“Have you tried the Five Whys?”
It’s usually the first thing people reach for when something goes wrong.
And to be fair, it’s not a bad instinct.
You’re trying to move past symptoms and get to the real cause. That’s exactly the right goal.
But here’s what I’ve seen over and over again.
Teams use the Five Whys… and still end up fixing the wrong thing.
Not because the tool is broken. But because of how it’s used.
Why the Five Whys Feels Right
It’s simple.
Start with a problem, ask “why” repeatedly, and eventually you land on a root cause.
Example:
Clean. Logical. Easy to follow.
But here’s the issue.
Real-world problems don’t behave in straight lines.
In practice, most failures don’t come from one chain of causes.
They come from multiple conditions lining up at the same time.
Let’s take that same example and look a bit closer.
The bearing failed
Now ask yourself: Which “why” do you pick?
If you follow just one path, you ignore the others.
And that’s how you end up with actions like:
Meanwhile, contamination is still getting in.
Load conditions are still not understood.
The problem comes back.
The Five Whys assumes:
But in most industrial environments:
That’s a very different problem to solve.
It’s the difference between:
Once you see that, you can’t unsee it.
I’m not saying throw it out.
Used well, it’s a great thinking tool.
But it needs a slight shift.
When you ask “why,” allow for more than one answer.
If two things contributed, capture both.
That alone improves the quality of your thinking.
This is where most Five Whys exercises quietly fall apart.
People fill in the blanks with what they believe.
Instead, ask:
If you can’t answer that, it’s a hypothesis, not a cause.
Instead of going straight down a single chain, start building sideways.
You’ll end up with something closer to a cause-and-effect map than a list.
That’s where the real insight starts to show up.
Walk it through step by step.
If someone unfamiliar with the problem can’t follow it, there are gaps.
And those gaps are usually where repeat failures hide.
If your RCA typically ends with:
There’s a good chance the Five Whys didn’t go far enough.
Those are often outcomes, not underlying causes.
When teams move beyond a basic Five Whys approach, a few things change:
It’s not more complicated. It’s just more structured.
Most people aren’t doing RCA poorly on purpose.
They’ve just never been shown what “good” looks like beyond a simple tool.
That’s exactly why this guide exists:
“My Boss Told Me to Do an RCA, Now What?”
It takes the thinking behind tools like the Five Whys and builds it into a clear, practical approach you can actually use on real problems.
Inside, you’ll see:
It’s the step most people are missing after learning the Five Whys.

The Five Whys is a good starting point.
But it’s not the finish line.
If you’ve ever walked away from an RCA thinking, “We did this already… why is it happening again?”
There’s a good chance the problem wasn’t effort. It was structure.
And once you fix that, everything else gets easier.
