Old Fashioned Definition of Root Cause vs. Modern Definition of Root Cause

November 29th, 2016 by

NewImage

When we first started the development of TapRooT® back in the 1980s, we developed this definition of a root cause:

Root Cause
The most basic cause (or causes)
that can reasonably be identified 
that management has control to fix
and, when fixed, will prevent 
(or significantly reduce the likelihood of)
the problem’s recurrence.

The modern definition of a root cause, which was proposed in 2006 by Mark Paradies at the Global TapRooT® Summit and really isn’t so new, is:

Root Cause
The absence of best practices
or the failure to apply knowledge
that would have prevented the problem.

 This modern definition of a root cause leads to this definition of root cause analysis:

Root Cause Analysis
The search for the best practices
and/or the missing knowledge that
will keep a problem from recurring

Since most people (including, in the past, me) say that root cause analysis is the search for why something failed, this reversal of thinking toward looking for how to make something succeed is truly a powerful way of thinking. The idea changes the concept of root cause analysis.

Even though a decade had passed since proposing this new definition, I still have people ask:

Why did you change the definition? I liked it like it was!

Therefore, I thought that with the new TapRooT® Books coming out, I would explain our reasoning to show the clear advantage of the modern definition.

The modern definition focuses on the positive. You will search for best practices and knowledge. You aren’t looking for people to blame or management faults. Yes, a best practice or knowledge is missing, but you are going to find out how to do the work more reliably. Thus, the focus is on improvement … the opportunity to improve vision!

The same thing can be said about the old fashioned definition too. But the old definition focused on cause. The difference in the definitions is a matter of perspective. Looking up at the Empire State Building from the bottom is one perspective. Looking down the Empire State Building from the top is quite another. The old definition looked at the glass as half empty. The new definition looks at the glass as half full. The old definition focuses on the “cause.” The modern definition focuses on the solution.

This shift in thinking leads people to a better understanding of root causes and how to find them. When it is combined with the Root Cause Tree® and Dictionary, the thinking revolutionizes the search for improved performance.

The concept of looking for ways to improve has always been a part of the TapRooT® System. It is the secret that makes TapRooT® such a powerful tool. But the modern definition – the new perspective – makes it easier to explain to others why TapRooT® works so well. TapRooT® is a tool that finds the missing knowledge or best practices that are needed to solve the toughest problems.

One last note about the modern definition: In the real world, absolutes like “will prevent” can seldom be guaranteed. So the root cause definition should probably be augmented with the additional phrase: “or significantly reduce the likelihood of the problem’s recurrence.” We chose not to add this phrase in the definition to keep the message about the new focus as strong as possible. But please be aware that we understand the limits of technology to guarantee absolutes and the ingenuity of people to find ways to cause errors even in well-designed systems.

That’s the reasons for the definition change. You may agree or disagree, but what everyone finds as true is that TapRooT® helps you find and fix the root causes of problems to improve safety, quality, productivity, and equipment reliability.

Happy Thanksgiving

November 24th, 2016 by

Here is my Thanksgiving posting. I post it every year, lest we forget…

NewImage

In America, today (Thursday) is a day to get together with family and friends and reflect on our blessings – which are many!

One of my ancestors, Peregrine White, was the first child born to the Pilgrims in the New World.

During November of 1620, Peregrine’s mother Susanna, gave birth to him aboard the ship Mayflower anchored in Provincetown Harbor. His father, William, died that winter – a fate shared by about half of the Pilgrim settlers.

The Pilgrims faced death and the uncertainty of a new, little explored land. Why? To establish a place where they could worship freely.

With the help of Native Americans that allied with and befriended them, they learned how to survive in this “New World.” Today, we can be thankful for our freedom because of the sacrifices that these pioneers made to worship God in a way that they chose without government control and persecution.

Another interesting history lesson about the Pilgrims was that they initially decided that all food and land should be shared communally. But after the first year, and almost starving to death, they changed their minds. They decided that each family should be given a plot of land and be able to keep the fruits of their labors. Thus those that worked hardest could, in theory, reap the benefits of their extra labor. There would be no forced redistribution of the bounty.

The result? A much more bountiful harvest that everyone was thankful for. Thus, private property and keeping the fruits of one’s labor lead to increased productivity, a more bountiful harvest, and prosperity.

Is this the root cause of Thanksgiving?

