18.0 Root Cause Analysis
Root Cause Analysis is the method of problem solving that
identifies the root causes of failures or problems. A root cause is
the source of a problem and its resulting symptom, that once
removed, corrects or prevents an undesirable outcome from
recurring.

Symptom:The result or outcome of the problem.
An observation
§ We have late additions to the release that break the software
§ We have “core” defects that should been caught long before
production release
§ We make changes to software,stored procedures,or the
database only to discover it was a mistake.
§ We make promises to the customer before assessing the
impact on our resources or the technical difficulty
Problem:
§ Test coverage insufficient the detect latent bugs in software
§ We commit before understanding the consequences
Root Cause:
§ No software structure to determine test coverage or change
impacts on baseline.
§ No detailed understanding of our capacity for work and
productivity of our technical staff

18.1 Beyond the
Conventional
Wisdom of
Problem
Solving
Original Quote from George Bernard
Shaw
In Apollo Root Cause Analysis: Effective
Solutions to Everyday Problems,Every
Time, Dean L. Gano
The common approach to problem
solving is to categorize causes or
identify causal factors and look for
root causes within the categories.
Categorization schemes do not reveal
the cause and effect relationships
needed to find effective solutions.
It is the effective solution we are after.

Ignorance is a most wonderful thing.
It facilitates magic.
It allows the masses to be led.
It provides answers when there are none.
It allows happiness in the presence of
danger.
All this, while the pursuit of knowledge
can only destroy the illusion. It is any
wonder mankind chooses ignorance?
8. + The Persistent Problem …
Increasing use of larger and more complex systems
potentially results in greater number of problems,
evidenced by the symptoms of unstable software, latent
defects, unexpected performance issues.
Many of these problems and their symptoms, have a serious
impact on business operations than ever before. In many
case these problems are also more difficult to solve.

9. + … and the Persistent Unsuccessful
Solution to recurring problems.
In every human endeavor, a critical component to success is
the ability to solve problems.
Unfortunately, we often set ourselves up to fail with our
problem–solving strategies and our inherent prejudices.
We typically rely on what we believe to be common sense,
storytelling, and categorizing to resolve our problems.
Conventional wisdom has us believe that problem solving is
inherent to the subject at hand.

15. + The Five Whys
Five Whys involves holding meetings immediately – in our case the Friday
immediately following the release.
The problems can be anything – development mistakes, infrastructure
performance issues, process failures, or even internal missed schedules.
Any time something unexpected happens, we start the root cause analysis
with the 5Ways in the domain from the chart above.
Process – how do the process not catch the problem?
Tools – where in the path did the tool not catch the problem?
Training – what training was missing that created the problem?
Environment(s) – how did the environment fail to protect the baseline or
the production system?
Communications – what communications created the problem?
Management – how did management fail in its actions?
The 5 Whys NEVER seek blame. But are exclusively focused on
discovering the root cause that creates the problem, evidenced by the

18.2 Understanding
the Weakness
of our Current
Approach to
Root Cause
Analysis†
n A common Root Cause Analysis
approach is to start with a narrative of
what happened and how we think that
undesirable state was achieved.
n This is a storytelling approach.
Storytelling uses linear language and
linear thinking
n Stories start in the past, while causal
relationships start in the present
n Stories are linear while causal
relationships follow the branches of
an infinite set
n Stories use inference to communicate
meaning, while problems are known
by sensed causal relationships
The overriding theme of traditional
Root Cause Analysis is the focus on
the Root Cause. We can eliminate the
problem if we eliminate the Root
Cause.
This assumes the causal relationships
are linear and that problems come
from a single source.

