For many companies, especially from machinery and plant engineering, competitive edge more than ever stems from technological lead. The key to success though not necessarily lies in applying technologies in final products. Usually, in the context of a particular technology or technology-field a multifaceted value network emerges, which contains various options for positioning. For companies there is no methodological support yet on the way to tapping an advantageous position in a technology-induced value network. Goal of this thesis is a method for positioning in technology-induced value networks in the context of strategic product planning. Therefore, todays roles in a value network are worked out inductively. In the following, foresight of future developments and possible future roles is conducted. On the basis of these results, attractive target-roles for future positioning are determined. For those, entry barriers and information of access, like typical partnerships, are worked out, which are subsequently used in order to shape the own role. The ideas generated in doing so are rated and arranged chronologically. For ideas with a high degree of uncertainty an evaluation support using Monte-Carlo-Simulation is provided. Finally, future cooperations are planned. The result of the method is an access roadmap, which specifies which actions are conducted with which cooperation partner.
