Patterns
I am a big fan of patterns and prints, especially with lots of color. But just doing whatever you like everywhere is not always the right way to go. Design patterns, component libraries or even style guides have become the norm for organizations large and small. It gives designers familiarity and efficiency. This in turn frees up designers' time to focus on bigger problems. Like solving the needs of their users. In theory anyway.
The use of design patterns, no matter how complex it may be, should never stifle creativity or slow down design progress. To achieve what they promise, they must be adaptable, flexible and scalable. A good design pattern is not dependent on context and is unobtrusive.
