Like get the good doctor to set the protocols while some guy who has never been in an operating room just follows them.
Without getting bogged down in the details of the comparables, that article was noting that certain types of commercial kitchen tools are nonintuitive in how to kasher them.
So for example, he notes that the big soup thing can't be kashered. So the protocol is don't kasher it.
He notes that the fryer needs libun gamur. So you make a protocol on how to do libun gamur on deep fryers. A roofing torch? Ok. For how long? 10 seconds per spot? Ok. I can tell you that your expert is also not sitting there measuring temperatures, and can't "read" the temperature of steel by sight.
The dishwasher? Make a protocol.
How is this different than every other issue with hashgacha, that you have the experts making protocols for bug washing and bishul akum and whatever, and then the rank and file does it.
