In this publication a new enhanced V-Model for interdisciplinary product engineering is presented. The new approach comprises continuous requirements elicitation and management, comprehensive modeling and analysis and emphasis on the entire product life cycle. The proposed V-Model unites the models of different development methodologies, e.g. VDI 2221 [3], Systems Engineering [4] and elements of the contemporary VDI 2206 [2]. This new approach is inspired by discussions led within the Technical Committee VDI GMA 4.10 "Interdisciplinary Product Creation" of the Association of German Engineers (VDI).
