I passed the RMP and had never seen a Monte Carlo run


The Proactive Risk PM Weekly

Issue #26

June 29, 2026

Hi ,

Four months after I earned my PMI-RMP®, I still had never seen a real Monte Carlo simulation actually run.

I knew what it was. I could define it. I answered questions about it on the exam. Triangular distribution, three-point estimates, probability distributions.... I had all the vocabulary.

But I had never watched one work.

A friend of mine, someone else in the PM space, finally pulled one up and walked me through it. I sat there watching the information populate, seeing the P50 and P80 numbers generate, and I had this weird double reaction.

Impressed. And kind of underwhelmed at the same time.

Because I had built Monte Carlo up in my head into something massive. Some complex, PhD-level crystal ball that only Fortune 500 risk teams with massive budgets could access.

And what I was actually looking at was... a really smart decision-making tool. A good one. But just a tool.

That moment stuck with me.

Now, let's get Proactive Over Reactive!

"You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing — that's what counts. I learned very early the difference between knowing the name of something and knowing something."

~Richard Feynman

 

The Problem With How We Teach This Stuff

Here's the thing, that four-month gap shouldn't exist.

If you earn the PMI-RMP® or even the PMP®, you should leave understanding Monte Carlo as a tool, not just as a definition.

But that's not how most courses work.

Monte Carlo gets explained theoretically. You learn what it is. You learn when to use it. You answer the exam question.

And then you never actually see one!

I see this every time I teach my RMP® Exam Prep. My students come in having studied Monte Carlo. They know the vocabulary. But the moment I ask them to picture what a Monte Carlo output actually looks like, what it tells you, how you read it, what decisions you make from it, you can see the uncertainty on their faces.

That's not their fault. That's a gap in how risk management gets taught.

So I did something about it.

Using Claude, I built a free Monte Carlo simulator at riskreadypm.com, nothing fancy, just intentionally simple... designed specifically to show students what Monte Carlo looks like and how it actually works. Not for enterprise use. Not a replacement for professional tools. Just a way to make sure no one leaves my course having only heard about Monte Carlo without ever seeing it run.

When I pull it up in class now, I watch the lightbulb go on. Every time.

Not just about Monte Carlo, but about the fact that this "intimidating" tool is actually something they can understand, use, and talk about confidently with their stakeholders.

That's the moment I was trying to create.

Dad Joke of the Week

Why did the project manager run the simulation 10,000 times?

Because once just wasn't a confident enough estimate.
