THE BLUEPRINT FOR SUCCESS?

In my past as a technical illustrator, I recall an Army repair wagon we were drawing from their blueprints… I noticed how high the center of balance was and spoke up saying it looks like it might tip over if it goes over 35 mile an hour… Of course they built the thing as per their specs – and it promptly tipped over after 35 miles per hour. Anyway, my point is – even blueprints need to be correct or else things don’t work.
