Abstract:
I recently posted an i-Presentation on Reliabilityweb.com that
evoked an unexpected resounding response from viewers. This
i-Presentation was entitled “The Essential Elements of Root
Cause Analysis”. The interesting aspect about this type of
response was that the majority of submittals also responded with
comments to the presenters. It became apparent from these
comments that most people are looking for the basics about what
a Root Cause Analysis effort is and where do my efforts rate.
As
a provider myself, these results showed me that we in the
business tend to be too close to our methodologies and as a
result use language that mostly only Root Cause Analysis
veterans can decipher. We are missing the point when it comes
to the “blocking and tackling” fundamentals of a Root Cause
Analysis effort and what those face who must research the
topic. They likely find confusion about what they read about
Root Cause Analysis in the marketplace. This article is meant
to convey these basics to those that find themselves in the
position of mapping out a path forward to establish their new
Root Cause Analysis efforts.
EVERYONE SAYS THEY DO ROOT CAUSE ANALYSIS AND THEY ARE NOT
LYING!
The term Root Cause Analysis can be traced back to the great
philosophers of our time. However, the term today is likely much
more confusing than the term back then. This is because there
are so many different Root Cause Analysis methodologies on the
market that it is difficult to know which ones are right for
which situations.
Many people today use the term Root Cause Analysis as if it is
universally understood. They use it as if there is a standard,
or universally accepted methodology. Make no mistake, there is
no such universal methodology. Root Cause Analysis is a noun,
and all the brands on the market are adjectives describing that
noun.
Everyone says they do Root Cause Analysis, and none of them are
lying. Because there is no universally accepted methodology,
there is no universally accepted definition! Therefore we can
all apply whatever methodology we wish in our facility and call
it Root Cause Analysis.
This paper is meant to look at Root Cause Analysis from the
standpoint of what the fundamentals are of a true Root Cause
Analysis process. Notice that we did not say Root Cause
Analysis methodology, but a Root Cause Analysis “Process”. Many
believe that using a Root Cause Analysis tool like the 5-Whys, a
Fishbone Diagram or a Logic Tree constitute a Root Cause
Analysis effort. Life would be much simpler if this were the
case. Unfortunately, in the world we live in today, we must
consider the environments in which we work and how these
environments can help or hurt our good Root Cause Analysis
intentions.
Throughout this paper, keep the parallel in your mind between a
police detective and a Root Cause analyst. The roles are very
similar, the primary difference being the environments in which
the analysts work. The analytical processes used by both are
the same. Let’s explore these fundamentals.
THE TOP 10 FUNDAMENTALS OF A ROOT CAUSE ANALYSIS EFFORT
-
Establishing Management Support
-
Training
Qualified Analysts and Team Members
-
Consistently Determining When Root Cause Analysis is to be
Applied
-
Correctly
Defining the Event
-
Using
Cause-And-Effect: Tightly Coupled Logic
-
Collecting Evidence: Establishing Facts
-
Drilling
Down to Understanding Bad Decisions
-
Tracking
Return-On-Investment (ROI)
-
Measuring
Root Cause Analysis Effort Effectiveness
-
Creating
a Knowledge Management Database
Let’s explore each of these in a little more depth:
-
Establishing Management Support.
Management support starts with an agreement in principle on
the concepts and benefits of Root Cause Analysis to the
organization. In most cases a Root Cause Analysis effort is
born when a progressive executive chooses to be a Champion
or Sponsor for the effort. Just like a Root Cause Analysis
analyst, the best ones will be those that WANT to do it, not
HAVE to do it. Management support is not merely “lip
service” but it is “walking the talk” with actions.
Evidence of serious management support of a Root Cause
Analysis effort involves:
-
Writing a “fat” check to support the Root Cause Analysis
effort.
-
Management attending abbreviated training on how to
support the Root Cause Analysis effort they have chosen
-
Establishing a Root Cause Analysis policy for the
organization. This makes it a requirement to do Root
Cause Analysis under certain circumstances as opposed to
doing it when we want to.
-
Establishing a Root Cause Analysis procedure for the
organization. This outlines the specific conditions
that trigger a Root Cause Analysis to be conducted, how
to define the event, the process to be followed, the
pre-requisites of the analyst and team members and how
recommendations will be handled.
-
Providing incentives for Root Cause Analysis personnel
such as tying their Root Cause Analysis results to their
performance evaluations.
-
Providing technical resources for analysts to help prove
their hypotheses.
-
Ensuring that Root Cause Analysis recommendations get a
fair shake in the work order system (as opposed to being
back burner items forever).
-
Setting up tracking systems to monitor performance of
the effort from a corporate perspective.
-
Training Qualified Lead Analysts and Team Members.
Pre-requisites should be established for who is qualified to
lead teams and who is qualified to participate on teams.
Oftentimes organizations feel that Root Cause Analyses are
purely engineering exercises and therefore do not require
hourly personnel on the teams. This is simply not the
case. The sharp end personnel, those closest to the work,
will likely know more about any given failure on the floor
than their superiors. It is our contention that Root Cause
Analysis CANNOT be done without the participation of the
hourly personnel. Qualified Lead Analysts will learn that
their role is to be a facilitator not a participator. This
is sometime hard to grasp as our natural tendency after a
failure is to assign the technical expert as the lead
analyst. Unfortunately, the technical expert is sometimes
too close to the event and may have a bias where they have
something to lose or gain by the outcome.
