Last week I gave a lightning talk about my experiment with Test Driven Development.
It’s available on Vimeo here.
The format I chose was 20 slides, auto-advancing every 20 seconds. I’d sort of practiced with this format beforehand, but it was much different on the day. Here’s what I learnt:
- Doing a talk with such a strict time constraint is a bit like running a race. You end up going much faster than you did in training. There’s a lot of adrenalin and I felt like I had much more time than I’d anticipated. Next time I will practice to a real audience beforehand to try and create this.
- Usually in a talk I try to slow down (I’m aware I talk quite quickly at the best of times), but this format meant I didn’t attempt this. Watching the video back I can see that I started out too quickly but I think I relaxed into it after a few slides (another parallel with running!)
- Standing in front of a room full of people is something I usually try to avoid. However I was so focused on keeping within the time I managed to overlook this fear!
- Next time I would make sure I had some visual cue in front of me to know how much time I have left on each slide. I definitely spent too much time looking up at the screen to talk about my slides, when I didn’t really need to – most of the time the slide content was just there to back up my point. I didn’t need to keep referring to it.
I really enjoyed the experience and am looking forward to doing another lightning talk!
