The technological progress is highly responsible for how people live their everyday life. Technical innovations provide new opportunities to re-design all areas of life and because of that the society has to adjust to these changes permanently. These days, due to the fact that there is a changeover from analog into digital processes, this circumstance is highly relevant. However, it is not always clear whether a technological innovation just entails chances or involves risks, too. The research field of technology assessment pursues the goal to examine the influence of technological innovations on the society. For this purpose, unpredictable consequences of a technology need to be anticipated in advance to provide the opportunity of earlier reactions. The core of this thesis a discussion about a project based approach of technology assessment. Additionally, it is being investigated whether and how systems theory approaches can be used to improve predictions in the research area of technology assessment. Therefore, the question of how reliable forecasts are in this kind of context will be answered. Moreover, there is an investigation if an added-value can be created through performing system thinking. As a methodical approach a literature review has been performed. Furthermore, experts were questioned in an interview and by e-mail to gain an insight in the practical work of technology assessment. Based on the elaborated project structure, for each part of the project was examined if significant results can be maintained through the sophisticated use of principles of the systems theory. The analysis of this paper has shown that the results of a technology assessment may have more reliable forecast value in comparison to an investigation without proper consideration of system thinking. Especially, the understanding of a system during the phase of conception of a project can be crucial for the positive outcome for the results of technology assessment. This master thesis represents the theoretical point of view regarding topics technology assessment and systems theory. An application test for the validation of the results in the practical work of technology assessment is recommended.
