TECHNICAL SESSION As systems grow more complex, development programs grow larger and more difficult to execute successfully. Challenges in meeting cost and schedule targets show up across all industries in complex systems development. Recent research shows that correctly applied systems engineering approaches can make a significant impact on cost and schedule risk. This led to the Advanced Systems Engineering initiative, a set of concepts and directions aiming at improving program execution.
Though many buy into the mantra, “models are the answer” in systems engineering, we must distinguish what makes a model, a model. Beyond particular modeling languages and diagram types, models exist for various purposes, and can have relationships with each other, forming a kind of “model of models.” In Advanced Systems Engineering, the relationship between models and requirements is also changing and evolving to include both model-driven requirements and requirements-driven models.
