Big companies can end up driven by incentives that are at best orthagonal to basic economics which means you often can't convince people to do things that make sense because they make sense.
If individuals are judged based on results against goals declared at the start of the period, they will tend not to do anything other than that. You can't say "the users want this", or "this will save $5 trillion dollars", or "we can't do our job without this" because those things don't matter to individuals. Instead, you have to argue for it to be put on a roadmap, or convince your management to convince their management to push them to do it sooner than 18 months from now. And you have to do it with a light touch, or there will be resentment.
