There is a different point of view in performing function analysis depending upon who you are. Are you a designer or manufacturer of a product or are you a user of a product ? What could be basic function to one person might not be basic function to another.
Function analysis a system to show exactly what one gets for his money and, as such, records directly to the needs of the owner. It can show, that a good design can, at times, be stronger, more attractive, and less costly.
Most value analysis discuss and define three aspects of economic value:
aspects of value relates to
exchange value - worth
esteem value - want
use value - need
VE methodology concentrates on the use value of the "worth" or "sell" functions. Aesthetics normally is a subjective decision and, very often, an individualistic one. VE is a tool to bring more objectivity to the decisions on aesthetics, usually to gain group acceptance.
Esteem value is no more that] the desire of the owner to own it. Sometimes, an owner doesn't want it because it doesn't satisfy his desire - it doesn't please him aesthetically -he can't live with it, aesthetic functions become basic when desire becomes as strong as need.
