Abstract:

As a rule of thumb, the earlier in the development process reuse can occur, the more efficient reuse becomes. Like software component reuse, the reuse of UX design elements can be a very efficient form of reuse—particularly because this form of reuse occurs very early in the product development cycle. The ability to reuse prior work effectively is one characteristic of a mature discipline.
