Double diamond

Meaning in UX/UI design, with examples

nounAdvanced term

In UX/UI design, double diamond means: A design process model with four phases, discover, define, develop and deliver, drawn as two diamonds to show thinking that first opens up and then narrows down.

In Turkish: çift elmas modeli, double diamond

How it is used

Introduced by the UK Design Council in the mid-2000s. The first diamond is about finding the right problem, the second about finding the right solution. Designers use it to explain where a project is: 'we're still in the first diamond'.

Example sentences

  1. We're in the define phase of the double diamond, so it's too early to talk about screens.

  2. The double diamond reminds us to explore the problem before jumping to solutions.
