quality checks are designer defined.
If quality checks are tinkered with then the cost of poor quality kicks in.
A missile system is not to be checked based on experience.
The designers and the manufacturing engineers are the ones who decide on which quality checks to keep and which to waive off based on experience.
For something like a missile, there would be thousands of drawing requirements. If all of them are to be checked for quality, it would take more time to check than to make it. The designers need to prioritize.
This is not a matter subject to opinion or expediency.
There are set principles involved here. A lot of these PSUs, as well as the private players, are subject to the requirements of standards like AS9100D + DO160G derived test specs apart from many others that apply simultaneously. Apart from all this, the customer is free to impose any other test/inspection requirements that he may choose and the supplier has no choice in the matter, except to comply and may be charge extra for the test.
The question of "waiving off" ANY inspection checks based on "experience" simply does not arise.
whose experience is relevant, and who is to judge whose experience is right and somebody else's experience is wrong
The inspections and the control plans are objective and not subjective.
Aviation standards are 100% inspection of each and every component. Sampling is not the norm here and nor is it allowed or permitted.
customers are not going to be bullied or bludgeoned into submission by some silly know it all who says that "in HIS opinion, checks are not required and they are a waste of time" Such companies or organisations will die a very quick, painful and an extremely well deserved death.
Yes indeed, there are tens of thousands of drawings. Why would there not be because such is the nature of the beast.
Pay close attention to each and every one of them or if you don't want to, then get out of the business.
Even flipping burgers these days are subject to numerous quality checks and stringent stage inspections.
Hamburger University is a 130,000-square-foot (12,000 m2) training facility of McDonald's, located in Chicago, Illinois. This 80 acre facility and corporate university was designed to instruct personnel employed by McDonald's in the various aspects of restaurant management.
Key characteristics of the burgers and their other food offerings are extremely minutely and stringently controlled and not to mention, enforced world wide.
Why can't the same be done for missiles and their parts here. Or our own chalta hai university takes precedence over all else, even to the extent of jeopardizing national security.
The vital question of whose father what goes when the missile does not perform as advertised is not being asked when it should be the very first question in everyone's mind.
Have we reached the stage of contemptuously overriding even CAG reports that are presented to parliament by saying that some joker on the shop floor is the final be all and end all of our defence systems.
how many corners are we going to cut
BTW, manufacturing engineers deciding on quality checks is like the fox guarding the henhouse. This is not done anywhere in the world.
I am not saying this, any, even halfway decent book on manufacturing will bear me out.
In the many hardworking PSUs that are there, no one, but no one ever talks like this about taking shortcuts in quality and inspections.
Inspection and quality shortcuts as part of the management or design narrative are sure fire career killers. No customer will ever deal with such organisations.
