. . . . I had to deal with outsourced services to India, back around the turn of the century, when I was working for a Dot-com. We were experimenting with outsourcing. The boss had contracted some Indian services firm to take 1000 Material Safety Data Sheets, in scanned PDFs, and type the contents of each into a Microsoft Word file. As I recall, he paid 500 bucks for it.
Average results were 20+ errors per page. Spelling, words missing, whatever, it was there in the results file.
This compares to a similar contract, same task, somewhere in Flyover Country. Zero errors, and notes pointing out mis-spellings in the ORIGINAL PDFs. Cost 5 grand, but worth it. . . .
