Once we defined a correct framework, is the time to ideate and develop solutions. There are several models to generate ideas: from the reassessment of the hypothesis found (what if) to the generation of forced connections (hybridization).
An idea without execution is worth nothing. Prototyping is the part of the design process that consists of materializing the ideas. It is the way to define and communicate an idea rapidly. That's how we prompt new questions and reveal the latent needs of ideas development and execution, and new information seeking.
