Root cause analysis can be hard. Really hard.
You might wonder why I’m saying this. After all, there are proven methodologies available: Fishbone diagrams, 5 Whys, Fault Tree Analysis, Pareto charts, etc.
Yet I see the same pattern repeatedly: teams stop at symptoms, not true root causes.
❓Why does this happen?
Two forces drive it.
🔹Time pressure → Teams want the problem fixed so they can move on.
🔹Second, unconscious bias → Finding the true root cause often means uncovering systemic gaps that require real effort to fix. It’s easier to patch the technical issue and close the ticket. When you’re a subject matter expert, your technical depth can become tunnel vision. You’re so focused on the trees that you can’t see the forest. That expertise narrows your view of the bigger systemic problems.
I understand it. It’s human. But it’s costly.
The problem resurfaces later, and you end up spending far more time fixing the systemic issue you could have addressed upfront.
The pattern I see most:
A technical failure reveals a procedural gap or missing control. The initial root cause analysis misses it. The team fixes the technical symptom but leaves the process weakness intact. Months later, the issue returns in a different form. I’ve seen production lines halt and costly recalls repeat because teams stopped at the technical fix.
❓How do you break the cycle?
✅ Keep asking “why.” Push the root cause team past the technical layer.
✅ Challenge them: Is this still a symptom? What systemic or process-level issue is driving this failure?
In one program, we were facing recurring software-related recalls year after year, resulting in cost of non-quality, and the team’s increased workload in addressing these issues.
Instead, I asked them to pause and to go deeper.
The root cause analysis revealed fundamental gaps in our software development and testing process.
We built an improvement program around those insights. Within months, recalls stopped.
The most persistent quality and compliance problems come from process gaps, not isolated technical errors. If you don’t address the system, you’re managing recurring failures instead of preventing them.
This works regardless of methodology. The principle stays the same. Push past the first answer.
🎯 Find the true root cause.
