The other thing to keep in mind is that a lot of projects you may find yourself on you may run into issues of a project manager who views a project as their "baby" and becomes the chief impediment to fixing problems because they designed/coded it originally and they know what their product should be (in cases like that, if you can move to a different team, I recommend it--let the manager kill their own product). The other thing you will probably run into a decent amount is where everybody on a team uses the product and considers themselves a "user" and argue that they know what's best in terms of usability--that's where video clips of users flailing around the product are particularly helpful in convincing team members that a problem exists.
