I suggest quality is compliance with requirements. If I wanted some wood screws then if I was prepared to accept a fairly high failure rate because of slot failure and would never want to remove them and at a cheap as chips then things that exceeded my technical requirements but cost considerably more would be low quality because they did not meet all of my requirements.
Same with a fishing reel. If I wanted a thing that helped torture fish (I loath so called sport fishing) and was quite prepared to update every year or so then the Chinese product at a cost much less than something that would run smooth as silk and last for years would be higher quality.
The gotcha arises when the manufacturer of the reel sells it at a price for which the buyer expects the same spec and mission life he expected at which point it becomes lower quality
Hence my claim that "quality" is subjective depending as it does on how it meets requirements.
The chinese reels don't have the tolerances or build quality of the American ones (which incidentally, in my case are over 20 years old). I can't chuck 5oz - 6oz on a Mark II or III anywhere near I can on my old Mark 1's. I know a lot of Mark II and III's sent back to suppliers because of manufacturing defects and the ones I have are ready for the bin as they don't withstand the harsh environment of sea fishing.
So, back to quality.
There a many aspects to quality and you need all of them to design, develop, manufacture, sell, support and maintain a product. On one hand, quality is subjective by the average consumer because they have their own expectation (usually based on value for money) but for regulators, quality managers, compliance consultants etc, quality is more of a measure of how closely a product has followed the manufacturers approved quality management system. That quality management system (including procedures for generating requirements, deriving a products design, tests to demonstrate repeatability, reliablity and predictability etc etc) must be inclusive of all regulatory requirements and incorporate best practise across the board. Training and audits allow for the quality environment to be assessed and improvements, corrections made from there, but in general "Quality" is really more to do with business performance that delivers robust products than a personal opinion on whether something is crap or not. This is why it is best practise to audit a potential manufacturer to assess their quality management systems before allowing them to make anything for you.
Thats basically it in a nut-shell (form someone who is a lead auditor, regulatory compliance consultant, pharmaceutical and medical device quality manager, IT project manager, business analysts and an ex-software engineer blah blah blah).
Sorry for the long winded response ....
