When you speak to your "fellow" engineers and present them with "fact" i.e., measurements from an operating system, how do you make them realize that they did something incorrectly (wrong, half-assed)?
For example...you have a system which is very sensitive to analog interference and you shield the inputs outside of the industry (IEEE) standards and present analog data to the common of the A/D processor and now the floating ground (common) has a variable level (based on the input) AC signal when it is supposed to be 0V in reference...
How do I explain in a politically correct manner that what they are doing/did is ba-ba for the baby?
