DEFINE THE
PROBLEM
STRUCTURE
THE ANALYSIS
FIND THE
SOLUTION
Our problem solving approach begins by answering a simple series
of questions
• Is there a problem or opportunity?
• If so where does it lie?
• Why does it exist?
• What could we do about it?
• What should we do about it?

ROOT CAUSE

How to find a good hypothesis
Think outside the Box:
Start by Asking Questions:
• Talk to lots of people about the core problem
• Brainstorming during case team meeting
• Ask “5 Why’s”
Validate Your Initial Hypothesis:
• Assume perfect rationality — how should the business system behave?
• Look for analogies (other industries or problems)
• Imagine that you had perfect information — what would the ideal analysis look like?
• Think about the problem from a different angle
• Talk to people who think differently

Step 3:
Brainstorm
In the team:
– Brainstorm a list of sub-causes (follow the rules of brainstorming)
– Add the sub-causes to the fishbone diagram, using post-it notes

Step 5:
Identify most likely causes
In the team:
– Analyze the data and information gathered
– Through open discussion, clarify and identify most likely causes
– Challenge each other’s ideas as necessary
– Rank most probable root causes through voting (each person ranks
each probable cause on a 1-5 basis, where 1 is lowest, and 5,
highest probability) [See left-hand graphic.]
– Circle the top vote-getters on the fishbone diagram as probable root
causes [See right-hand graphic.]

Helpful hints
Do Root Cause Analysis with a team of
people who are owners or stakeholders
in the process (who will see the
benefits of solving the problem)
Follow brainstorming rules when
generating initial ideas:
– Generate as many ideas as possible and list
them under main headings as possible
causes
– Do not allow criticism of any idea initially (no
idea is a bad idea)
– Build on the ideas of others
Avoid working the solution of any
cause early in the process
Don’t be hindered by excessive neatness
during the construction of the diagram.
Ideas must flow freely
Verify root causes through data
gathering and testing
Rewrite or restate the problem statement
if the group is derailing and needs to
refocus
Identify the criteria against which you will
evaluate the final solutions in advance
Challenge the solution
Agree, in advance, how you will measure
the effectiveness of the solution in the
pilot
