Thinking Like an Analyst

Post 3: Barrier Thinking—Even When Nothing Went Wrong


Sharpening the Saw Series


What if your best root cause tools could help you prevent problems, not just solve them?


If you've been trained in cause analysis, you’ve used barrier analysis to understand how and why things went wrong. But here’s the secret: the most effective analysts don't wait for a failure to start thinking about barriers.


They apply barrier thinking daily—during observations, planning, conversations, and walkdowns—to reduce risk and reinforce reliability.


Let’s talk about how you can do the same.

It also helps to "Flip the Script". Ask yourself what is your definition of exactly what is "Corrective Action"? Are you correcting an Event or do you want to improve performance that has not yet resulted in an Event? Are you correcting AFTER the fact or trying to PREVENT an adverse consequence? After you have thought about what barriers failed that should have protected you from an Event, ask what barriers were in the way of achieving the outcome you desired? The two questions have opposite polarity. Don't just focus on Barriers to Failure but also Barriers to Success. Barriers can cut both ways; they can either prevent you from being successful (hampered your Performance) or FAIL to protect you from an adverse consequence.

Does Root Cause Analysis Put Blame on the Individual?

When something goes wrong at work—an equipment failure, a safety incident, a missed target—there’s often a familiar, knee-jerk reaction:

“Who’s responsible?”


But Root Cause Analysis (RCA) challenges that impulse. It asks us to go deeper—not to assign blame, but to understand what really happened and why. The goal isn’t retribution. The goal is prevention.


A Systematic Approach to Understanding Problems

Root Cause Analysis is a structured, evidence-based method for identifying the underlying causes of events—not just their symptoms. At its heart, RCA is about understanding organizational and programmatic drivers, not about pointing fingers.


Unlike informal debriefs or disciplinary reviews that focus on who made a mistake, RCA investigates the systems, processes, tools, and culture that allowed the failure to occur.
