1. Root Cause Analysis

2. What is RCA?
Root Cause Analysis is a structured step-by-step
technique that drills on any problem to extract its real
cause. It is a widely employed technique in corporate
houses to find the exact cause of any loophole in their
process.
• It ascertain and analyze the causes of problems
and chart out solutions to prevent problems from
further occurrence.
• It is a process to help stakeholders to
understand the causes of a problem well enough
to achieve permanent solution of that problem.

3. THE PROCESS
A root cause is one of the
most basic, or many causes
underlying a redundant
problem.
Basically, RCA involve the following steps:
• What Happened?
• Why it happened?
• What it can be done to prevent re-occurrence of the problem?
RCA attempts to treat the real
cause/causes of a problem, rather
than just dealing with the symptoms
of a problem.

a sample 5 why template.
One of the most employed problem – solving technique in RCA to
find the main cause of any problem. The technique focused on the
cause – effect relationship in case of a problem or a process failure.
In the below example, you will discover how 5 why can be used in
detecting the root cause of a problem:

5. Benefits of RCA
RCA helps in process improvements for
organizations, chart out lasting improvements
and most importantly, create a roadmap to follow
for thorough understandings of relationships,
causes and effect and solutions.
By practicing RCA, you eliminate taking actions
on redundant symptoms, and help you to work
on actual root cause of problem thus bringing
lasting solutions to an organization.
You establish solid step-by-step procedure with
process mapping for your process that improves
your overall organizational efficiency.

6. Limitations of RCA
RCA presupposes a single source of the
problem. The model assume linearity and the
existence of cause and effect relationship for
problem solving. However, in the real corporate
world – things are not as simple and
straightforward. Business processes are
complex systems involving people, process and
technology. Correspondingly, many problems
are non-linear involving many known and
unknown components. In such scenarios, other
business problem solving tools need to be
considered.
