USER INTERFACE SPECIFICATIONS

A user interface specification describes every aspect of a design that the user experiences, including screen layout, software and hardware behaviors, state changes, error messages and dependencies. A specification:

Provides specifics so engineering doesn't have to waste time working out the UI details (which usually aren't describe in functional specs).
Is detailed enough that QA can test the actual product against it.
Tracks open issues and serves as a repository for design decisions.
Preserves ideas for future enhancements.
