Yes, I too have seen the phenomenon of having too many people demanding features where the result turns out to be an incoherent mess. But I also know that if the massive amount of time and money that had been spent purchasing a box-ticking Enterprise Software Solution and subsequently hammering the awkward, unwieldy platform into some semblance of working order had been spent instead on direct improvements to the existing workflow software, then everyone would have been much more satisfied. And yeah I know I shouldn't speak hypothetically but you'll just have to decide to trust me on this or not.
Sometimes (I have no global numbers to even guess at how often), they end up discovering that the COTS product requires expert-level configuration and administration anyway and now they're footing the bill for someone else's licensed solution and a staffer to understand it and make it work.
... which adds features to the product as a whole, which other customers will need to be aware of and might take advantage of.
