Чтобы компания ответила на эти вопросы, надо обращаться в компанию, а не задавать их на форуме)) О контроле качества можете почитать вот эту статейку:
From Atomic Physics to Quality Management Там и узнаете про "вредителя из Ролекса"))
А касательно присутствия или отсутствия реакции вот как тот же Томас Брегель отвечал на прикольный случай с перепутанными 7-кой и 8-кой на циферблате:
Цитата:
Here's) a statement to the forum issue with the exchanged appliques on the 5001 dial.
It’s no discussion that such a fault should not occur.
The inspection of a dial has several steps:
1.At the supplier
a.Appliques are placed on the dial with small feet set into drilled holes
b.Final inspection of the suppliers quality control
c.Controle a la source by IWC inspection personnel at the supplier
2.At IWC
a.Dials are placed on the movement by final assembly
b.Watches are finally inspected by IWC QM Team
So we have at least 5 inspection steps during the production after setting of the dials.
The idea of one of the forum members that we are concentrating on the small issues and oversee the big ones is absolutely valid.
What does IWC do to avoid such cases?
1.We have instructed our personnel and placed the photo with the wrong appliques on the board of instructions in the inspection department.
2.I have personally presented the photo in the monthly department manager routine with 35 participants of all technical departments of IWC.
3.We have started since a long time a discussion with our suppliers to make a Poka Yoke solution which doesn’t allow to exchange the appliques by defining different hole distances for the small feet of the appliques. This last idea is not so easy to realize because it is expensive.
A defect like this can not be avoided to 100% as long as human inspectors are involved. It is a fact that visual inspections have an error rate of about 2%. When you have 3 inspections in a sequence you will have 0.02^3 = 0.000008. So about one of about 10000 might have this defect.
We are very thankful for the feedback of our forum member and would like to give to him a small gift. Could you please send to me the coordinates of him to me.
