    This is fair, I’d rather be re-reading the original text.

    Before “five whys” was coined, it was just a section in Taiichi Ohno’s Toyota Production System, and a pretty good one (https://books.google.com/books?id=7_-67SshOy8C&lpg=PP1&dq=toyota%20production%20system&pg=PA17#v=onepage&q&f=false).

    Alas, but, making these few paragraphs into a practice, and then making that practice into a marketable trend, has indeed gotten us away from what Taiichi Ohno was trying to get people to do.
