Institutional inertia
This happens a lot. I was once a 'victim'. On a contract I was given a SparcStation that used to slow down a lot. It turned out it was being used to run distributed builds. The script compiled a list of units with spare capacity and then used them to do the build. Problem was, the list was only compiled once, and if you were unlucky you got piled on for a long time. There were better SparcStations around but they didn't always get used by the build.
Nobody really seemed to care about this. Except me.
So I rewrote the build script to keep up to date info on units with spare CPU and take account of the type. Life got a lot better after that. Most of the engineers were just following process and not caring much, especially if they had better equipment, unlike us contractors who got the leftovers. It also helped that they didn't lock down the script, of course.