-
Consistently Determining When Root Cause Analysis is
to be Applied. A
properly written Root Cause Analysis procedure should
clearly outline what triggers a Root Cause Analysis to be
conducted in a facility. Depending on how progressive the
organization is, will determine if Root Cause Analyses are
only required on high visibility sporadic events (reactive
use of Root Cause Analysis) or will Root Cause Analyses be
conducted on the more chronic type of events (proactive)
which are potential precursors to the catastrophes. Many
often do not realize as well that Root Cause Analyses can be
done on failures that have not occurred! Root Cause
Analyses can be done proactively on hi risk events
identified in a Failure Modes and Effects Analysis (FMEA).
How? We simply treat the hi risk events as if it did happen
and work backwards to understand all the factors that have
to be in place for the consequences to occur. By
identifying the root causes in this manner, we will
implement recommendations that will reduce the chances that
those causes will be triggered.
Non-Injury Trigger Example in a Root Cause
Analysis Procedure
A
Root Cause Analysis shall be requested for events/incidents with
a total cost (maintenance, operations and lost profit
opportunities) greater than $25,000. Listed below are several
examples of such events:
Unpredicted Failure
Property Damage
Lost Production
Safety Incidents
Quality Incidents
-
Correctly Defining the Event.
Many believe that Root Cause Analysis investigates
incidents, but we really investigate negative consequences.
For instance, if a pump were to fail (with no back up), many
would consider that to be the event to analyze. However,
when we look closer, we find that we are not analyzing this
because the pump failed; we are analyzing this because a
process was shut down as a result (consequence). Think
about it, if there is no negative consequence to a failure,
would we realistically do Root Cause Analysis on it?
-
Using Cause-And-Effect: Tightly Coupled Logic:
Brainstorming causes is not using cause-and-effect as
related to an incident. Picking cause categories such as
Communications, Training, etc. is not using
cause-and-effect. Cause-and-effect is tightly linking
factors that led to an undesirable outcome and using hard
evidence to back it up.
-
Collecting Evidence: Establishing Facts
If an analyst is not collecting evidence to support every
one of their hypotheses (their case), they are not doing
true Root Cause Analysis. Allowing hearsay to fly as fact
is not a valid form of evidence. Root Cause Analysis
conclusions should be based on solid evidence and not who is
the loudest person in the room. If we use our detective
analogy, how well would a detective fare in court if his
case was based on hearsay?
-
Drilling Down to Understanding Bad Decisions. Analysis processes that stop at the
identification of physical root causes (component level)
lack depth. Analyses that focus on people that make bad
decisions are often called “witch hunting” expeditions.
True Root Cause Analysis will seek to understand why good
people make bad decisions. Why did the person who made the
decision think it was the right thing to do at the time? In
this case we are searching for their situational awareness
and trying to understand all the circumstances they faced
that forced the decision.
-
Tracking Return-On-Investment (ROI).
As is the
case with any investment, we want to know what our return
is. Root Cause Analysis is no different. If the execs have
written a “fat” check, they will want to know if their money
was well spent. As we all can relate, we constantly have to
justify our existence in the form of demonstrating our
value. The Root Cause Analysis effort is the same as we
must demonstrate our results in the form of dollars to
justify the continuance of the effort.
-
Measuring Root Cause Analysis Effort Effectiveness.
ROI is only one measure of effectiveness.
However, our Root Cause Analysis efforts should be further
measured as to how they contribute to the Key Performance
Indicators (KPI’s) of the corporation. It is vital to
demonstrate this linkage as it will make the attainment of
these goals dependent on the task of Root Cause Analysis.
This further helps to justify the existence of the Root
Cause Analysis effort.
-
Creating a Knowledge Management Database.
Conducting a successful Root Cause Analysis and
then putting it into a filing cabinet should be a crime.
The greatest benefit any corporation can get from their Root
Cause Analysis efforts is to raise the knowledge, skill and
awareness of their employees to issues identified in a Root
Cause Analysis. This is because we do not want other people
to make the same triggering decisions that caused the
previous failures to occur. Aggregating Root Cause Analysis
results into an easily searchable database for lessons
learned is imperative to the success of any Root Cause
Analysis effort.
As you can tell from these brief descriptions of the fundamentals,
few of the basics relate directly to the skill of the lead
analyst and their choice of a tool. The majority relate to
external support issues necessary for a Root Cause Analysis
effort to be successful (not a Root Cause Analysis, but a Root
Cause Analysis effort). A true Root Cause Analysis effort is
usually much more than a person who is good at solving problems
using their tool of choice. Our visions should include many
people possessing these skills and therefore increasing safety
across the corporation, while improving productivity and
profitability.
Root Cause Analysis, when used properly, is a form of “corporate
memory”. Think about when the re-engineering era was passing
through. Corporations began to downsize by offering attractive
early retirement packages. Who took them? Employees who were
confident that they could easily get another job AND collect
severance. This left a huge void of experience in the workplace
when they left. This is because problems would occur in which
they knew how to solve, but no one else did.
Think if we were able to use Root Cause Analysis so efficiently and
effectively that turnover was not as big an issue. This is
because we would go to our Root Cause Analysis knowledge base
and be able to see how the experienced people thought through
the problems and solved them. As the honorable Martin Luther
King said, “I have a dream….”. I have a dream also that this
vision of Root Cause Analysis is not only attainable, it will be
necessary to compete in the next decade. As the baby boomers
pass through the workplace there will be a shortage of skilled
workers to take their places and corporate memory will be lost
forever! Can we afford for this to happen?
