ROOT CAUSE ANALYSIS PowerPoint Presentation

INTRODUCTION
Root cause analysis is simply a tool designed to help
incident investigators describe WHAT happened
during a particular incident, to determine HOW it
happened, and to understand WHY it happened.
Only when investigators are able to determine WHY
a failure occurred will they be able to specify
workable preventive measures.

Define Root Cause Analysis?
Root cause analysis involves a range of tools,
approaches, and techniques used to uncover the
primary causes of problems.
The goal of RCA is to prevent recurring issues from
happening by eliminating their root causes. The
process follows a chain of causes and effects to
pinpoint the origin.

Toyota founder Sakichi Toyoda originally developed
Root cause analysis to improve the efficiency of the auto
making manufacturing process.
RCA is a critical component of the international Total
Quality Management (TQM) movement, the corporate
process improvement movement, and the drive
for quality control.

What is root cause analysis?
• A standard process of:
1. identifying a problem
2. containing and analyzing the problem
3. defining the root cause
4. defining and implementing the actions required
to eliminate the root cause
5. validating that the corrective action prevented
recurrence of problem

Benefits
By eliminating the root cause…
You save time and money!
• Problems are not repeated
– Reduce rework, retest, re-inspect, poor quality costs, etc…
• Problems are prevented in other areas
• Communication improves between groups and
• Process cycle times improve (no rework loops)
• Secure long term company performance and profits

Definition and purpose
Definition: Although there is substantial debate concerning the definition of a root
cause, as defined in this system:
A root cause is the most basic cause that can reasonably be identified and that management
has control to fix.
This definition contains three key elements:
1. Basic Cause
2. Reasonably Identified
3. Control to fix
1) Basic Cause
The goal of the investigator should be to identify basic causes. The more specific we can be
about the reasons why an incident occurred, the easier it is to arrive at
recommendations that will prevent recurrence of the events leading up to the incident.
2) Reasonably Identified
Incident investigations must be completed in a reasonable time frame. It is not practical to
keep valuable manpower occupied indefinitely searching for the causes of incidents.
Root cause analysis, to be effective, must help investigators to get the most out of the
time that they have allotted for the investigation.

3) Control to Fix:
Investigators should avoid using general cause classifications such as
"operator error." Such causes are not specific enough to allow those in
charge to rectify the situation. Management needs to know exactly why
a failure occurred before action can be taken to prevent recurrence. If
the investigators arrive at vague recommendations such as "Remind
operator to be alert at all times," then they have probably not found a
basic enough cause and need to expend more effort in the investigation
process.

Purpose of RCA
The purpose of Root Cause Analysis (RCA) is to
systematically identify and address the
underlying causes of problems or issues, rather
than merely treating their symptoms.
The primary objectives and purposes of RCA
include:
1. Preventing Recurrence: Identifying and
eliminating the root causes of problems helps
prevent the recurrence of similar issues in the
future. This leads to long-term solutions rather
than short-term fixes.

• A symptom is a sign or
indication of a root cause,
but it is not, by itself, a
cause.
• Most often, symptoms lack
specificity and are difficult
to categorize.
• It is very difficult to develop
solutions to directly address
a symptom.
Root causes
• A root cause is the real
reason for a business or
performance problem.

Fishbone Diagram
(Ishikawa or Cause-and-Effect Diagram)
It is also known as Ishikawa diagram or Cause-and-Effect diagram, is a visual
representation used to analyze and identify the possible causes of a specific
problem or effect.
A fishbone diagram is a visualization tool for categorizing the potential causes of
a problem. This tool is used in order to identify a problem’s root causes. Typically
used for root cause analysis.
It was developed by Dr. Kaoru Ishikawa, a Japanese quality control expert. The
diagram takes its name from its appearance, which resembles the skeleton of a
fish.

Use of fishbone diagram
A few reasons a team might want to consider
using a fishbone diagram are:
 To identify the possible causes of a problem.
 To help develop a product that addresses issues
within current market offerings.
 To reveal bottlenecks or areas of weakness in a
business process.
 To avoid reoccurring issues or employee burnout.
 To ensure that any corrective actions put into place
will resolve the issue.

5 Whys
The "5 Whys" is a technique used in Root Cause
Analysis (RCA) to identify the underlying causes of a
problem by asking "why" multiple times.
Here's an example:
Problem 1: Production line downtime
1. Why did the production line stop?
Because the machine malfunctioned.
2. Why did the machine malfunction?
Because a critical component failed.

5 Whys
3. Why did the critical component fail?
Because it was not properly maintained.
4. Why was the component not properly maintained?
-Because the maintenance schedule was not followed.
5. Why was the maintenance schedule not followed?
Because there was a lack of communication and
coordination between the maintenance team and
production scheduling.

5 Whys
Problem 2: Production line downtime
1. Why did the production line stop?
Answer: The machine overheated.
2. Why did the machine overheat?
Answer: The cooling system failed.
3. Why did the cooling system fail?
Answer: The pump stopped working.
4. Why did the pump stop working?
Answer: It was not receiving regular maintenance.
5. Why was the pump not receiving regular maintenance?
Answer: There was no scheduled maintenance plan in place.

