Whether you spell it 5 Why, Five Why, 5 Y, or Five Y it is a quick and
easy way to find the root cause, solve the problem and develop effective
solutions.
Asking “Why” may
be a favorite thing with a 3-year-old child and it is certain to drive
you crazy after a while, but it could teach us a valuable lesson.
The 5 Whys is an
easy problem solving technique that helps you get to the root of the
problem quickly.
By repeatedly
asking the question “Why” (five is a good rule of thumb), you can peel
away the layers of symptoms which can lead to the root cause. Although
the method is called “5 Whys”, you may find that you will need to ask
the question fewer or more than the five times before you find the issue
related to the problem. The method may not lead you to the root cause
if exercised incorrectly.
I just wanted to thank Hal for the the great training sessions on
5Why, 8D and SPC over the last couple of weeks.
They were informative and very well facilitated.
Thanks Hal. Dave Hauter

Let’s examine
the different types of causes.
Symptoms:
Symptoms are not
causes. They are a manifestation of the cause. Developing solutions for
a symptom will not cure the problem. A fever accompanying a cold is a
symptom. Taking aspirin will help the fever but not cure the cold.
Direct:
Direct causes are in
fact causes but they are not the root cause. They are the immediate
reason why the problem occurred. Let’s suppose you go to start you car
and the engine won’t turn over. What might be a direct cause? A dead
battery could do that.
Contributing:
These causes
contribute to the direct cause but, again, they are not the root
cause. In the example of the car engine not turning over, what
contributed to the direct cause? Well, being the idiot I am I left the
headlights on.
Root Cause:
This cause is what we
are after. It is the most basic reason the problem developed. If
we can develop a solution or countermeasure for the root cause we can
cure the specific problem related to the root cause permanently. I'll
let you come up with your own fix for the leaving the headlights on.
Five-by-Five:
We
added a process we call the Five-by-Five Whys to help teams get and stay
on track. Whether you ask Why 5 times or 5 million times, if you get on
the wrong track you will still have the problem. Five-by-Five keeps you
going in the right direction.
If you would like
