The BOM Rap
Why bother with a yawn-inducing topic like bills of materials (BOMs)? Bring it up with manufacturing professionals and their eyes glaze over instantly. And the Lean literature is mute on the subject. I even asked Michael Ballé for his input on the subject and he responded that he had none to offer.
Yet everyone involved with assembly agrees that BOMs are at the core of their activity, that BOMs have chronic accuracy issues, that the workarounds to these inaccuracies impair the companies’ ability to update and customize products, and that BOM maintenance hogs resources. Perhaps it’s worth giving the subject some thought and having a conversation about it.

Industry 4.0 versus Manufacturing Improvement (Part 1)
There is a lesson that manufacturing leaders seem determined to learn the hard way: flooding factories with new technology does not improve their performance.
Roger Smith learned it at GM in the 1980s. Elon Musk, for all his other achievements, admitted by tweet to making the same mistake at Tesla last year.
To really improve manufacturing performance, you start with, as Crispin Vincenti-Brown put it, with “what happens when the guy picks up the wrench.” You work with that person to make the work easier, faster, safer, and less prone to deviations and errors. In doing this, you apply, as needed, technology you can afford that operators can work with.
This is hard work but it pays off. It is a key lesson learned from Toyota, TPS, and many companies that implemented it under the “Lean” label. But it’s an eat-your-vegetables message. The lure of a technological shortcut is irresistible.
