Product Redesign Using Value-Oriented Life Cycle Costing

A new redesign approach has been developed considering the perspective of a designer who wants to improve product performance over the whole life-cycle while simultaneously optimising costs. Product components can be identified which incur high costs compared to their functional value. In order to identify the optimisation potential, the methods of Value Analysis, Quality Function Deployment and Life Cycle Costing have been matched to each other and integrated into a comprehensive concept. Based on a case study of vehicles, this paper explains the theoretical approach and analyses for designers to optimise costs and conduct product redesign by using Value-Oriented Life Cycle Costing.
