A model-based risk management approach - marketing vs safety case study

Abstract

There may be many points of view that need to be considered when identifying, defining and assessing risks. A contextbased approach supports the identification and understanding of risks as well as providing a focus for risk assessments through the application of different viewpoints. This paper uses the ability to focus on viewpoint to provide the identification of concerns and risks. It discusses ways to identify system views from which concerns can be elicited and proposes the views needed to present cause and effect analysis. Finally, mitigation views will be discussed which are used to present possible system changes based on the results of analysis. A safety critical situation directly related to marketing and business needs will be discussed. This case study will show how the views can be used and how they integrate with existing Model-Based Systems Engineering (MBSE) approaches.
