How To Use CMMS To Supplement Root Cause Analysis

How To Use CMMS To Supplement Root Cause Analysis

According to the American Society of Quality (ASQ), a root cause is defined as “A factor that caused a nonconformance and should be permanently eliminated through process improvement. The root cause is the core issue—the highest-level cause—that sets in motion the entire cause-and-effect reaction that ultimately leads to the problem(s).”

As most of you already know, Root Cause Analysis (RCA) is a systematic process for identifying the origins, or root cause, of problems and determining an approach to minimize or eliminate their risk of recurrence. It focuses on preventing problems at the source rather than resorting to a firefighting approach and being reactive every time. RCA tries to be more scientific about asset failures, going one step beyond troubleshooting. [Read more…]

Root Cause Analysis Framework

Root Cause Analysis Framework

Guest Post by Jignesh Padia (first posted on CERM ® RISK INSIGHTS – reposted here with permission)

Albert Einstein once said that … “Insanity is doing the same thing over and over again and expecting different results.” If you find yourself doing a root cause analysis on the same problem repeatedly, it may be time to revisit the root cause analysis from a framework point of view rather than as a tool.  In this article, I will review an example of root cause analysis as a risk management framework. This is different than examining one of the tools or processes you use for troubleshooting a problem.

There are several root cause analysis frameworks that you may come across. In my research, the top five root cause analysis frameworks related to healthcare are from the:

  • Canadian Patient Safety Institute (CPSI)
  • Institute for Healthcare Improvement (IHI)
  • National Health Service (NHS), the Joint Commission
  • World Health Organization (WHO). [Read more…]

Introduction to the Essential Characteristics of an RCA Program

Introduction to the Essential Characteristics of an RCA Program

This is the first in a nine-part series of articles. This first one will lay out what I think are essential characteristics of an RCA program. The other articles will follow up on each of the items in some detail.

RCA Templates Again

RCA Templates Again

RCA Templates Can Be Used

In my last article,  RCA Templates Use or not?, I discussed templates and suggested that while beneficial for many things, they may not provide as much value for those doing RCA’s.  This is because for any specific effect, the variability in the cause tree is significant and difficult to predict.  This doesn’t mean that there are no options to utilize templates to help speed up the process, but perhaps not in the way that people might be used to.

When Smart TV Content Delivery Fails, Who is to Blame?

HDTV chainA Crisis in the Home IT department

If you are the head of your home IT department, you may relate to this tale

Last night my wonderful wife Stacy was riddled with angst over the disruption of her binge watching a spy series, a mild crisis with our own IT hardware.

The cause of her disappointment was the failure of our new large screen Ultra High Definition (UHD) Smart TV to deliver a drama series with a reasonable picture and sound quality. [Read more…]

Don’t Stop Your RCA Investigation Too Soon

Don’t Stop Your RCA Investigation Too Soon

The problem

Recently there was a power outage, that caused approximately 2,000 homes to lose power during a very cold day.  The paper headline read, “All-day outage caused by worn wiring”.

This seems like a reasonable comment and probably like many other newspaper headlines also seems to go a long way to explain what caused the 2,000 homes and business to lose power for 5 ½ hours, and the 300 that lost power for a total of 11 ½ hours. [Read more…]

Basic Reliability Definition

Occasionally, I like to step back and reflect on reliability in basic terms.

In that spirit, the basic premise of reliability is usually stated as “The probability that an item will perform a required function, without failure, under stated conditions, for a stated period of time.”

To use the reliability equation, the definition of failure must be defined, so you can tell if your equipment has indeed failed.  This way you can include it in the MTBF (Mean Time Between Failure) calculation.

After you have defined a failure and recorded them appropriately, you can plug the numbers into the reliability equation, R = e ^-(λ*t)  where λ is the failure rate which is defined as λ= 1/MTBF and come up with an objective value for the reliability. [Read more…]
