Co-design

Co-design is the process where the designer encourage and guide users to develop solutions for themselves.
Is a term, short for collaborative design, that means a community centred methodology that designers use to develop a partnership with a product or service’s end users, in order to make their solution more effective. ( From the Design Council, Design Glossary)
The co-design has its roots in the Kant's book Critique of Pure Reason, that says "to ask a question, you need to have some information or knowledge."

According PM Davies, co-design is the process of involving people in the design process with the aim of creating a better product or solution.
