Today's products and systems in the Aerospace and Defense industry are becoming more complex with new technologies rapidly disrupting the traditional norms such as autonomous functions and electrification. Disruptive innovations are creating an environment of "art of the possible", which unfortunately also creates new threats to maintain compliant and safe systems. On this front of A&D there is a call for "digital engineering initiative", looking at these suppliers to adopt digital techniques that enable a leap in speed and efficiency of bringing new systems from concept to operational state. The IBM engineering lifecycle platform (ELM) offers a set of capabilities that enable such a transformation of the engineering process along the line of the digital engineering initiative. In this talk we will present the core capabilities of the ELM platform supports digital engineering principles and more specifically A&D industry practices such as ISO 15288, INCOSE SE Handbook, and safety means of compliance such as ARP 4754 and DO-178C. We will look at an "end to end" practice from early stakeholder needs to verification and validation, involving advanced approaches such as model based engineering, agile systems engineering and AI to realize the digital engineering vision.
