Silence like a cancer grows “Fools,” said I, “You do not know Silence like a cancer grows Hear my words that I might teach you Take my arms that I might reach you” But my words like silent raindrops fell And echoed in the wells of silence Paul Simon & Art Garfunkel, The Sound Of Silence silencediseaserain
Deciding what to design We Don’t Really Know the Goal When We Start The most serious model shortcoming is that the designer often has a vague, incompletely specified goal, or primary objective. In such cases, the hardest part of design is deciding what to design. I came to realize that the most useful service I was performing for my client was helping him decide what he really wanted. Today, we recognize that rapid prototyping is an essential tool for formulating precise requirements. Not only is the design process iterative; the design-goal-setting process is itself iterative. Knowing complete product requirements up front is a quite rare exception, not the norm. Therefore, goal iteration must be considered an inherent part of the design process. Frederick P.
