’t immediately concern you—and that’s when Murphy’s Law guarantees that someone will direct a question to you. There’s nothing more credibility-crushing than having to ask someone to repeat the question.
