At my current job we were supposed to have switched to Rally. However, the PMs prefer Excel. The result is that a spreadsheet on the PM's computer is the real system of record and sometimes things make it into Rally. This is a terrible experience. I've abandoned both systems and just work on whatever I feel like. Luckily I have enough clout and a slightly unique role that I can get away with doing this. I feel awful for the devs who are supposed to be working on the normal dev tasks.