5 Whys
Problem: Production output is consistently below target.
Why is the production output below target?
Because the machines are frequently breaking down.
Why are the machines frequently breaking down?
Because regular maintenance is not being performed.
Why is regular maintenance not being performed?
Because there is a shortage of maintenance staff.
Why is there a shortage of maintenance staff?
Because the company didn't hire additional staff to keep up with
increased production demands.
Why didn't the company hire additional staff to keep up with
increased production demands?
Because there was a budget constraint, and hiring was frozen.

5 Whys
It's important to note that the number
of "whys" may vary based on the
complexity of the issue. The
objective is to continue asking "why"
until a clear and actionable root
cause is identified, enabling effective
problem resolution.

Scatter Diagrams
A scatter diagram, also known as a scatter plot or scatter graph, is a visual
representation of the relationship between two variables. It is commonly used
in statistics and data analysis to examine the correlation or association
between two quantitative variables. The data points are plotted on a Cartesian
plane, where each point represents a unique combination of values for the
two variables.
Here are the key components and characteristics of a scatter diagram:
1. Horizontal Axis (X-Axis)
2. Vertical Axis (Y-Axis)
3. Data Points
4. Trend Line
Scatter diagrams are commonly used in various fields, including
statistics, engineering, economics, and the sciences, to gain
insights into the relationships between variables and to inform
further analysis or decision-making.

Pareto Analysis
Pareto Analysis, named after the Italian economist Vilfredo Pareto, is a decision-making
technique that prioritizes and focuses on the most significant factors contributing to a
particular problem or situation. It is based on the principle known as the "80/20 rule,"
which states that approximately 80% of effects come from 20% of causes.
The main steps in conducting Pareto Analysis are as follows:
1. Identify the Problem or Issues
2. Collect Data
3. Categorize the Data
4. Calculate the Frequency of Each Category
5. Calculate Cumulative Frequency
6. Create a Pareto Chart
7. Identify the Vital Few
8. Focus on Improvement
Pareto Analysis is a valuable tool in prioritizing efforts and resources to address the
most significant issues. It is widely used in quality management, project
management, and problem-solving across various industries.

Control Charts
A Control Chart, also known as a Shewhart chart or process-behavior chart, is a
statistical tool used in Root Cause Analysis (RCA) to monitor and control processes
over time. It is particularly valuable for identifying variations or changes in a
process and determining whether these variations are within acceptable limits.
Control Charts help distinguish between common cause variation (inherent to the
process) and special cause variation (due to external factors or specific events).
Here are the key components and concepts associated with Control Charts in the context
of Root Cause Analysis:
1. Process Data:
2. Data Subgroups
3. Control Limits
4. Central Line
5. Data Points on the Chart
6. Pattern Recognition
Control Charts are widely used in industries such as manufacturing,
healthcare, and quality control, where maintaining consistent and
predictable processes is crucial for operational excellence.

Fault Tree Analysis (FTA)
Definition: Fault tree analysis (FTA) is a systematic approach that identifies the primary causes of
operational and maintenance (O&M) issues. It’s a deductive analysis tool that begins with a general
conclusion before working backward to identify potential causes. Maintenance leaders complete
this problem-solving exercise using visual representations of cause and effect known as fault tree
diagrams.
USED: Fault Tree Analysis (FTA) is a systematic and graphical method used in Root Cause Analysis (RCA)
to identify the root causes of a specific event or failure. It is particularly effective in industries
where safety and reliability are critical, such as nuclear power, aviation, chemical manufacturing,
and aerospace. FTA is used to analyze complex systems and understand how various events or
failures contribute to a specific undesired outcome.
The key elements and steps involved in fault tree analysis:
1. Top Event
2. Intermediate Events
3. Basic Events
4. Logic Gates
5. Analysis
6. Root Causes

Fault Tree Analysis offers several benefits in RCA:

5 Whys technique
The 5 Whys is a problem-solving technique that involves asking "why"
repeatedly to identify the root cause of a problem or issue. It is a
simple and effective method for digging deeper into the underlying
factors contributing to a problem. The goal is to ask "why" five times
(or more) until the true root cause is identified, enabling organizations
to address issues at their source rather than treating symptoms.
There's a few step to using the 5 whys technique:
Identify the Problem:
Clearly define the problem or the undesired outcome you want to address.
Ask "Why" for the First Time:
Start by asking why the problem occurred. This is the first level of inquiry.
Example: "Why did the production output decrease?"

5 Whys technique
Repeat the Question for Each Answer:
For each answer given in response to the previous "why," ask "why" again to probe deeper
into the causes.
Example:
• Answer 1: "The machines broke down."
• Second "Why": "Why did the machines break down?"
Continue Asking "Why":
Repeat the process, asking "why" for each subsequent answer, until you reach the fifth level
or until a clear and actionable root cause is identified.
Example:
• Answer 2: "There was a lack of preventive maintenance."
• Third "Why": "Why was there a lack of preventive maintenance?"

5 Whys technique
Identify the Root Cause:
Continue asking "why" until you reach a point where the answer is a fundamental issue
that, when addressed, can prevent the recurrence of the problem.
Example:
• Answer 3: "There was a shortage of maintenance staff."
• Fourth "Why": "Why was there a shortage of maintenance staff?"
• Answer 4: "The company implemented a hiring freeze due to budget constraints."
In this example,
The fifth "why" revealed the root cause – a budget constraint leading
to a hiring freeze, resulting in a shortage of maintenance staff and
ultimately causing a decrease in production output.

Failure Mode and Effects Analysis
