Participatory Design
Participatory Design is a design exercise that invites the intended users of the system to roughly draw out how they would like the system to work.
The exercise typically encourages small groups to work together to map out a critical user journey within the system. During the exercise, groups are asked to explain why they have included the elements they have and to talk through how these different elements work. With larger participatory sessions, different groups tackle the same journey, which can generate discussions around different design ideas and approaches.
