What & why

What it is
A brief, focused presentation typically lasting 3-7 minutes that delivers key information or ideas with maximum impact and minimal time. Lightning talks require exceptional organization, clear messaging, and dynamic delivery to maintain audience attention and achieve objectives quickly. This format is increasingly important in fast-paced business environments and conference settings.
Why it works

Working memory holds only a few items at once, so a five-minute talk built around a single takeaway respects that ceiling instead of overrunning it. The tight format forces you to strip context and lead with the point, which front-loads the part listeners remember. Time pressure also reads as confidence and respect for the audience, and the brevity itself tends to keep attention high because there is no slack for minds to wander.
