Guide
The PREP method for impromptu speaking, with a worked example
By the Imprie team at MONDev Studio · · 6 min read
When you're put on the spot, the hardest part isn't knowing what to say. It's knowing what order to say it in while you're still thinking. PREP gives you that order before you need it: Point, Reason, Example, Point. This guide shows how long each part should take in a two-minute answer, what PREP looks like next to a typical rambling answer to the same question, and the mistakes that undo it.
The four steps, timed for a 2½-minute answer
Imprie gives you up to two and a half minutes per answer. Most strong answers use a little less, about two minutes, which leaves room to breathe. Here's roughly how that time splits:
P10–15 seconds
Point
Your answer, in one sentence. Not the background, not "great question". If someone stopped listening after this line, they should still know what you think.
R20–30 seconds
Reason
Why you think it. One reason said well beats three said quickly; if you have more, pick the one your listener cares about most.
E60–75 seconds
Example
One concrete case: a moment, a number, a name. This is where most of your time goes, and where answers become memorable.
P10–15 seconds
Point
Say the point again, ideally sharper than the first time, tied to what you just showed. This is your landing; stop after it.
Notice the shape: the two Points are short and the Example is long. People who "know" PREP but still ramble usually have it the other way round, with a long build-up to the point and a rushed, abstract example.
Why point-first works when you're nervous
Under pressure, most people narrate their thinking in the order it happens: context, then doubts, then the answer. That's natural, but it makes the listener wait, and nerves make the wait longer. Leading with the point fixes three things at once:
- Your listener knows where you're going, so everything after it sounds like support rather than wandering.
- You've done the hardest part first. Once the point is out, the reason and example are easier to find, because you're explaining something you've already said.
- If you get cut off, you've still answered. In interviews and meetings, that happens more than you'd think.
A worked example: the same question, two answers
The prompt below is one of the topics in our Debate & Pushback practice set. Both answers were written by the Imprie team to illustrate the method; they're examples, not transcripts of real users.
"Is it better to be the first or the best? Pick one and defend it."
Example A · The ramble
"So, um, I guess it really depends, because being the best is obviously important too, and there are lots of companies that were first and then, like, failed, I can't remember the names right now, but anyway, at my last job we had this app, and the designers wanted more time for the onboarding, and honestly I understood that, but I kind of pushed to ship the first version without it, and people weren't happy, but it worked out because we got feedback earlier, so yeah, I'd say first, probably."
What happened: the answer ("first, probably") only arrives in the last few words, and it's hedged. The reason is squeezed in at the end, the opening example is vague ("I can't remember the names"), and there's no concrete evidence the real one worked.
Example B · PREP
P "Be first, because being first is how you find out what 'best' actually means.
R Until real people use something, 'best' is only a guess about what they need.
E At my last job, I shipped our app's first release without the redesigned onboarding the team wanted. Two weeks of real usage showed people weren't dropping off at onboarding at all. They were dropping off at the first permission request, which the redesign hadn't touched. We moved the design time there instead.
P Being first didn't stop us becoming the best; it showed us where 'best' needed to be."
What changed: the answer is the first sentence, with no hedging. One reason, one specific example with what was learned, and a closing point that sharpens the opening instead of repeating it.
Example B is also shorter: about 45 seconds spoken, versus a minute for A. Structure usually saves time rather than costing it, and the spare time can go into a richer example.
Four mistakes that undo PREP
1. A point that's really a topic
"There are pros and cons to both" is a topic, not a point. A point can be disagreed with: "Be first." Test yours by asking whether someone could reply "I don't think so".
2. Three reasons instead of one
Listing reasons feels thorough but sounds like hedging, and it eats the time your example needs. Choose the reason your listener would find most convincing. You can keep the others for follow-up questions.
3. An example that's another reason
"For example, early feedback is always valuable" isn't an example; it's a second reason. A real example has a when, a who or a number in it.
4. A closing point that starts a new topic
The final Point should land the first one, not open a fresh idea. If you notice yourself adding "and another thing", stop and restate your opening line instead.
Other shapes for the same skill
PREP is the most general structure, but a few close relatives fit some questions better. Imprie's feedback suggests whichever suits your answer:
- Story → message: for "tell me about a time" questions. Tell the moment briefly, then say what it taught you. The message is your point, delivered at the end on purpose.
- Contrast: "Most people think X; I've found Y." Useful when you're pushing back or reframing a question.
- Point → reason → example → takeaway: PREP with a forward-looking finish ("so next time, I'd…"). Good for interviews, where the listener wants to know what you'd do, not just what you did.
Practise it: a three-day drill
- Day 1: answer three Debate & Pushback topics and only worry about the first sentence. Is it a point?
- Day 2: three Pitching & Persuasion topics. Keep the reason to one sentence and spend the time on a concrete example.
- Day 3: three Storytelling topics using story → message. Finish on the message and stop.
Use the free practice timer for each one and answer out loud. If you want to know whether your point really came first, and how your pace and filler words held up, that's exactly what the Imprie app measures, along with one clear next step after every answer.
