Desire
Document the “gap” that needs addressed with this project
A PROBLEM IS DEFINED AS A DEVIATION BETWEEN WHAT SHOULD BE HAPPENING,
AND WHAT IS ACTUALLY HAPPENING.
Identify what the problem is before beginning analysis
Ideal state / target
Gap = Problem (abnormality)
Current condition
Outputs:
Theme, Problem and gap defined and approved
Customers acknowledged and input documented
Type of problem (lean or variation/quality)
Note: Be careful about listing
symptoms instead of the problem
and be careful to not assume a
cause of the problem

Identify: ASK, How this project ties to the company goals?
The gap that is initiating the project could come from:
Quality - Customer complaints
Cost - Budget targets not met
Productivity - Some desired improved level
Other – Safety, Environmental, etc

Set the priorities and targets for the team by
establishing the project and/or problem
statement and goals or targets for improvement.
3.
Set Priorities
& Targets
Use the historical data to categorize the project into smaller, more concrete problems.
If working on a big project , then tackle the most impacting problem 1st, then the 2nd most important, until
the big project target is met.
One Specific Problem Statement:
Document the problem statement or statements (if
addressing more than one defect or object)
One object
One defect
Target: Document the target for
improvement such as 50% reduction
and note the ultimate goal.
2. Break Down The Problem
5
3. Set A Target
- Make the commitment.
- Measurable, concrete and challenging.
> Do what by how much by when?
> Clarify rationale and impact.
> Output oriented (things to be achieved, not things to do).
- Use data to categorize the problem
into smaller, more concrete
problems. Use division points
such as Who, What, When
or Where?
- Narrow the focus to one aspect
of the problem to solve.
- Genchi Genbutsu: Go & see the
smaller problem and visualize
the process.
(Contain the problem if needed)
- Specify the point of cause and
state the problem to engage.
- Keep in mind scope.

5.e
Study Actual
Facts
Compare your process to others to understand your current situation and learn from it.
By comparing your process to other processes, you can learn a lot about how to develop
and improve yours.
Benchmarking can show you:
Where your weaknesses are
Which areas you can improve
New or different ways to do things
Strategies for improvement
What is possible
Where your strengths are and how to
maintain them
Where you can increase efficiency
Hints:
Look at other AGC sites even in other
parts of the world
Is there another company that is known
for this process
Note that Benchmarking can be used in
step 1 also to help establish the “gap”

occurred
To create possible cause statements for
testing against the facts
List Possible cause statements from Differences and
Changes along with the Fishbone Analysis.
Purpose:
How could…
a change
a change and a difference
a change and another change
a difference alone
…cause the problem?
What causes can be generated from Fishbone
Analysis
Write a short statement in object/defeat format
Explain how the cause creates the problem
Examples
Possible Cause Statement:
I ran over a piece of metal in the road 2 weeks
ago which may have punctured my
radiator.
The drain valve is partially open causing it to
leak.
The automatic transmission connection line
has worked loose causing a leak.
A hose has developed a hole allowing a leak.

Test Possible Causes against the Is/Is not specification.
Eliminate some of the causes and list assumptions.
6.c
Analyze
Facts
Evaluating possible causes against the
IS/IS NOT specification
• To save time by eliminating possible
causes that do not make sense
Ask:
If Possible Cause is the cause of Problem
Statement, how does it explain both the IS
and the IS NOT?
• Ask about each pair of IS/IS NOT data
• Eliminate any cause that fails
• List all assumptions
Examples
* I ran over a piece of metal in the road 2
weeks ago which may have punctured my
radiator.
Explains only if started leaking 2 wks ago
* The drain valve is partially open causing it
to leak.
Explains only if started leaking 2 wks ago
* The automatic transmission connection
line has worked loose causing a leak.
X Does not explain – You would see
transmission fluid not coolant
* A hose has developed a hole allowing a
leak.
Explains only if started leaking 2 wks ago

Prioritize the Possible Causes by reviewing the
assumptions and picking the most likely.
6.d
Analyze
Facts
Explanation
• Identifying the cause that is most
reasonable
• To pick the possible cause to verify first
Ask:
• Which of the possible causes is the most
believable?
• Most Probable Cause has:
Reasonable assumptions
Fewest assumptions
Overall simplest assumptions
Example
All of the causes have potential in this
case but the ones that are most likely are?
1. Puncture to the radiator
2. Puncture to the hose
Global Quality Management Solutions Phone: 1-888-216-8324
21. Global Quality Management Solutions, LLC
Verify the most likely Possible Cause(s) by 3e observation,
research/testing and turning the defect/issue on/off.
Proving the cause of the defect
To identify steps to take, use:
• Observation - How can we look at the cause?
(3e)
• Research - How can we experiment to test this
cause? You want to be able to turn the defect
on and off
• Results - How can we try our Fix to see if it
works?
Example
Observation in this case, go and look

Root Cause
Example (not complete)
Deduction: Why-Why or 5-Why Analysis
A way to find the actual Root Causes.
To make sure we countermeasure the correct
items.
The purpose of Root Cause analysis is to go
beyond direct and somewhat apparent causes
and figure out the underlying reasons for the
event.
It is not enough to just find what broke or
changed and fix it. We must go to the next
level and determine the root cause if we want
to minimize repeat problems and eliminate this
issue in the future. Outputs:
Root cause(s) identified and testedGlobal Quality Management Solutions Phone: 1-888-216-8324
23. Global Quality Management Solutions, LLC
Verify the root cause(s) by testing and documenting
the results preferably recreating the issue/defect.
7.b
5 why
Root Cause
The purpose of Root Cause verification is to test the hypothesis. Once the
issue or defect has been recreated, then at least one root cause has been
confirmed.
Verify the root cause(s) by trial and error or
Design of Experiment
Recreate the issue/defect
Use a summary table to show the result of the
testing.
Hints:
For more than one variable, use
a table like the one below
Verify the recreated defect is
exactly the same, not
similar.

a thesis (idea for
improvement), Conduct

• If SGA team, then copy with summary sheet to CI Rep at your site
• Share with others who need the information.
• Make sure management is aware of situation.
• Give copy to your QA department if it is quality related.
• Keep a copy on file. This could be useful in the
event of a similar problem.
