Double diamond design process
Double Diamond is a design process model developed in 2005 by the British Design Council. Using a double diamond diagram, the method breaks down the general design process into four specific phases - discover, define, develop and deliver.
It is a method for using design process visualisation in a graphical way. It was adapted from a model proposed in 1996 by the linguist Béla H Bánáthy. Bánáthy created an earlier version of the model (based on the same four phases) as a method for examining social systems design theory. His study, 'Designing Social Systems in a Changing World', introduced a diagram for a divergence-convergence model which would form the basis of the double diamond design process.
 Product and service development tool
As a design process, double diamond emphasises problem analysis as the basis for creating a solution for the client. Its development was based on case studies gathered from the design departments at 11 global firms:
- Virgin Atlantic Airways
- Whirlpool Corporation
 Examining the phases
The discovery phase is based on an idea that arises and is then explored through methods:
