When a Presentation Is the Correct Choice
A presentation is the stronger format when understanding must be constructed progressively. It is particularly effective when the audience needs to hear why a problem matters, examine the evidence in a deliberate order and arrive at a decision after the reasoning has been established.
That makes presentations suitable for investment pitches, technical briefings, classroom teaching, strategic reviews, project approvals, sales meetings and sensitive organisational discussions. In each case, delivery is part of the information. Tone, pacing, emphasis and audience reaction can alter how the message is received.
Guy Kawasaki’s famous 10/20/30 rule—ten slides, twenty minutes and a minimum thirty-point font—was developed as a discipline for business pitches rather than a universal law. Its lasting value lies in the pressure it places on presenters to prioritise, shorten and stop using slides as teleprompters.
A strong presentation should therefore:
Begin with the decision, not the software
Before opening PowerPoint, define what the audience should believe, approve, reject or do after the presentation. A deck without a desired outcome becomes a collection of slides rather than an argument.
Build a visible narrative
Each slide should create a reason for the next one. The audience should understand where it is in the argument, what has been established and what remains unresolved. Sequence is the presentation’s primary advantage; wasting it on disconnected slides is unforgivable.
Make one dominant point at a time
This does not require every slide to contain one object, but every slide should have one unmistakable job. A chart, image and headline may work together, provided they communicate the same point.
Use charts to make a claim
A chart is not automatically informative simply because it contains data. The title should state the finding, the scale should be honest, irrelevant categories should be reduced and the important comparison should be visually identifiable.
Design for the room
Fonts, line weights and labels that look acceptable on a laptop may disappear on a projector. The presentation should be tested from the distance at which the audience will actually see it.
