I think the 5 steps is too "high school" and overrated for the adult world. Sometimes there is no time nor audience patience for cliches like "how you're going to tell them" and "how you told them". Intro, content, what's next. That's all that matters.

That's why I said "as a starting point."

The five paragraph form itself is a beginner's tool: any good essay will deviate.

However, one nugget to borrow from the five paragraph form is the centrality of the thesis statement. Having a thesis for your talk is _crucial_ IMO. It doesn't have to explicitly stated, and it could be as simple as "I'm going to convince you that $FEATURE is awesome," but you need a focal point. You could restate what I'm saying here as honing your elevator pitch for you talk or in any number of different phrasings, but the idea is the same: a short statement that sums up the absolute core idea of your talk and provides a focus for you and your audience. Anything that doesn't fit your thesis is a good candidate for trimming.