This story of the cause of Thanksgiving bounty is passed down generation to generation in my family. But if you would like more proof, read the words of the first governor of the Plymouth Colony, William Bradford:

“And so assigned to every family a parcel of land, according to the proportion of their number, or that end, only for present use (but made no division for inheritance) and ranged all boys and youth under some family. This had very good success, for it made all hands very industrious, so as much more corn was planted than otherwise would have been by any means the Governor or any other could use, and saved him a great deal of trouble, and gave far better content. The women now went willingly into the field, and took their little ones with them to set corn; which before would allege weakness and inability; whom to have compelled would have been thought great tyranny and oppression.”

William Bradford, Of Plymouth Plantation 1620-1647, ed. Samuel Eliot Morison (New York : Knopf, 1991), p. 120.

What You May Not Know About Mark Paradies, President of System Improvements

November 14th, 2016 by

 

P1020482

As a TapRooT® User, you probably know that Mark is one of the co-creator’s of the TapRooT® Root Cause Analysis System and a co-author of the TapRooT® Book series. You have probably heard that he has all sorts of experience with root cause analysis and incident investigation. But did you know that …

Mark is a Certified Professional Ergonomist (CPE).

He was the 85th person to be certified in ergonomics and human factors by the Board of Certified Professional Ergonomists. Mark has worked extensively on projects to improve human performance and reduce human errors. 

His Masters Degree research at the University of Illinois was focused on the proper roles of operators and automation for the next generation of nuclear power plants (human factors function allocation).

Before starting System Improvements, he worked on projects to improve aspects of human performance including procedures usability and usage, and operator, maintenance, and technical training.

He also developed systems for managing performance improvement in a resource limited environment.

He used his human factors knowledge and experience to build into the TapRooT® System the ability to analyze and fix human performance/human behavior issues.

Mark was in Admiral Rickover’s Nuclear Navy (a High Reliability Organization).

Mark has studied high reliability organizations. But Mark has one major advantage over most of those who do academic research and speak about high reliability organizations … He has worked in a high reliability organization – the Nuclear Navy (the original high reliability organization). Therefore, he knows what works, why it works, and what doesn’t work BECAUSE HE HAS BEEN THERE. He understands Admiral Rickover’s management systems and practical methods to guard against normalization of deviation.

Mark has a unique understanding of process safety.

Marks has two engineering degrees (BSEE and MS Nuc E), human factors training, and experience working in Admiral Rickover’s Nuclear Navy (where he achieved his Engineer Certification). This gives him a unique understanding of process/nuclear safety. He has written about this experience (see this LINK) and provided talks for companies interested in improving their process safety systems and senior management understanding of process safety. (See part of his Summit talk in 2012 HERE.)

Mark has developed trending techniques for infrequently occurring safety and quality data.

Mark used the work of statistical experts Dr. Donald Wheeler, Dr. Walter Shewhart, and W. Edwards Deming to develop techniques to find statistically valid trends of infrequently occurring accident data. Mark is working on a new book about performance measurement and trending that will be published in 2017. Watch for the next trending course based on his work being held prior to the 2018 Global TapRooT® Summit.

Mark has practical experience.

In his spare time between working for high reliability organizations (the Nuclear Navy and Du Pont) and leading System Improvements, Mark designed and built roads (driving a bulldozer, track loader, excavator, and dump trucks), produced hardwood lumber from trees, and helped design two houses. While working in college getting his  BS in Electrical Engineering, he was a field supervisor (in actual agricultural fields) and a cable TV installation and repair man. While still in high school, Mark worked in agricultural jobs, construction, retail, and ran his own lawn mowing and landscape business.

That’s a little more about the lessor known facts about Mark’s experience and expertise. If you have questions for Mark or would like him to consult with you about your improvement efforts, contact him at this LINK, or call 865-539-2139.

Arturo de la Garza Guajardo, Safety Guru and TapRooT® Instructor

November 5th, 2016 by

Arturo de la Garza died last July after a long career improving safety and many years teaching TapRooT®.

Arturo was one of our first clients outside the US. Linda and I taught a course for him for the safety people at Cydsa in Monterrey, Mexico. 

Arturo was a Chemical Engineer and had lost of chemical plant experience including plant management before joint Cydsa’s corporate staff.

When Arturo retired from Cydsa, he went to work for Cemex and then left Cemex to become one of out contract TapRooT® Instructors. For over a decade he taught courses for SI in Mexico and South America until he was 80 years old.

We will miss his good humor and knowledge and we know that all the instructors who taught with him and clients with whom he shared his knowledge will miss him as well.

Navy Root Cause Analysis Focused on Blame Vision, Crisis Vision, or Opportunity to Improve Vision?

November 3rd, 2016 by

NewImage

In a short but interesting article in SEAPOWER, Vice Admiral Thomas J. Moore stated that Washing Navy Yard had just about completed the root cause analysis of the failure of the main turbine generators on the USS Ford (CVN 78). He said:

The issues you see on Ford are unique to those particular machines
and are not systemic to the power plant or to the Navy as a whole.

