A great example of this is tax departments at large companies that look for tax avoidance strategies. On one hand, these strategies can save companies many millions of dollars, but on the other, they really produce nothing of value and are just a product of the complexities of a (human designed) tax system. Lots of regulatory compliance work also goes into this bucket. I wouldn't say all of it, because there are definitely regulations that do actually make companies safer/more transparent/etc., but anyone who has had to fill out a page after page after page "security questionnaire" knows at least half of it is bullshit that nobody is going to read in the first place. Sometimes I've been tempted to just add "Mickey Mouse" answers just to check if anyone sees it. Writing something that nobody ever reads seems like it's hard to believe that's anything else except bullshit.
