The problem I have is that when I'm asked to follow a procedure that you know just while reading it was created by someone with less experience and better/faster/cheaper ways are available to get to the same result. Deviation will however get you into trouble because the procedure is what is vetted and approved. Deviations from procedure could open one up to liability if things later do not work as expected.
While we can automate away most things, human learning doesn't seem to be one of them.
A teacher should therefore embrace the fuzzy nature of explaining concepts.
