Extended VPD benefits
The prototype’s realistic-looking functionality
enhances understanding of a product concept, its possibilities, and its
limitations. Nokia first used the prototype
to support the decision-making
process and to sell the product concept
within the organization. When Nokia
decided to go ahead with the concept and
build a hardware prototype, the company
gave the job a subcontractor and
used the RFID RWS prototype for communicating
the product concept. The
simulation served as the specification; no
formal descriptions were required. The
targeted hardware prototype design differed
somewhat from the design depicted
in Figure 3, but it was also a key chain
and its functionality was the same.
