Bridging the Gap Between Requirements, Architecture and Implementation

How can we perform systems engineering tasks associated with standards like ARP 4754 & ISO 26262 part 4, while ensuring the key derived requirements filter down to the implementation? Performing large scale system design and upgrades is a task of ever-increasing complexity. Traceability and synchronization across all design levels is key to streamlining large scale development programs. However, there is often a missing link between systems engineering and design implementation in top-down design process. In this presentation it will be demonstrated how to bridge the gap between systems engineering and implementation in a top down legacy systems upgrade project. The example case study shall follow the update of key system level requirements & architectural modifications down to identification of the required design implementation. Finally, a system level trade-off analysis shall be performed to assess the high-level impact of the upgrade on the complete system.
