How can the "double diamond" model help in the design process?

The "double diamond" design model breaks down the design process into four phases: discover, define, develop, and deliver. The first two phases, discover and define, emphasize understanding the problem and its context, involving research and user analysis to generate a clear understanding of the problem. The second two phases, develop and deliver, emphasize generating ideas and then creating the actual product. This model encourages designers to explore multiple possibilities at each step before converging on the best solution.
