And the second absolute of quality proposed by Philip Crosby is that the System of Quality is Prevention, 2
you achieve quality by prevention. In this course 3
we have talked about the cost of quality as well. In that we say that the cost of quality has three main components- 4
prevention, appraisal and failure. 5
But Crosby is in favor of is putting more investment on prevention not on appraisal. 6
Prevention is something whatever you do to make sure that the problems do not happen, you train people, 7
you have right tools and techniques. 8
You have right systems. 9
That's part of prevention, appraisal is testing, inspection. 10
So rather than emphasizing on inspection and testing put more emphasis on putting the systems the right 11
training people having the right to do that. 12
That's what this point emphasizes on is that the system of quality is prevention. 13
You achieve quality by prevention. 14
You invest well on prevention less on appraisal and failure costs. 15
And what he says was that when you look at prevention if you prevent something then error doesn't happen. 16
Error doesn't happen you really cannot miss that in the inspection. 17
So if the error is not there in the piece itself, you really cannot miss when you inspect that. 18
And just like many other gurus his emphasis is on processes. 19
Look at the processes rather than focusing on people focus on process. 20
And the secret of prevention is to look at the process and identify the opportunities for error where 21
things can go wrong. 22
Look at those processes, improve those processes, once you improve the processes. 23
Then there is less and less chance that the errors can happen. 24
So this was the second absolute of quality provided by Philip Crosby which is that the System of Quality 25
is Prevention.