Stories seldom identify causes because they are busy setting the stage for
who was where and when some action occurred.
A story is a sequence of events starting in the past, leading to the
consequences disguised as a root cause
Root Cause Analysis is Not about Story Telling
Performance–Based Project Management®, Copyright © Glen B. Alleman, 2002 ― 2016
861
21. + Core Failure of Story Telling and
the Filling Out of Forms
n Stories rely on experience and judgment of the authors to connect
the causes of the problem.The mapping between Event, Cause, and
Effect not provided in the story narrative.
n Story telling can be used to document the investigation and
describe the corrective actions. But stories are poor in providing the
analytical connections between cause and effect.
n Measures of the effectiveness of corrective actions can not be
provided by narratives.Traceability between Effect, Action, and
Condition can not be provided by the narrative.
n It is a false premise that analysis of a problem, its causes, effects,
and solutions can be reduced to filling out a form and checking
boxes.
18. Root Cause
Performance–Based Project Management®, Copyright © Glen B. Alleman, 2002 ― 2016
862
22. + Story Telling Is Not Good Root Cause
Analysis Approach
n Story telling describes an event by relating people (who), places
(where), and things (what) in a linear time frame (when).
n When using storytelling to analyze an event (system, outage for
example), the causes identified in the report are difficult to follow
and hinder our ability to understand the relationships between all
the causes and provide a critique of the analysis.
n The investigators may well understand all the causal relationships,
but because they are not presented causally it is difficult to know
these relationships.
n Peer reviews will result in more questions because of the missing
connections between Primary, Intermediate Effects, and their
Causes.

Performance–Based Project Management®, Copyright © Glen B. Alleman, 2002 ― 2016
863
23. + Problem with the Story Telling Approach
to Root Cause Analysis
n Stories start with the past – we saw this happen and something else
happened after that,and then something else happened…
n Causal relationships leading to the Root Cause start with the present
and work backwards to the causes – both Activities and Conditions of
this cause.
n Stories are linear – they come from the minds of the story tellers,
usually as a linear time line.
n The linear understanding of an event in a time sequence from past to
present, ignores the cause–and–effect principle.
n Since we do not understand the branched causes, we use our own
understanding of cause rather than the actual causal connections.
n Stories use inference to communicate causes.
n Causal relationships require clear evidence of the existence of each
cause and its connection to the effects.

Performance–Based Project Management®, Copyright © Glen B. Alleman, 2002 ― 2016

24. + Root Cause Analysis is the
Event, the Cause, and the Resulting Effect
n We need a structured approach to investigating and analyzing
significant adverse events or system deficiencies and their required
improvement – not based on Story Telling.
n We need an approach that provides information and tools to be
incorporated into risk management, quality management,
independent verification and validation and improvement
procedures in order to:
n PREVENT future occurrence of adverse events that cause or can cause
undesired performance of our systems.
n CORRECT practices that have led to identified deficiencies.
n This approach separates story telling from the Primary Effect, and
the cause–effect chain leading to the Primary Effect.

25. + A Better Approach to Root Cause Analysis for
Primary Effect, Cause, and Effect
n Direct causes often result from another set of causes – the
intermediate causes – and these may be the result of still other
causes.
n This chain of cause and effect needs to be revealed in a way that
clearly points to the corrective actions.
n When a chain of cause and their effects is followed from a known
end–state (time now), back to an origin or starting point, root causes
are revealed and corrective actions can be applied.
n A root cause is an initiating cause of the causal chain which leads to
an outcome or effect of interest.

n Categorical thinking creates the believe that once categorized, we

n No causal chain from Primary Effect to related Cause and Effect
n No Actions and Conditions to connect to the Effect
n Under what conditions was the Effect observed?
n What actions triggered the Effect?
n No evidence for each Action and Condition
n Stopping too soon, before actual Root Cause found
Every Effect is caused by momentary Action coming
together with existing Condition in the same time
and space.

n Is this really what the customer wanted me to do?
n Did I consider the impact of my actions?
n If I don’t have time to be careful,then what damage will result from my
actions?
n Did I consult with someone who knows more than I do about what the
solution should look like?
n Am I being as careful as I should be,when I make a change?
n Am I being pressured to do something I know isn’t the right thing to do?

Development
n Do just enough Root Cause Analysis
sessions
n Have a knowledgeable facilitator
n Communicate the corrective actions
n Do Agile Root Cause Analysis
Root Cause Analysis is used in
software development to build a
shared understanding of a problem
to determine the first or “root”
causes.
Knowing these causes identifies
effective improvement actions to
prevent similar problems in the
future.
Root Cause Analysis in Agile stops
problems that have been inhibiting
the team for too long.

Analysis
n Events have two contributors ‒ the condition and the action. Both must be found
before root cause can be determined for the primary effect.
n There is an endless chain of cause and effect, stopping too early is a common
failure mode of Root Cause Analysis
n Formal Root Cause Analysis processes and tools provide information not
available with the narrative approach
n Without determining the Root Cause and suggested solution just address the
symptoms.This approach does not remove the cause and allows the symptoms
to recur in a loop of fix, break, fix.
