I can tell Dilbert is not a manager. If he was a manager, he would have demanded those changes be done by END OF DAY.
This sounds like most IT Projects I worked on at IBM. For one of our clients we have a brand new server cluster gathering dust while we wasted the last 2 years "stabilizing" the very old one we it was supposed to replace. Countless months working P1 calls and teams pushing back on getting this completed.
