Largest junk mail printer in the world. Production plants in East Coast, West Coast, mid-country state. We had our own zip code at our plant. many many tractor trailers leaving and inserting our mail at various points in the postal stream. Which in turn meant following the rules perfectly. I learned about the ability to mail alligators and chickens in those days because I studied that god damn manual.
So anyway, it was just paying attention to the development from the early days on and occasionally visiting places.
While simultaneously doing our own OCR reader implementations on our own production lines.
When I wasn't in the middle of that database project or putting together a rack of sun servers my boss would go tell me to wander the floor and make it better. I was the guy with the clipboard and a very large budget and a boss who loved technology and gave me toys to play with.
