Well, this is obviously wrong because it does not even mention the use of a BFH or vise-grips.

At my local bike collective, we recently figured out that if we want the fancy/delicate/expensive tools to stop breaking prematurely, maybe we should hide the BFHs.

It is obviously written by a mechanical engineer, who has no clue about computer engineering (my discipline). The difference between a hardware engineer and a software engineer is that the software engineer will kick things when they don't work, whereas a hardware engineer knows where to kick it.

Yeah, any engineering flow-chart that doesn't include the application of a hammer is fundamentally flawed.
