I agree that it's not a perfect analogy, and perhaps shouldn't be taken as an analogy at all. That said, I don't think that means there's nothing to be learned

I agree that it's not a perfect analogy, and perhaps shouldn't be taken as an analogy at all. That said, I don't think that means there's nothing to be learned from what did and didn't work. It's rather similar to how I like to reference Demming's 14 points in term of how to manage any business: obviously not all apply, but many do, and you can still learn valuable philosophy from the ones that don't.
