Usable, Useful, Desirable

On noise between stations, Victor ponders Liz Sanders' phrase Usable, Useful, Desirable and the different ratios of usability, usefulness, and desirability that might apply to different project artifacts, depending on project team expectations. It's an interesting idea, because measurement of these qualities depends largely on the purpose and utility of the artifact. His coffee maker analogy is precious. Illustrates that measurement/assessment of qualities of the object is tied to the user and their intentions/desires.
