Co-Design is therefore erasing the line between the designers and the users, and increasing the idea that the solutions are developed for ourselves.
The co-Design is based on three different and precise concepts :
Therefore co-design is based on time saving and optimization of the conception phases. Co-design reduces the unforeseeable aspects of a technical object’s development.
Time after time, co-design lead to human centered design, which is a philosophy and a conception approach in every domain where the expectations and characteristics of the end users are taken into account at every stage of the development process of the product.
The conception approach is based on the final consumer himself, as the idea here is that they are best to evaluate and use the product. Therefore the development of a product is guided by needs and requirements of the final users instead of the technical possibilities or technologies.
In order to follow each step of the conception, there are three stages
