Applying Cognitive Psychology to System Development
Product designers need to wear many hats during the development process. These different perspectives
range from that of the product designer who is trying to invent and integrate new concepts within a
product, to the hardware/software engineer who is trying to create the physical realization of these
design concepts, to the manufacturing engineer who is trying to manufacture the product, to the market-
ing specialist who is trying to sell the product (Bralla, 1998).
