I respectfully submit that such a tact may be easy to rally in smaller offices (which I'm getting the impression your type of office is, no dis meant), though small is such a relative term.
We have 250 +/- CADD Operators; probably a medium sized operation. The tactics you suggest are not practical when trying to corral this many cats.
Finally, relying on someone else to catch my errors, i.e. the QC guy, is not an efficient way to do things (scary actually, imagine if all of engineering did that
), it costs more to go back to fix something, but that's just my opinion, your mileage and experience may vary.
