No matter how usable an interface design is,, if the design is not well communicated to the developer the result may be unusable. A well specified user interfaces can also help designers to discover inconsistencies and usability problems before the interface is developed saving time and money. This is why specifying user interfaces using a formal technique is important. There are also many formal techniques available for specifying the look and functionality of graphical user interfaces, though in practice these specification techniques are rarely used. The result is development of user interfaces that are different than what was intended by the designer or envisioned by the customer and higher costs for detection and correction of usability problems.
