I came up with a similar idea for a company several years ago where we had a team of people doing data entry from faxed documents. I wanted to build something that would do all the OCR it could and then display it to users to verify, which should have been a 10 times efficiency increase, not to mention speed and accuracy.

The idea was rejected, they wanted either a perfect solution or nothing. I don't know why, but for some reason the idea computers removing humans is acceptable to management, but computers augmenting humans wasn't.
