How to draw seven red lines, all perpendicular, some with green ink, some with transparent ink, and one in the form of a kitten.
This is a caricature but experienced engineers do not behave like this. Users NEVER know with precision what they want and it is the job of the engineer put these wants into appropriate specs. When they say red the engineer must extract the Pantone scale range they want. Transparent does not mean invisible and the engineer must define the degree of transparency. Lines here clearly not straight lines and perpendicular means something different from the mathematical definition.
One of the most dramatic examples of the clash of cultures between managers and engineers is The Space Shuttle Challenger disaster when Space Shuttle Challenger (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members.
