Presentation planning begins with the change you want in the audience, not with opening slide software. Define what listeners should understand, decide, feel confident about, or do afterward. Then analyze what they already know, what they value, what may concern them, and what authority they have.
Constraints shape the plan. A ten-minute decision briefing, a forty-minute teaching session, and a portfolio walkthrough need different depth and interaction. Reserve time for questions, identify the minimum essential evidence, plan accessible alternatives, and prepare for technology failure without designing two completely different presentations.
