Why-why Analysis

Why-Why Analysis or which is also known as 5 Whys, is a very popular technique to identify root cause of a problem. ... By repeatedly asking the question “Why” (five is a good rule of thumb), we can peel away the layers of symptoms which can lead to the root cause of a problem

What comes to you when it finds a problem crunchy mind home leaked?

Surely you will soon replace it, correct no?

So what do you do if 1 or 2 weeks later Genting leaking again?

Surely you fix again properly go?

Thus if the problem recurs constantly repeated what you will replace the roof tiles hold?

• Definitely irritated?


• Certainly wasteful cost?


• Certainly wastes the time?


• Certainly wasteful energy?

Definitely moving house? LOH ... wrong just kidding ^^, peace

now ... Why do a definite improvement – definitely

Instructions to do problem solving, said his improvement from the Japanese hell we must ask why ... why ... why ... why ... why ... (maximum 5 x) or commonly called the Why-Why Analysis ?

To the above illustration let us analyze well with why-why analysis

Problems: Genting leaked every 2 weeks once.

The analysis :

Rev. 1: why Genting is leaking?
Answer: because there is a section of tile shifts and there are cracks also.

Rev. 2: why Genting eased and crack?
Answer: because there's a cat above the precarious

Rev. 3: why are there cats above Genting?
Answer: because there are leftovers in Genting

Rev. 4: why there are leftovers in Genting?
Answer: because there's a dump from the 2nd floor

Rev. 5: why people throw trash off the floor 2?
answer: because there is no trash on the floor 2

Solutions:

-Provide dumpster food is on the 2nd floor
-fixing a leaking/cracked Genting

it should be noted, that why-why analysis not forever be used 5 x, else why 2 x already found root cause/the root cause of the problem so STOP don't be dozen / forced use Rev up 5 x ... OK?
definitely confused? hopefully not.  .. ^^

let us imagine if these events befell within a machine factory, a technician who does not do a prior analysis of the damage to see the root of the problem/root cause, so There is a problem directly concluded (jump to conclusion) and it turns out his roots/root cause him not to be solved!

not imagine how much losses will be borne by the company?
machinery breakdown (time) = impacts to output, labor productivity, customer delivery, etc.
there's a who want to help count?

therefore it is important for companies to educate his employees butter
