Is it necessarily true that a bullshit job has to server no purpose? I think a doorman is like the safety video. It makes the product feel more expensive. I agree it's a bullshit job, but it contributes to the impression your company is making. Maybe a well produced Analytics Report makes a sort of impression like this too. At a glance you can prove you are a high end company that has everything together, and produces sophisticated reports as evidence. Even if it's a bullshit report, spending 5 figures to make the report is worth it, if it secures a bunch of 6 figure customers.
I'm not saying we should secure bullshit jobs, I'm just trying to voice some more perspective.
