We know a thousand ways not to build a light bulb. Thomas Edison
The larger the pool of solutions, the greater the chances of finding the best. Workshops encourage idea generation and problem solving bringing together the team members and the client: brainstorming, six-to-one, role playing, and other design games. Then, we evaluate the imagined solutions to select the best candidates.
Prototyping is the best way to assess the adequacy of a solution and improve its functioning continuously.
Prototypes start as simple sketches and are refined with the time, going from paper prototypes to wireframes to interactive graphical models. Every prototype can provide the basis for a series of tests.
