Regulators Don’t Fix Your Problems, You Do – NERC Cause Analysis Introduction

Nerc

Regulators from many industries require root cause analysis of process failures, but not all approaches to RCA reflect best practices for requiring or even identifying a proper investigation. A few require compliance with highly structured reporting systems designed to support consistency, tracking, and validating research, such as NERC and DOE Cause Codes. Regulations can set expectations, but they don’t create excellence. 

Best-in-class organizations don’t run by striving to meet regulatory requirements; that is often only a starting point.  They learn from adverse events in a disciplined way that far exceeds external expectations. Proper RCA of equipment failures is one of those pieces. When regulators drive problem identification, it can signal that internal processes need strengthening.  

1. Take the Equifactor® Equipment Troubleshooting & TapRooT® Root Cause Analysis Training to investigate failures properly. 

2. Get to the Equipment Reliability and Maintenance Excellence track at the Global TapRooT® Summit to see how Best-In-Class organizations use Equifactor® Equipment Troubleshooting to eliminate those failures. Keep calm and TapRooT® on.

Interactive Introduction to Root Cause Analysis gives us a great intro to what ends up as ACA.

Yep, there’s way more than one root cause, and typical fixes just deal with foliage.
Much better to remove the roots!
Single-root-cause fallacy. Here we go!

What’s the difference between Apparent Cause Analysis and Root Cause Analysis? Foliage vs roots.

Awesome! That’s exactly what ACA and ACE are!
Aaaaaaaand, they call a culture of pressure and burnout THE root cause of the Challenger explosion…

“Once you ask that first ‘why’, you’re potentially starting down a narrow path.” A narrow path of confirmation bias, “the fastest way to validate the conclusion you’ve already jumped to” as one TapRooT® leader puts it (Cory Wald)! Using 5-whys, you risk losing the big picture, as NASA did, and missing a LOT of relevant and useful details, like NERC did when identifying THE root cause of the Challenger incident.

Fixing apparent causes is just like mowing the lawn. It stimulates the real issues to grow stronger!

Oh geez, “you’re about to witness an event.”

Congratulations NERC, you’ve identified an Apparent Cause! We can now blame the A+ technician!
“Summary of what we’ve learned”, judgmental language of the A+ tech.
NERC here expresses judgmental language rather than facts. An equivalent statement: “A+ tech made a quick buck, regardless of the fatality risk. He knew better and still made a dangerous choice.”

Welcome to Earth, North American Electric Reliability Corporation! Correcting missing best practices and human error, regardless of motivations, is what RCA is designed to do.

SMH, although moving the box is ONE good corrective action.
Ed looks so happy and not-electrocuted in this picture! Glad we fixed that money-loving contractor!

Here’s the full story NERC provided in SnapCharT® form. The A+ tech only has one Causal Factor, and there are three.

There seems to be a Management of Change and many other issues involved, not explicitly called out. We can see easily that this evidence leads to no fewer than five root causes, with just the evidence NERC provided here.

Causal Factor 1: Tech left the old power box in the location

  • Equipment Difficulty – Design – Environment not considered (snowy location)
  • Training – continuing training NI (A+ Tech didn’t know weather)
  • Corrective Action NI – Client chose not to install a new weatherproof box in a higher location

Causal Factor 2: Client switched off the wrong breaker

  • Labels NI – similar to old system labels

Causal Factor 3: HM did not check for the power off

  • LOTO NI – did not personally verify breaker was off

Let’s do a better job at identifying ALL the missing best practices. Whether you’re the contractor (A+), the client (Mrs. Muller), or a NERC-subject company (Ed’s organization, it seems), there are ways YOU can prevent each of these human errors from leading to a shock. You can only fix what you control.

Change Analysis and Barrier Analysis (Safeguard Analysis) are techniques to build a SnapCharT® (Event and Causal Factors Chart)
