Double Diamond
The Double Diamond is a Design Council model that represents the exploration and narrowing down of a problem and its possible solutions
What it means, how it is used and where it comes up, with its related concepts.
What it is and how it works
It organises the work into discover, define, develop and deliver. The diamonds alternate divergent and convergent thinking. They do not describe a rigid sequence: teams can go back to research or redefine the challenge as they test their ideas.
