Write what the audience should understand or decide after the presentation. Then create slide headlines that form the argument without design.
Under each headline, add only the evidence needed to support it. Remove sections that do not change the conclusion.
Build a rough version with plain layouts first and test whether the headlines form a coherent story. This is a practical review sequence, not a universal formula for every presentation. Check numbers, sources, timing, and the final requested action before improving transitions or illustrations.
A 20-minute starting sequence
Write one audience sentence, five to seven headline slides, and one evidence note under each. Mark unknown data rather than interrupting the outline with research. Then read only the headlines: they should make sense as a short argument.
Ask for early feedback on the storyline when a decision owner needs to confirm the direction. Treat that review as a test of scope and logic, not a guarantee that the final deck will be approved.
Continue with bad first draft and ask for early feedback.
