We can classify the cost of quality into three broad categories. 2
One is the Prevention. 3
Whatever cost we are occuring to prevent things from going wrong. 4
That's a prevention cost. 5
The next will be Appraisal, appraisal is the cost of maintaining the quality by upraising by checking 6
by inspecting. 7
And the third the cost of quality is Failure if everything fails then there is a cost related to the 8
failure that becomes the failure cost of quality. In failure 9
also there are two aspects whether that failure has occurred Internally or Externally. 10
So if that has occurred internally what you do then in that case would be you will repair reject or whatever 11
you do. 12
But if that happens externally, externally in the hands of the customer then there are costs related 13
to that. 14
We will be looking at these let's say four categories- Prevention, Appraisal, Internal Failure and External 15
failure 16
in next four slides and understand what these costs constitute of. What is included in prevention cost, 17
what is included in the appraisal cost of quality, what is included in internal failure and external failure cost 18
of quality. 19
Let's see that on the next four slides.
