Today's Compu-toon panel tried to poke fun at the non-sense instructions you can find when dealing with hi and low technical instruments. A friend of mine recently landed a project manager position at a highly visible utility company and his first project was to re-program the company's voice system...the program that tells you to push 1 for English or 2 for Spanish.
He indicated that not all scenarios that do come up in a conversation can and will be covered. It's just not logical. He went on to say there are misdirect information fed into these systems that later cause a problem
and they are very seldom corrected. So much for perfect instructions.
