Co-design consists in taking the user into account throughout the process so that he can understand the issues and objectives while being an actor in the project, so that the designer makes sure to respond correctly to his needs.
The use of co-design constitutes major challenges for designers and users such as:
Co-design must follow a well-defined approach to be properly implemented:
Based on the previous phases, designers and developers will materialize solutions. These can take different forms, from the sketch to the mock-up until the final product, including intermediate stages such as dynamic mock-up and prototypes. It is a question of proposing solutions in various forms allowing rapid changes which will make it possible to validate the design choices. These steps make it possible to easily explore design alternatives and validate them with users, through tests and trials, and finally to improve the quality of functional specificities.
After the design phase, the product is finalized and implemented in the work activity. The research work carried out upstream is done so that the final product meets expectations and can meet the needs of what it was designed. However, there are many issues that can arise after installation. This is the reason why a follow-up is ensured to improve the product and the avenues for reflection.
