User Centred Design

We are using User Centred Design or UCD to design this vehicle.

"There is an international standard that is the basis for many UCD methodologies. This standard (ISO 13407: Human-centred design process) defines a general process for including human-centered activities throughout a development life-cycle, but does not specify exact methods."
