Actually what we name quality assurance tools (i.e. Osmose, OSMI and
similar) is fairly similar to techniques used in industrial production
processes as part of quality assurance and quality management
endeavours - with the same advantages and limitations.
Like in those cases the term quality assurance is somewhat misleading
since watching over process parameters and performing automated checks
on its own does not in any way assure a certain level of quality. But
detecting and quantifying quality problems is of course the first step
towards assuring a certain quality level.
And measuring production quantity is usually not part of a quality
assurance process - unless it is part of a yield or efficiency
measurement, i.e. relative quantity.
Of course most of the quality assurance tools we have at the moment only
measure plausibility and internal consistency of the data. We have
only very few automated QA tools that use any kind of outside reference
to gauge accuracy of the data.
