Axiomatic design method starts with customer needs and expectations that translated to top level functional requirements then to top level design parameters and also top
level process variables. Each of these four characteristics forms a domain. These domains are so called Customer, Functional, Physical and Process domains. The domains are decomposed from highest level of conceptual design to detailed design, hierarchically. After assigning the top level requirement(s) to design parameters at the same level, functional requirements will be decomposed and mapped back to their design parameters but at a lower level. This zigzag process continues between domains until design is completely decomposed [7] and design matrix is extracted. This process
has been done here for Bonded Repair Design Technology.
