Double diamond design process



[edit] Introduction

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.

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:

  1. Alessi
  2. BSkyB
  3. BT
  4. LEGO
  5. Microsoft
  6. Sony
  7. Starbucks
  8. Virgin Atlantic Airways
  9. Whirlpool Corporation
  10. Xerox
  11. Yahoo!

[edit] Discover

The discovery phase is based on an idea that arises and is then explored through methods:

[edit] Define

The definition phase ties the findings of the discovery phase to business goals. The activities of this phase include:

[edit] Develop

The development phase develops and tests solutions that are design based to see how they will actually suit the business goals. These activities include:

[edit] Deliver

The delivery stage is marked by the introduction of the product or service that has been proposed. Activities during this stage include:
