The double diamond diagram was developed through in-house research at the Design Council in 2005 as a simple graphical way of describing the design process
Divided into four distinct phases, Discover, Define, Develop and Deliver, it maps the divergent and convergent stages of the design process, showing the different modes of thinking that designers use.
Discover
The first quarter of the double diamond model marks the start of the project. This begins with an initial idea or inspiration, often sourced from a discovery phase in which user needs are identified. These include:
Define
The second quarter of the double diamond model represents the definition stage, in which interpretation and alignment of these needs to business objectives is achieved. Key activities during the Define stage are:
Develop
The third quarter marks a period of development where design-led solutions are developed, iterated and tested within the company. Key activities and objectives during the Develop stage are:
Deliver
The final quarter of the double diamond model represents the delivery stage, where the resulting product or service is finalised and launched in the relevant market. The key activities and objectives during this stage are:
Discover
The start of a project is marked by an initial idea or inspiration, often sourced from the Discover phase.
Define
The start of a project is marked by an initial idea or inspiration, often sourced from the Discover phase.
Develop
At the Develop stage the project has been taken through a formal sign-off, which has given the corporate and financial backing to the development of one or more concepts that have addressed the initial problem.
Deliver
The Deliver stage of the double diamond design process is where the final concept is taken through final testing, signed-off, produced and launched.
