Creating new products can be a hard bargaining and a question of colliding interests. Because economists and technicians easily prove their points with statistics, charts and measurements, designers need methods to validate their soft values. Saying “this could be a good idea” just isn´t enough.

One of the user driven methods explored in female interaction is the value proposition method. A value proposition unfolds the value of a product to the users in abstract terms.
E.g. the value proposition of a wrist watch is "a personal portable time measurement and indicator". This more abstract definition tears apart the predefined "picture" of a wrist watch and opens up for new innovative views on time measuring devices.
