Software is often defined by what makes it different, but in many cases, the same UX and design problems appear over and over again; a pattern, across many applications. Rather than come up with a brand new solution for every problem - a solution that could require a tutorial to educate users - it's often best to turn to familiar solutions that a user will immediately recognize. These solutions are called design patterns, and when it comes to UX, these patterns can solve problems in the user interface and they can also help influence the behavior of users.
