Finding the Root Cause of Your Broken Parts with the Lightning Problem Solving Method
Who Knew It Was This Easy?
Today, we’re tackling the always-frustrating issue of broken parts. If you’re putting out manufactured parts that break on a regular basis, it can cost you a whole lot more than just time. Frustration, money, and even your job could be on the line, unless you use the Lightning Problem Solving Method! The road to problem-solving with broken parts can be a bit bumpy. In this video, we’ll learn how to avoid potholes on the journey to your root cause. It’s as easy as breaking it down into five simple steps.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_video link=”https://youtu.be/t7esayfo5rs” title=”Broken Parts, 5 Steps to Solve FAST!”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]“In a manufacturing setting, if you’re putting out parts that are breaking on a regular basis, it can mess up a whole lot more than just your day.” Share on X
The road to problem-solving with broken parts can be a bit bumpy. In this video, we’ll learn how to avoid potholes on the journey to your root cause. It’s as easy as breaking it down into five simple steps.
#1: You’ll need to collect ten parts: five broken parts, and five in good shape.
Most engineers start by looking at only the broken parts. What a slow way to solve problems! This method won’t help you find the root cause – it only develops a temporary solution. Parts will continue to break. You’ll keep wasting time and money.
“Here’s where a lot of engineers go wrong: they look ONLY at the broken parts and ask, ‘how can I re-engineer this so we don’t get broken parts again?’” Share on X(Pro-tip: If you’re guilty of “solution-hunting,” you can check out my video on root cause vs solution. The best problem solvers know the difference between a solution and a root cause!)
Your good parts should be some that have been in that assembly or a similar scenario for a long time that haven’t broken. If you can’t find parts like these, then just find five parts from the assembly line – work with whatever you have.
#2: Ask the right questions.
“Instead of asking HOW can I re-engineer this so it doesn’t break, ask WHY 5 times.” Share on XFinding the root of the problem is all about changing your perspective. You might be asking, “How can I re-engineer this part not to break?” You should be asking “Why?” Shout it into the sky. Why? Why? Why? Why? WHY?!!
I kid. But in all reality, asking yourself why five times could make five times the difference. Here’s an example:
- Why do we have these scrap parts? Because the operator didn’t follow the work instructions.
- Why didn’t the operator follow the work instructions? It was because he wasn’t trained properly.
- Why wasn’t he trained properly? Well, because we don’t have somebody in charge of training.
- Why not? Because unfortunately there isn’t enough funding to hire a single employee for that one job.
And so on!

#3: Check the specification of the parts.
You’ve asked all the right questions to get the big picture. So now it’s time to get technical. Think of yourself as the Goldie Locks of manufacturing problem-solving. Look at your parts and ask, is this one too small? Too big? What about the dimensions and color? It all should be just right.
#4: Check your processes.
We’re all human, but you want your employees trained to follow processes to a T.
“Remember, you want your employees trained to follow the process similar to the way a programmed robot would.” Share on X
#5: Reproduce the event.
Finally, you’ve gotten to the fun part. We get to break things! The final step in solving a manufacturing issue with broken parts is to break them again – only this time, in a controlled environment.
After the first four steps, you should have a good idea of what your root cause could be. Now is your opportunity to test your theory. If you found mistakes in the processes or specifications, run new parts mimicking those mistakes. Then, run more new parts the correct way. If you see contrast (broken vs. unbroken), then you got it right!
“If the three parts that you made the good way do not fail and the three parts that you made bad fail, then most likely you have the root cause.” Share on XIn conclusion, if you’re stuck with a broken part problem that you need to get under control fast, get in touch!
