Double Diamond is a design process established by The British Design Council (2019). This is a great design process overview which could apply on the most of this project. This report is using Double Diamond and suggests to use it in the future design process. There are four steps in this process and those four steps can be divided into two sections. The first part is about research, the design manager identified the problems as much as possible by using divergent thinking. In accordance with the problems, the design manager decided which can be solved to create a design brief. The second section is the actual design stage, designers should consider the solutions based on the design brief. The deliver stage is to choose the possible solutions from the development stage and get a final design concept and outcome. If necessary, this process can start over again (Hartog 2016).
