In this first webinar in the series, we introduce Model-Based Design and discuss why it can provide value over traditional software development processes in certification workflows. We then introduce an example Model-based Design software development workflow, including a high-level discussion of each step in the process and the corresponding tools involved. The goal of this introductory webinar is to provide sufficient background of the overall process to provide the appropriate context for viewing of each of the other parts of this webinar series.
