The present dissertation deals with the adjustment of test scenarios of technical prototypes. The overall objective of this research work is the development of a concept for the detection of differences between defect and non-defect products concerning the redesign of test procedures and application of the obtained knowledge during the test phase of the next generation products. An essential part of the presented concept is the application of various machine learning algorithms as well as goal-oriented interpretation of the results and deduction of corresponding conclusions. The proposed concept has a generic character and is suitable for all products in the consumer and investment goods sector, in which the possibility of the field data gathering is given. The application of the concept is performed based on various examples from the automotive industry.
