Sounds like a lack of repeatability to me: complex tools, combined with lack of documentation, makes for a fairly unstable work environment.
It's for similar reason that I like to keep unreliable dependencies to a very strict minimum. I can rely on my compiler, my editor, my OS, and to a lesser extent a bunch of extremely popular libraries. But as soon as we get to internal tools & processes or obscure third party libraries, certainty goes downhill very quickly.
