I tend to write about all things Root Cause Analysis (RCA). I come from a background that engrained a holistic view of Reliability Engineering into me. This involved equipment, process and human Reliability. I write about the following types of RCA topics:
1. The Definition of ‘RCA’ and Why I Think the Current Term is Useless
2. When Should RCA’s be Conducted? Addressing the Application of RCA Proactively versus Reactively
3. What’s the Difference Between Root Cause Analysis and Shallow Cause Analysis? Why Do ‘RCA’ Efforts Fail
4. The Critical Task of Evidence Collection and Preservation to an Effective RCA
5. The Correlation Between Reliability/RCA and Safety, Does Such a Correlation Exist?
7. The Measurement of an RCA System’s Effectiveness
8. The Creation of an RCA Knowledge Base and its Sustained Growth to Store ‘Corporate Memory’ and Leverage Using AI
Properly conducted RCAs are time and resource consuming, so when we are not getting the expected ROI’s from our efforts, we have to consider why are we wasting so much money doing the same thing over and over again? This article will focus on the commercial and process aspects of RCA, that can take away from their effectiveness on the corporate bottom-line and impact the safety of our co-workers.

Does procedural and/or regulatory compliance with RCA guidelines ensure Operational Reliability? Does it ensure improved Safety? Operational Reliability involves the aggregation of Equipment, Process and Human Reliability methods and techniques.
What is the difference between troubleshooting, problem solving and ‘RCA’? Are the outcomes different when we use The 5-Whys, The Fishbone or a Logic Tree/Causal Factor Type Tree?

In recent years, “Defect Elimination” has become a hot topic in the reliability world. But what exactly does defect elimination mean? How does it differ from other maintenance practices? Is it more than just a new way to describe planned and predictive maintenance? This article will seek to answer these questions in a very practical manner.

An undesirable event occurs (fancy term for unexpected failure) a Root Cause Analysis (RCA) is triggered. This usually means what occurred is a severe event as triggers are often set pretty high (i.e. – reportable injury/fatality, equipment damage in excess of x-thousands of dollars, production losses in excess of x-thousands of dollars, regulatory violation, etc.). Since there is urgency and visibility, how do I decide who will lead the investigation/RCA? Our natural tendency is to identify the technical ‘expert’ in the nature of whatever the undesirable event was. But does that typically produce the most effective outcome for the organization and its employees? This article will focus on which skills are needed most, under such conditions, and why
I used to be on Facebook many years ago in an effort to keep up with old friends. However, I began to realize the forum was often used to create an illusion that someone wanted their community to have about them. I knew many of these people creating such illusions, that is how I know they were ‘illusions’. Their ‘Facebook Family’ simply was not their reality.
This is not a paper about the pro’s and con’s of social media forums such as Facebook, but more about our propensity to create illusions, or prisms in which we want others to view our work initiatives. While I could apply this concept to many personal and business situations, I’m going to limit it to our general views of Reliability, Maintenance and to a degree Safety (as a by-product of effective Maintenance and Reliability).

WE LOVE OUR POST-ITS!
When I’m asked who our primary competitors are, I quickly and simply reply ‘Post-Its’ (full-disclosure, ‘Post-Its’ are a registered trademark of the 3M corporation)!
It’s hard to imagine anyone who hasn’t been in a conference room at some point in their career, utilizing colorful, adhesive post-its to help express some form of a logical thought process. Whether it be for brainstorming, process mapping, Reliability Centered Maintenance (RCM) or some form of Root Cause Analysis (RCA), we have become avid fans of post-its to help us produce graphical expressions of our thoughts…WE LOVE POST-ITS!

Most of us have all worked at places with some degree of an ‘RCA’ effort. They likely all defined and practiced ‘RCA’ differently, but nonetheless they had something called RCA.
What made one facility better at it than another? Why was one facility’s RCA more effective than another?

If managers knew what the overall power of a well supported Root Cause Analysis (RCA) effort meant for their bottom-line, they would be breaking down doors to implement the process.
Unfortunately, this is often not the case, so this paper is an attempt to educate such individuals about the characteristics of an effective RCA methodology. The paper focuses on the three aspects of RCA we believe leadership teams need to understand the most. [Read more…]
![Is There Really a Direct Correlation Between Reliability & Safety?[Updated]](https://lucas-accendo-site-speed.sprod01.rmkr.net/wp-content/uploads/2021/12/Clocher.Saint_.Menoux.3300x300T-150x150.png)
Safety is often directly correlated with system or component reliability. Is that really the case?

During a recent webinar I presented with SMRP, entitled “Root Cause Analysis: It’s a Money Maker, Not a Money Taker”, I was fortunate to have many deep thinkers in my virtual audience.
They floated some questions related to conducting ‘RCA’s on non-mechanical situations. To my fellow veterans in this RCA space, this is a relatively easy question to properly address, but it did get me to thinking. I think those of us who do this for a living, take for granted that we know a properly facilitated RCA, can apply to any undesirable outcome, no matter the industry or the bad outcome.

Think about it: when is RCA typically requested and applied in our environment? Based on my experience, it is typically requested and applied when:
RCA and How to Understand the Basics of Component Failure
When performing a PROACT® Root Cause Analysis (RCA) there is a data collection step called ‘Preserve’ (or the PR in the PROACT acronym) which requires the team to collect failed parts, conduct interviews, obtain paper data and positional information after an undesirable event occurs.
[Read more…]So what does it mean to be ‘safe’? Is a company ‘safe’ because they have not had an OSHA recordable injury in say over a one year period? Does that mean they will continue to be ‘safe’ in the next year? Does it mean they are at a higher risk of an incident in the near term, because they weren’t safe…but lucky? These are the debates I read about online and as an outsider, I can see both sides. But there has to be a practical middle ground as Safety and Reliability depend on each other for their individual successes, they are interdependent.

Oftentimes, Production may not know the value of using Reliability tools such as Opportunity Analysis (OA) and Root Cause Analysis (RCA) to gain more consistent predictable production runs.
Most production leadership has never spent time in Maintenance and/or Reliability roles; therefore, they see a different big picture. The pieces of the big picture are interconnected like a puzzle and most production people see the puzzle assembled one way, while the Maintenance and Reliability people see the puzzle assembled another way.
