This presentation explores how we have started to transition to using MBSE for Insulin Pump development. Despite MBSE being heavily prevalent in DOD and aerospace for years, there has been minimal documentation of its use in the medical device field. This presentation will look at our approach to onboarding a team of system engineers with little to no experience in Catia Magic. This presentation will examine how we are creating ecosystem level views to help identify high level impact due to changes across different domains. We will explain our content prioritization strategy for achieving integration and SysML compliance. This presentation will show our approach to using both the logical and physical domain as well as how we are handling variants in both structural and behavioral diagrams.
