I’m 2 months now in my first work and my boss wants me to research about corrective actions. And I really need a lot of help and informations.
Anyway, can someone tell me what does “5 whys / 2 hows” exactly mean? Where and when do we apply it? How do we apply it? Is there any special technique/method for this?
I truly appreciate your warm and kind response.
Thanks in advance!
Regards,

Marc RichardsonParticipant@Marc-RichardsonInclude @Marc-Richardson in your post and this person will
be notified via email.The 5 why’s typically refers to the practice of asking why the failure has occurred five times in order to get to the root cause of the problem. No special technique is required. An example is in order:
You are on your way home from work and your car stops:
-Why did your car stop? Because it ran out of gas.
-Why did it run out of gas? Because I didn’t buy any gas on my way to work.
-Why didn’t you buy any gas this morning? Because I didn’t have any money.
-Why didn’t you have any money? Because I lost it all last night in a poker game.
I hope you don’t mind the silly example but it should illustrate the importance of digging down beneath the most proximate cause of the problem. Failure to determine the root cause assures that you will be treating the symptoms of the problem instead of its cause, in which case, the disease will return, that is, you will continue to have the same problems over and over again.
Also note that the actual numbers of why’s is not important as long as you get to the root cause. One might well ask why did you loose all your money in the poker game last night?

(How have you been, anyway? Great news for Kay, huh?)
I would add that the original poster may be mixing the “5 Why’s” with the “5W’s/2H’s” tool for initial defect analysis:
Who
What
When
Where
Why
How
How Much/Often

You know – the Mark Richardson we know denies all knowledge of “iSix Sigma” so it leads me to suspect that there are 2 Mark Richardson’s out there that are also Senior QA people – scary if its true Hu – work out the probability of that happening.
5 Whys – great tool – just be cautious of going down the wrong track – get data to support your why’s.

Marc RichardsonParticipant@Marc-RichardsonInclude @Marc-Richardson in your post and this person will
be notified via email.To set the record straight, my name is Marc with a c, not with a k, and I do not deny all knowledge of the existence of isixsigma, plainly, I couldn’t post here if I didn’t know about. For what it’s worth, I have recommended this sight to quite a few people.

Marc RicharsdonParticipant@Marc-RicharsdonInclude @Marc-Richarsdon in your post and this person will
be notified via email.OK. I see what happened. You know someone named Mark (with a k) Richardson and mistook me for him. No harm done. I’m just glad we got it straightened out.
Kelly, looks like youre right about the 5 W’s/2 H’s. You looked at it and saw one thing, I looked at it and saw another. In the end, we all benefit.
Thank You,
