Double Diamond is a design process model popularized by the British Design Council in 2005. The process was adapted from the divergence-convergence model proposed in 1996 by Hungarian-American linguist Béla H. Bánáthy. The two diamonds represent a process of exploring an issue more widely or deeply and then taking focused action . It suggests that, as a design method, the design process should have four phases:Discover: Understand the issue rather than merely assuming what it is. This phase involves speaking to and spending time with people who are affected by the issues. To find out the same problems faced by users. Define: With insight gathered from the discovery phase, define the challenge in a different way. Develop: Give different answers to the clearly defined problem, seeking inspiration from elsewhere and co-designing with a range of different people Deliver: Test different solutions at a small scale, and improve the solutions that are satisfactory to the users. Reject those that will not work.
