As the desires of market get various, so its demand fluctuates frequently. The only companies that flexibly meets fluctuating demands can survive in the fierce market competition. In this study, we deal with the development of jig system for manual welding processes that can cause flexible actions and uniform quality in the manufacturing shock absorber base assembly of automobile. For this we review the processes of design and development through analysis of the technology and the customer that are patents analysis, customer desires analysis, functional analysis and so on. Moreover, we review the relevant indicators for improvement of productivity that are production capacity, cycle time and error rates etc. as the technology is developed.