Additionally, he said:

“…it is absolutely imperative that, from an accountability standpoint, we work with Newport News
to find out where the responsibility lies. They are already working with their sub-vendors
who developed these components to go find where the responsibility and accountability lie.
When we figure that out, contractually we will take the necessary steps to make sure
the government is not paying for something we shouldn’t be paying for.”

That seems like a “Blame Vision” statement.

That Blame Vision statement was followed up by statement straight from the Crisis Mangement Vision playbook. Admiral Moore emphasized that would get a date set for commissioning of the ship that is behind schedule by saying:

“Right now, we want to get back into the test program and you’ll see us do that here shortly.
As the test program proceeds, and we start to development momentum, we’ll give you a date.
We decided, ‘Let’s fix this, let’s get to the root cause, let’s get back in the test program,’ and
when we do that, we’ll be sure to get a date out. I expect that before the end of the year
we will be able to set a date for delivery.”

Press statements are hard to interpret. Perhaps the Blame and Crisis Visions were just the way the reporters heard the statements or the way I interpreted them. An Opportunity to Improve Vision statement would have been more along the lines of:

We are working hard to discover the root causes of the failures of the main turbine generators
and we will be working with our suppliers to fix the problems discovered and apply the
lessons learned to improve the reliability of the USS Ford and subsequent carriers of this class,
as well as improving our contracting, design, and construction practices to reduce the
likelihood of future failures in the construction of new, cutting edge classes of warships.

Would you like to learn more about the Blame Vision, the Crisis Management Vision, and the Opportunity to Improve Vision and how they can shape your company’s performance improvement programs? The watch for the release of our new book:

Monday Accident & Lessons Learned: UK RAIB Report on Derailment at Paddington Station in London

October 10th, 2016 by

NewImage

Summary from the UK Rail Accident Investigation Branch …

At 18:12 hrs on Thursday 16 June 2016, a two-car diesel multiple unit train, operated by Great Western Railway (GWR), was driven through open trap points immediately outside Paddington station and derailed. It struck an overhead line equipment (OLE) mast, damaging it severely and causing part of the structure supported by the mast to drop to a position where it was blocking the lines. There were no passengers on the train, and the driver was unhurt. All the the lines at Paddington were closed for the rest of that evening, with some services affected until Sunday 19 June.

Monday Accident & Lessons Learned: Overspeed at Fletton Junction

September 19th, 2016 by

This incident notice is from the UK Rail Investigation Branch about an overspeed incident at Fletton Junction, Peterborough on 11 September 2015.

At around 17:11 hrs on 11 September 2015, the 14:25 hrs Virgin Trains East Coast passenger train service from Newcastle to London King’s Cross passed through Fletton Junction, near Peterborough at 51 mph (82 km/h) around twice the permitted speed of 25 mph (40 km/h). This caused the carriages to lurch sideways resulting in minor injuries to three members of staff and one passenger.

It is likely that the train driver had forgotten about the presence of the speed restriction because he was distracted and fatigued due to issues related to his family. Lineside signs and in-cab warnings may have contributed to him not responding appropriately as he approached the speed restriction and engineering controls did not prevent the overspeeding. Neither Virgin Trains East Coast, nor the driver, had realised that family-related distraction and fatigue were likely to be affecting the safety of his driving. Virgin Trains East Coast route risk assessment had not recognised the overspeeding risks particular to Fletton Junction and Network Rail had not identified that a speed limit sign at the start of the speed restriction was smaller than required by its standards.

Screen Shot 2016 08 01 at 4 32 25 PM

The incident could have had more serious consequences if the train had derailed or overturned. The risk of this was present because the track layout was designed for a maximum speed of 27 mph (43 km/h).
As a consequence of this investigation, RAIB has made five recommendations. Two addressed to Virgin Trains East Coast relate to enhancing the management of safety critical staff with problems related to their home life, and considering such issues during the investigation of unsafe events.

A recommendation addressed to Virgin Trains East Coast and an associated recommendation addressed to Network Rail relate to assessing and mitigating risks at speed restrictions.

A further recommendation to Network Rail relates to replacement of operational signage when this is non-compliant with relevant standards.

RAIB report also includes learning points relating to managing personal problems that could affect the safety performance of drivers. A further learning point, arising because of a delay in reporting the incident, stresses the importance of drivers promptly reporting incidents which could have caused track damage. A final learning point encourages a full understanding of the effectiveness of safety mitigation provided by infrastructure and signalling equipment.
