Double Diamond: Tool for Design

Two diamonds sit side by side joined by one corner. The left hand one has discover and design, the right hand one has develop and deliver.Design isn’t just about tangible objects, it’s also about services and processes. This is where the Double Diamond of Design comes to the fore. The Design Council devised the Double Diamond as a way of graphically explaining the design process. The two diamonds represent a process of exploring an issue and then taking focused action. The key elements of this model are:

Discover. The first diamond helps people understand, rather than simply assume, what the problem is. It involves speaking to and spending time with people who are affected by the issues.
Define. The insight gathered from the discovery phase can help you to define the challenge in a different way.
Develop. The second diamond encourages people to give different answers to the clearly defined problem, seeking inspiration from elsewhere and co-designing with a range of different people.
Deliver. Delivery involves testing out different solutions at small-scale, rejecting those that will not work and improving the ones that will.

The latest iteration of the Double Diamond is available in a PDF document. This model now has a fifteen year history. The Design Council has much more on their website about their Double Diamond and how to use it.
