Automated driving is the most disruptive innovation for future mobility. To bring automated driving functions towards market maturity, huge challenges in development, Validation and release process need to be overcome. Additionally, the organization of work must be adapted due to growing complexity of such systems. Recent research suggests scenario-based methods, usually for testing, since established methods such as statistical testing are not adequate for Validation and Verification of future driving functions. To cope with the competition in developing and testing automated driving functions, we propose a method for continuous usage of scenarios in the systems engineering process. This presents the advantage of dividing complex and intangible development goals in smaller manageable tasks. Moreover, we show how scenarios, following the OpenDRIVE and OpenSCENARIO Specification, are used for target-oriented Validation and Verification. While applying the scenario-based systems engineering (SBSE) approach, various artifacts, e.g., textual and formal scenario descriptions, customer and system oriented use cases as well as state, flow and activity diagrams are generated. This supports in planning, organizing and tracing the development and Validation process. Hence, the technical progress of the target system becomes apparent at an earlier point of time and the development effort and costs get estimable.
