Has your organization adopted Six Sigma? Lean manufacturing?  What about Lean Six Sigma?  If you already have any of these business process improvements in place, where will you go next? In this article we will focus on transforming your organization beyond Lean Six Sigma to the next level of performance.

  Can you identify and name this fracture pattern? How can you tell it is that fracture pattern? Where are the origin(s) of the failure on the fractured surface? How can you tell where the origin(s) are?

This failure occurred on a turbine driven boiler feedwater pump (TDBFP) at a fossil fuel power plant. The pump in question is an outboard boiler feed pump. Plant is operating normally when unexpectedly pump shuts down and causes a forced outage. Here is a basic process flow diagram for this process…

This is a failed shaft that came out of a pump in a paper mill. The pump was only in service for about a month before it failed unexpectedly…

In our last series highlighting the 4 primary Failure Modes (FM) of component failures (erosion, corrosion, fatigue and overload), we discussed how to read fractured surfaces. In this follow-up series, we will take a look at tips on how to collect, preserve and examine such failed components. I will reiterate my intent to make this series, as with the others, as

“Failure Mode and Effect Analysis” (FMEA) and “Root Cause Analysis” (RCA) are becoming commonplace terms in work environments and in the literature. This article will demonstrate that these terms, while seemingly generic references to regulatory compliance, actually elicit various interpretations from individuals. Therefore, applications of FMEAs and RCAs will be equally disjointed, along with the inconsistency of the analysis results.

In this blog, I discuss the RCA definition I used as a career analyst/investigator and explain why it makes sense to me. You decide if it makes sense in your facility. RCA is so ill-defined that no matter what people use to solve problems at their facilities (i.e.- troubleshooting, brainstorming, problem-solving or scribbling on a bar napkin)…they will call it

There are various ways for us to improve our root cause analysis and take our reliability to the next level. Reliability professionals could do RCAs on a napkin, using kraft paper and post it notes, or utilizing fancy software. In the end, the analysis is only as good as the analyst! I have seen some pretty bad ‘RCA’s documented in

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?

Chapter 1: Is All RCA the Same? An RCA myth shared by many managers is that RCA methods are all the same, when in fact they are NOT. The range of what constitutes an effective RCA method is vast. Some RCA techniques have minimal emphasis on establishing all the ways a problem can occur.  Others provide a more comprehensive set

Safety is often directly correlated with system or component reliability. Is that really the case? Find out what the experts and their data really says.

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
