Yes, it is true that the jobs I mentioned were not of that degree of
criticality. The second one, the one where we went to parsing the text
version rather than the html version, was much closer to being critical,
though, because it deals with with informing hospoitals newly announced
information about defects and recalls of medical supplies, equipment,
and drugs. There are potentially high costs for errors, both in human
health and in legal liabilities. Yet we so far have to accept
hand-authored data that may vary in its format to some degree. However,
in this case we have humans in the loop, performing QC and editing
functions.
Naturally you have to be more strict when the task is critical in its
effects. Still, I recall, back when I used to make actual hardware -
not computer hardware, computers were hardly used in the factory then
if at all - our work required us to conform to some of the most
demanding quality control specs, and to impose them on our suppliers.
Nevertheless, as everyone who has been in a manufacturing environment
will agree, every so often a batch of parts or other material will not
meet specs. Then there has to be a meeting of knowledgable people to
decide what to do (the venerable Material Review Board).
And no matter how critical the mission, who can certify that a given
piece of software is bug-free? All you can do is to certify that it
passed certain tests and metrics, and was developed in a certain way.
Of course, these considerations are no argument for not applying good QC
or not worrying about bugs. But even in the best situations, things go
wrong or out of adjustment. Having a schema out of sync with the actual
documents is probably not uncommon, I would guess.
Cheers,
